Professional Support, Feasibility Studies and Planning Appeals

Many users searching for obtaining planning permission in Cornwall are looking for professional services that can support them through the process. Experienced Cornwall Architects and planning consultants can assist with early feasibility studies to test whether a proposal is likely to be acceptable in planning terms before significant costs are incurred.

Professional support can also be critical when dealing with planning refusals. Planning appeals require a clear understanding of policy, evidence, and decision-making rationale. Working with experienced professionals can help applicants respond effectively to refusal reasons and present a stronger case at appeal stage.

For projects requiring careful navigation of local rules, heritage considerations, or complex sites, our team at Lilly Lewarne Architects offers comprehensive support from early feasibility studies through to planning submissions and, where necessary, planning appeals. We work closely with clients to develop well-prepared proposals that align with Cornwall Council’s requirements and local policies, helping to increase the likelihood of timely approval and successful project delivery. Contact us to discuss your project.

Public Consultation and Interested Parties

Once validated, planning applications enter a consultation period. This allows interested parties and stakeholders to review proposals and provide feedback. Consultation typically includes neighbours, nearby businesses, parish or town councils, and statutory consultee’s such as highways or environmental bodies.

All feedback received during consultations is reviewed by the assigned planning officer and forms part of the decision-making process.

Planning Permission, Building Regulations and Building Control

Planning permission and building control are separate processes and serve different purposes. Planning considers whether development is acceptable in principle and in its local context. Building control makes sure the project is built properly, it focuses on compliance with building regulations, including safety, structure, and energy performance.

Knowing the difference between planning permission and building regulations is important. Failing to obtain the correct permissions can result in enforcement action, delays, or costly remedial works. Approval from one process does not automatically mean approval from the other, and most projects require consent from both before construction work can begin.

Land costs, plot cost, and site realities

Land is one of the biggest variables in a self build project. Across much of the UK, plot cost typically ranges from £150,000 to £300,000+, though this varies widely by location.

Plot costs are influenced by:

• Planning status
• Proximity to services
• Access and visibility
• Ground conditions

A cheaper plot can require more budget later if it needs extensive groundworks, long service runs, or mitigation such as replacing protected trees. These factors are often underestimated and can increase the project cost significantly.

Sites with existing structures can sometimes reduce costs, but they can also introduce risk. Structural unknowns, demolition requirements, or restrictions imposed by local authorities can all affect the build budget.

Planning permission, building regulations, and compliance

Planning permission is a critical milestone in any self build project. While the application fee itself is relatively modest, planning conditions can significantly affect house building costs. Requirements for specific construction materials, drainage plans, or ecological mitigation can add substantial cost.

Building regulations also influence build costs. Modern standards require improved insulation, airtightness, ventilation, and tighter fire safety measures. These requirements are reinforced by the Building Safety Act and the wider focus on building safety across the construction industry.

Energy performance requirements are closely linked to the UK’s carbon reduction commitment. While these standards increase upfront costs, they also improve comfort, durability, and long-term house value.

Construction systems and build methods

The construction system you choose has a major impact on build costs, programme length, and performance.

Timber frame construction is popular with many self builders. A timber frame structure can be erected quickly, reducing time on site and helping to manage lending costs, particularly when using a self build mortgage. Timber frame can also support energy efficiency and maximise usable floor space.

Traditional masonry construction remains common, especially where local builders are familiar with brick and block methods. However, longer build times can increase labour costs and lending costs.

Oak frame construction sits at the more premium end of the market. Oak frame homes offer character and longevity but usually come with higher build costs and require careful cost control elsewhere in the project.

Project management, Professional fees and technical input

Project management choices have one of the biggest influences on self build costs. Using a main contractor simplifies coordination and reduces risk, but the builder’s profit margin is built into the price. This typically increases build costs by around 15–20%.

Some self builders choose to project manage their build project themselves to save money. This can reduce costs, but only if there is strong organisation and exercising close cost control. Appointing a project manager can balance professional oversight with cost efficiency. A good project manager helps manage trades, sequencing, and quality, reducing the risk of delays and rework.

