We’ve worked with residential architects before, but Jamie and his team, especially Nathan, were fantastic. Kirkwood designed plans for our double-story side extension, loft conversion, and single-story rear kitchen extension, and we knew we had to choose the right company since it involved our entire home.

Based in Brentwood, Essex, we were also introduced to builders and tradespeople through Kirkwood, and they were excellent—professional, respectful, and a pleasure to work with. If we ever take on another project, we wouldn’t hesitate to use them again.

Kirkwood done a fantastic job on our architectural plans for our new single story kitchen extension in Brentwood. They gained us approval from the council and also provided the structural engineering for the project. We used their recommended builder who so far, we cannot fault one bit. Thanks again and highly recommend.

The Kirkwood team were a pleasure to work with and have in our house. What can be a stressful time was made a lot easier by a team who build with quality, communicate clearly, and address and action any questions you raise....however small or large.
We now have an amazing extension, and would be happy to use the team again.

Kirkwood Design and Build Builders, Wickford did a fantastic job on our extension in Billericay. They helped with planning permission, design, and build. Professional company through and through. Given that we haven't done such a large project before, we were a bit nervous and had a lot of questions. Jamie and his team from Kirkwood Design and Build Builders was good putting us at ease and now that we are fully complete with all our work, we further appreciate how professional this company is. Would highly recommend.

    It depends on the size and type of extension. Many single-storey rear extensions fall under permitted development, meaning full planning permission may not be required. However, even in these cases, you’ll usually need to apply for a Lawful Development Certificate to confirm the work is legal and approved by the council. Larger builds or homes in conservation areas typically require full planning approval. We offer free expert advice to help you understand exactly what’s needed for your project in Grays.
