How Much Does an Architect Cost for an Extension in the UK?

At Trimble Architects, we provide detailed cost estimates based on your specific project requirements, ensuring that there are no surprises along the way.

On average, the cost of a rear extension in London can range from £40,000 to £70,000, depending on the size, design, and materials used. For larger projects, such as double-storey extensions or loft conversions, the costs can be higher. However, working with a skilled architect can help you save money in the long run by ensuring that the project is completed efficiently and to a high standard. Architects can also help you obtain discounts on materials, and their expertise ensures that the design is both functional and aesthetically pleasing, adding value to your property.

At Trimble Architects, we recommend discussing your budget with our team during the initial consultation. This allows us to provide you with a clear understanding of the costs involved and ensure that your project stays within budget. We also advise setting aside a contingency budget of around 10-15% to cover any unexpected costs that may arise during the project.

Whether you're planning a small single-storey extension or a larger two-storey extension, we are here to help you every step of the way, ensuring that your project is completed on time, on budget, and to the highest standards.

Planning a house extension can be a complex and challenging process, but with the right architect by your side, it can be made much simpler. At Trimble Architects, we guide you through every stage of the planning process. From initial design and planning to obtaining planning permission and building regulations approval. Our architects will work with you to determine the best design for your extension. Whether you're adding a rear extension, side extension, or loft conversion, we will ensure that your project complies with all necessary regulations and requirements.

One of the most important factors to consider when planning a house extension is your budget. It's essential to have a clear understanding of how much you're willing to spend on your project, including the costs of materials, builders, architect fees, and any additional features such as solar panels or modern kitchen fittings. We recommend setting aside a contingency budget to cover any unexpected costs that may arise during the project. Our team can provide you with detailed cost estimates and help you develop a realistic budget that ensures your project stays on track financially.

Another key consideration when planning your house extension is the impact it will have on your neighbours. If you're planning a side or rear extension, it's important to discuss your plans with your neighbours early to avoid any potential disputes. Our architects can help you navigate the legal aspects of the project, such as party wall agreements and boundary considerations, ensuring that your project proceeds smoothly and without conflict.

We also provide advice on how to minimise disruption to your neighbours during the construction process, ensuring that your project is completed to the highest standard while maintaining good relationships with those around you.

DO YOU NEED PLANNING PERMISSION?

In many cases, house extensions can be built without the need for planning permission under permitted development rights. These rights allow certain types of extensions, such as single-storey rear extensions and loft conversions, to be built without the need for a formal planning application.

However, it's essential to check with your local planning authority or planning consultants to ensure that your project complies with all necessary regulations. At Trimble Architects, we provide expert advice on permitted development rights and can help you determine whether your project requires planning permission or if it can proceed under these rights.

For larger projects, such as double-storey extensions or loft conversions, planning permission is often required. Our architects will guide you through the entire planning application process, ensuring that all necessary documents, drawings, and plans are submitted to the local council for approval.

We work closely with planning officers and local authorities to ensure that your application is processed efficiently, allowing your project to proceed without delay. Whether you're planning a single-storey rear extension or a larger two-storey extension, our team will ensure that your project complies with all legal requirements and is approved by the relevant authorities.

WILL IT IMPACT YOUR NEIGHBOURS

Building an extension can have a significant impact on your neighbours, particularly if the project involves major changes to the exterior of your property. For example, a rear extension or side extension could block natural light in your neighbour's garden or windows, affecting their quality of life.

It's important to consider these factors when planning your extension and discuss your plans with neighbours early on to avoid any potential disputes. Our architects can help you navigate these issues, providing advice on how to minimise the impact on neighbours and ensuring that your extension complies with local planning regulations.

If you're planning a larger project, such as a double-storey extension or loft conversion, it's essential to be mindful of how the construction process will impact those around you. Noise, dust, and disruptions to daily life can all be factors to consider, especially if you live in a densely populated area.

At Trimble Architects, we work closely with you and your neighbours to ensure that the construction process is as smooth and stress-free as possible. We can also assist with legal aspects, such as party wall agreements and boundary disputes, ensuring that your project proceeds smoothly and without conflict.

ARE YOU IN A CONSERVATION AREA?

If your property is located in a conservation area, there may be restrictions on the types of extensions you can build. Conservation areas are designated to protect the historic and architectural character of an area, and local councils often have strict guidelines on what changes can be made to buildings in these areas. If you're unsure whether your property is in a conservation area, we recommend checking with your local council or planning consultants to ensure that your project complies with all necessary regulations.

At Trimble Architects, we have extensive experience working on projects in conservation areas and can help you navigate the planning process to ensure that your extension is approved. Whether you're planning a small single-storey rear extension or a larger two-storey extension, we will work closely with you to ensure that your project complies with all local regulations and enhances the character of your property. Contact us today to discuss your extension project and how we can help you achieve your goals, even in the most restricted areas.