Professional costs typically account for 7–15% of the total project cost.

These cover design, planning submissions, compliance with building regulations, and coordination during construction. Clear drawings and detailed professional plans help contractors price accurately and reduce disputes. Poor documentation often leads to variations that increase the overall cost.

VAT reclaims and reducing the total cost

Typical VAT reclaims range from £7500 to £25,000.

Most self build properties used as a main residence are eligible for VAT reclaims on all the normal materials used in construction.

To reclaim VAT, you will need planning approval, invoices, and a project completion certificate. Good record-keeping from the start simplifies this process.

Final thoughts – Is self build good value compared to buying?

Compared to buying an existing property or a typical developer house, self build often delivers better quality and performance for the same or lower total cost. Many self builders also find that the completed home has a higher house value than the project cost. For most self builders, the goal is not just financial return but creating an own home that works better for daily life.

Self build costs in 2026 are substantial, but they are manageable with good planning. By understanding average cost figures, setting a realistic build budget, allowing for a contingency fund, and maintaining close budget control, self builders can deliver a successful project.

A well-managed self build is not about spending the least possible. It’s about investing wisely, meeting regulations, and creating a high-quality home that performs well for decades to come. Visit our blog home for more architecture and design articles.

Conservation Area Considerations

If your property lies within a conservation area or other designated land, stricter rules apply. Permitted development rights are often limited or removed entirely, meaning most extensions or new walls will require planning permission.

A local planning authority may also restrict your use of materials, finishes, and height to preserve the area’s character. If you plan to build near a shared boundary in a conservation area, you’ll almost certainly need to serve a party wall notice and agree terms with adjoining owners.

A party wall surveyor familiar with conservation work can help ensure compliance and maintain good relations between neighbouring properties. They can also advise on fence positions, garden walls, or adjacent excavation if your foundations are within 3 metres of a neighbour’s land.

Additional Resources and Further Reading

Understanding your development rights, boundary lines, and planning requirements is key to a successful project.

Helpful resources include:

• The UK Government Planning Portal – for guidance on permitted development and planning permission
• The Party Wall Act 1996 – for official rules and templates for party wall notices
• Your local council’s planning department – (Cornwall council in our case) for advice on local planning authority procedures and conservation rules

If you’re planning an extension or new construction work near your neighbour’s boundary, our team at Lilly Lewarne Architects can assist with site analysis and boundary confirmation, preparing and submitting planning applications, liaising with party wall surveyors, and designing context-sensitive solutions tailored for Cornish homes and heritage buildings.

Stage 3: Spatial Coordination

Stage 3, known as spatial coordination, develops the design in detail and ensures all elements work together. Structural engineers and building services consultants collaborate closely so that all systems integrate within the architectural design.

Detailed drawings and design reviews refine the developed design to meet the client’s requirements and statutory standards. Planning applications are prepared and submitted, supported by Design and Access Statements that explain the proposal to the local planning authority.

During this phase, construction professionals refine specifications, assess project risks, and prepare for the tender process. The result is a coordinated design that balances creativity, compliance, and practicality.

Stage 4: Technical Design

The technical design stage provides complete information for construction. This includes detailed architectural drawings, specifications, and key performance data for every part of the building.

The design team then finalises building systems, materials, and details while ensuring full building regulations compliance. Applications for approval are submitted to building control with structural calculations and any necessary fire safety details.

Tender documentation is prepared so contractors can price the construction stage accurately. The cost plan is reviewed again and value engineering applied where possible. Coordination between the architect and consultants ensures a seamless transition from design to build.

Stage 5: Manufacturing and Construction

Stage 5 marks the beginning of construction work. The main contractor manages site logistics, health and safety, and the construction programme. The architect monitors progress with site visits and inspections to ensure quality and adherence to the approved design.

Throughout this construction stage, any questions or clarifications are handled quickly to prevent delays. Building control officers carry out inspections at key points, including foundation depths and final inspections, confirming that building regulation compliance is met.

At this point, the project team ensures the design intent is delivered accurately on site.

Stage 6: Handover

When construction work is finished, the project moves into handover. The architect and client inspect the completed building to confirm that it meets the project brief and contractual standards.

The building contract concludes with final account settlement, while operation and maintenance manuals are issued to support long-term building performance. The defects liability period begins, usually lasting 12 months, giving contractors time to correct any issues found after completion.

Certificates from building control and planning authorities confirm compliance and allow occupation. At this point, the completed project becomes ready for use.

Stage 7: In Use

The final stage, called In Use, focuses on post occupancy evaluation and long-term building performance. Energy use, comfort levels, and user feedback are reviewed to assess how well the building meets the client’s initial requirements.

The design team may help with maintenance planning, lifecycle cost assessments, and potential future adaptations. Lessons learned are documented to improve future architectural projects and ensure ongoing project performance.

This stage reassures the client that the completed building continues to operate efficiently long after handover.

The Value of the RIBA Plan

The RIBA plan of work provides a clear structure for managing projects of all scales and locations including bespoke homes to larger developments across Cornwall and beyond. It allows a seamless transition between design stages and keeps quality control and cost management consistent throughout the construction project.

By following this framework, construction industry professionals and clients achieve reliable project outcomes, and ensure the completed project performs effectively for many years to come.

As leading architects in Cornwall, our design process is guided by the RIBA plan framework. We combine creative thinking with technical expertise, balancing sustainability, context, and precision to deliver buildings that meet both aesthetic and practical goals.

Final Thoughts

Understanding the RIBA work stages explained is essential for anyone starting a construction project in the UK. From stage 0 strategic definition through to in-use evaluation, the framework offers structure, accountability, and assurance that your project will be delivered to the highest standard.

At Lilly Lewarne Architects, we use the RIBA design stages as a clear and structured reference throughout every project, ensuring that each phase, from initial concept to completion, follows a consistent, transparent, and client-focused process

For clients, the RIBA plan of work provides a trusted path from concept design to completed construction, ensuring that every stage of the construction process is handled with clarity, care, and professional integrity. Head back to our blog for more architectural articles.

Local Council Variations

While national standards provide a baseline, local council regulations can vary significantly. Local councils may impose stricter minimum size requirements for double rooms, typically setting the floor area at around 11 square meters. Consulting local planning authorities for specific regulations related to layout and facilities when establishing a single bedroom is important.

Failure to comply with these regulations can lead to enforcement action from local councils. For precise regulations, individuals planning to build or convert a house should always consult their local council’s planning department regarding their project and the rule they must follow. This ensures compliance with the law and avoids potential legal requirements, making the process smoother and more efficient.

HMO Size Regulations

Houses in Multiple Occupation (HMOs) have specific bedroom size regulations to ensure adequate living conditions. The minimum room size requirement for HMO bedrooms in the UK is 4.64 square meters. Some local authorities also require a minimum ceiling height of 2.3 meters over at least 75% of the usable room area, ensuring that rooms are not only spacious but also comfortable.

Landlords must comply with these requirements to avoid overcrowding and provide a safe living environment. Rooms with a ceiling height below 1.5 meters do not count towards the overall size calculation, and local housing authorities recommend no more than two persons per one bedroom. It is important to consider how many people can safely occupy each room. This compliance ensures HMOs provide a quality living experience for tenants.

Building Control Considerations

Building control considerations play a crucial design role, ensuring safety and functionality. Building regulations mandate sufficient space for movement in bedrooms, especially to accommodate individuals with disabilities. Clear access routes must be maintained around furniture to ensure functionality and safety.

The minimum headroom for habitable rooms in residential buildings is typically set at 2.4 meters. The Housing Health and Safety Rating System (HHSRS) also assesses risks related to room sizes and living conditions. These considerations are crucial for creating safe and comfortable living spaces that meet regulatory standards.

Planning Tips for Small Bedrooms

Planning small spaces requires clever design and thoughtful furniture arrangement. Smart storage, multi-functional furniture, and design tricks can make a small bedroom functional and comfortable. A good plan maximises space while meeting minimum size requirements.

Smart Storage Solutions

Using vertical shelves and wall-mounted storage keeps floor space clear and makes the room feel more spacious. Under-bed storage drawers efficiently use wasted space and help keep things organised.

Multi-Functional Furniture

Furniture with built-in storage or dual purposes, like beds with drawers or desks that double as tables, improves flow and functionality. Inspired by space-saving designs from cultures like Japan, these ideas work well in UK homes.

Design Tricks to Enhance Space

Light colours, mirrors, and good lighting create an open feeling. Choosing furniture scaled to the room and avoiding clutter helps maintain a more comfortable bedroom.

Summary

Understanding minimum bedroom size regulations is crucial for ensuring comfort, compliance, and property value. Adhering to these standards can prevent legal issues and enhance the overall living experience for you, your guests of your tenants. By applying these design tips, homeowners and self builders can maximise the functionality and appeal of their bedrooms. Armed with this knowledge, you can make informed decisions that benefit both your lifestyle and property investment. View our other articles for design tips.

Cost Breakdown for Removing a Load Bearing Wall

The cost of removing a load-bearing wall can vary greatly. This variation is influenced by several factors. On average, homeowners can expect to spend between £2,000 to £4,750. These costs are influenced by labor, materials, and additional expenses, which will be detailed in the following subsections.

Labour Costs

Labour costs are a significant part of the overall expense. These costs typically include:

• Time spent on preparatory work, such as dust protection, structural bracing, and site clearance, adds to the total labour hours required
• Hiring a surveyor or architect to calculate the necessary support after the wall is removed, costing around £500 and to create architectural plans can be more costly.
• If a party wall agreement is needed, an additional £1,000 for assessing plans and writing a report.

It’s crucial to budget for these substantial labor costs and professional services to ensure the project is completed safely and efficiently. Proper planning and hiring the right contractors with experience can help mitigate unexpected expenses.

Material Costs

Material costs are another significant factor in the overall expense of removing a supporting wall. The cost of an RSJ beam for a large open-plan area of around 4 meters can range from £900 to £1,100. Additionally, the average cost for installing structural supports during wall removal is between £800 and £950.

The installation of these materials typically takes one to two days, depending on the size and complexity of the project, which can be time consuming. Accurate cost estimation requires consulting with suppliers, considering factors such as load requirements, span length, and the integration with the existing structure.

Additional Expenses

In addition to labor and material costs, there are other expenses to consider. Hiring a skip for waste removal can cost between £150 and £440, depending on the size. Floor levelling is another potential cost, ranging from £10 to £200 per square meter, depending on the materials used. Plus any making good of the wall scarring will add to labour and material costs. These additional expenses can add up quickly, so planning ahead for them into your budget is important. Proper planning and consultation with professionals involved can help you manage these costs effectively.

Choosing the Right Support Beam

Choosing the right support beam is crucial for maintaining the integrity of your home after removing a load-bearing wall. RSJ beams, commonly made of a steel beam, are known for their durability and load-bearing capacity. There are two primary types of RSJs. These are H-cross and I-beams.

An LVL (Glulam) beam is often preferred for its strength and ability to span greater distances without additional support. The cost of installing an RSJ can range from £1,600 to £2,200, this can vary depending on the size and type. It’s important to consult with a structural engineer to determine the appropriate beam for your project.

When selecting a beam, consider factors such as load requirements, span length, internal or external wall application and how it will integrate aesthetically with the existing structure. Accurate calculations are critical, as any errors can lead to significant structural issues.

Open Plan Living: DIY vs. Hiring Professionals

Removing a supporting wall can be a complex task thats best left to experienced professionals. While a DIY approach might seem cost-effective, you’ll have to coordinate various trades, which may turn up late or be delayed themselves, leading to complications like miscommunication or delays. Hiring professionals simplifies the process, as they manage all necessary trades, ensuring a smoother workflow.

Choosing a professional contractor can lead to time savings and a more efficient project completion. Professionals ensure safety and success, helping you avoid long-term costs associated with improper removal, they can usually complete the project in a timely manner with the least amount of disruption.

Benefits of Removing a Load Bearing Wall

Removing a load-bearing wall can significantly increase your living space, making your home feel larger and more open plan creating additional uses for your rooms. This transformation creates a more spacious and airy atmosphere, aligning with contemporary living preferences.

The removal process can also enhance the distribution of natural sunlight within your house, resulting in a brighter and more inviting interior. Open-plan living layouts are often sought after in the property market, which can elevate your kerb appeal and potentially increase its value, opening up new possibilities for more open space design.

Building Regulations and Party Wall Agreements

Understanding and complying with building regulations is a must for the safety and legality of removing a load-bearing wall. Building regs approval is required for any work on load-bearing structures to ensure safety and compliance. A party wall agreement is necessary when the property has a shared wall with a neighbour. The Party Wall Act provides a framework to prevent and resolve disputes regarding party walls. Complying with this act is crucial to avoid conflicts with neighbours and ensure a smooth renovation.

Summary

Removing a load-bearing wall can transform your home with open plan living, making it more spacious and inviting. However, it involves a complex process that requires careful planning, professional consultation with a structural engineer, and adherence to building regs. By understanding the steps involved, the costs, and the potential risks, you can ensure a safe and successful renovation. If you choose to hire professionals or take on the project yourself, being informed will help you make the best decisions for your home. Embrace the transformation and enjoy the benefits of a more spacious and modern living space. View our other articles for design tips.

Strategic Benefits for Class e Commercial Business Design

Class E empowers architects to design flexible, future-ready spaces. Buildings can be tailored to suit several commercial business and service uses over time, from retail warehouses to indoor sport facilities and professional services. As architects we need to design and plan ahead to keep the space adaptable to change across business or service locality needs. For example:

• A retail unit becomes a medical clinic
• An office transforms into a fitness centre
• A service locality includes both a café and professional workspace

This supports community resilience and aligns with sustainability goals by encouraging reuse rather than replace.

Limitations and Special Cases

While Class E is generally quite broad, some activities are excluded, including:

• Hot food takeaway and drink principally for off-premises consumption
• Activities involving motorised vehicles or firearms
• Non residential institutions like state funded schools and hospitals

Some uses like internet cafes, post offices, funeral directors, and pet shops do fall under Class E, but may still require detailed review depending on local authority policies. Historic buildings usually come with slightly more red tape and may need listed building consent, even if the use stays within the same class.

Revitalising High Streets with Use Class E Commercial Designation

Use Class E commercial flexibility is a real advantage for high street regeneration. By cutting down vacancy rates and encouraging mixed-use developments, it creates vibrant, dynamic environments where health clinics, retail shops, and food and drink venues can all thrive side by side. Designers, builders and architects have an exciting opportunity to reimagine these spaces. We focus on how operational or administrative functions flow, how the visual identity supports the community, and how internal adaptability can future-proof designs, the goal is that our projects remain practical, welcoming, and compliant with planning regulations for years to come.

Budgeting for Your Extension

Budgeting is vital. Include all costs such as materials, labor, permits, unexpected expenses, and a 10% contingency fund for unforeseen costs (sometimes 10% isn’t enough). Factors like size, location, materials, and build complexity affect extension costs, which typically range from £30,000 to £140,000 for single-storey extensions and £1,800 to £3,000 per square meter for side extensions. To save money without compromising quality, consider hiring an architect, reusing fixtures, and buying second-hand items. Choosing low-maintenance materials also helps reduce unexpected costs and keeps your project cost-efficient.

Construction Process for a 3 Meter House Extension

The construction process is the most significant step in your house extension project. Hiring a qualified professional ensures the quality and compliance of the work. While DIY projects can be tempting, they carry risks of substandard work and much higher costs to fix issues.

The typical timeline for completing a 3 meter house extension ranges from 3 to 6 months, depending on the complexity and any unexpected challenges that may arise. You just don’t know what you are going to find when you start digging out foundations! Let’s explore the different construction methods and how to select durable and stylish materials for your extension.

Choosing the Right Construction Method

Common construction methods for a include:

• Brick-and-block: Traditional appeal and good insulation
• Timber frames: Quick to build!
• Pre-cast concrete panels: Modern, speedy construction
• Modular extensions: Constructed using prefabricated modules
• Structural insulated panels: SIP panels

If you choose to manage the project yourself, you’ll need to direct on-site work, liaise with an architect, and handle the planning authority, this does take up a lot of time and is difficult if you have a full time job, expect some early mornings and late nights.

Selecting Durable and Stylish Materials

Selecting the right materials for your project is crucial for durability and style. Recommended materials include:

• Concrete, wood, and metal for their strength and aesthetic appeal.
• Brick, which offers excellent insulation and blends well with traditional homes.
• Timber cladding, providing a natural, stylish look.

Composite materials like fibre cement board can be rendered to make them extremely durable, weather-resistant, and low maintenance, making them a practical choice for extensions. We would advise taking the time to learn about material choices, by choosing materials that match you current property, meet specific criteria for durability and aesthetics, you can ensure your extension stands the test of time.

Finalising Your Extension

Finishing your 3 meter house extension means ensuring the space is functional and complies with local planning authority regulations. Obtaining a Lawful Development Certificate (LDC) proves your extension was completed legally, helping when selling your home. Compliance with building regs covering ventilation, fire safety, and heating is essential to make your home habitable. The satisfaction of enjoying your new space makes the effort worthwhile. You may also need a new  EPC (energy performance certificate)

Communication, Final Inspections and Completion

Communication with your contractor is key to staying updated on progress and timeline changes. Building a 3 meter house extension usually takes 3 to 6 months. Moving out during construction is advisable if you can. for comfort and less stress, but if not possible, a sealed work area can really help separate the work from daily life and minimise dust! Final sign off inspections confirm your extension meets all standards and must be completed before contractors leave, ensuring the space is safe, functional, and compliant.

Permitted Repairs and Maintenance

Major alterations require consent, but general maintenance and minor repairs typically do not. Routine inspections and timely repairs are essential for historic building upkeep, preventing issues that could compromise structure and historical value.

Using compatible original materials is crucial for maintaining a listed building’s integrity during repairs, especially when exposing timbers. Old building materials generally don’t react well when matched with modern day materials, incorrect material can harm the building and lead to consent refusal, making professional help advisable for compliance with conservation standards.

Many owners mistakenly assume minor repairs do not need consent, leading to legal issues. Consulting local authorities or a conservation officer will help avoid unauthorised repair work and its consequences. It is wise to seek advice to ensure compliance with regulations, we would not advise moving forward without it!

Working with Conservation Officers

Engaging with local conservation officers early can ease the process of obtaining advice and the necessary permissions. They provide invaluable guidance on permissible alterations and help navigate complex regulations, ensuring modifications align with the building’s historical and architectural significance within in the land.

Conservation officers collaborate with local authorities to offer expert advice on historic preservation during planning applications in a conservation area. There main aim is to preserve the unique character of listed buildings while allowing necessary updates and essential repairs, ensuring a smoother, compliant renovation process for owners.

How to Avoid Common Pitfalls of Listed Buildings

Navigating regulation can be fraught with pitfalls. Local planning authorities can issue a listed building enforcement notice for unauthorised work, requiring restoration to the original condition. Listed building restrictions, regulations make seeking professional advice and ensuring compliance with regulations essential to avoid this.

Differing interpretations of strict rules by local conservation officers can lead to misunderstandings and delays. Clear communication and early consultation with relevant authorities are key to avoiding these pitfalls, aligning work with guidelines, and preventing costly mistakes in a speedy process. You must understand that unauthorised works to a listed property can be enforced indefinitely.
