Extensions- 9 Apr 2019
Jason did a great job with our rear house extension. Very hard working, kept us informed all the way. Really knowledgeable and was helpful in suggesting improvements and different ways to make the extension work the way we wanted it to. Great attention to detail throughout, our new kitchen looks great, makes a massive difference to our home. Brickwork, plastering all spot on as well. The whole process was really smooth with very little disruption. Would definitely recommend Jason. Great builder and an all round nice guy which shows in the quality of work and the finished product.

The final product is great and we are very please. The attention to detail, finish and general workmanship was great. They also did well dealing with an old build which is anything but straight. We would use them again and recommend them to others.

Extensions- 17 Aug 2021
Long overdue feedback, the pictures/ decor has changed since below but just wanted to share the feedback. Crew are super, we’re with us through pandemic and worked tirelessly when materials were short and jobs were delayed.. simon is a fair guy, busy but still gives you time to share his creative side. Nothing was too much of a bother. Workmanship is A* and I have huge OCD. I would recommend Simon and team to anyone. And we spent a fair amount of money, everything was reasonable priced with no surprises. With Covid, the whole team were mindful and with a short delay due to restrictions got back on track.. every single one of the team were nice/ hard working and rarely do you find a team that can do the demolition yet have the finesse of the final touches. Sorry for the delay in feedback..

Extensions- 31 Dec 2025
Rae and his team were excellent from start to finish. Always reliable and polite they completed a wrap around extension within the predicted 10-12 weeks and on budget which was faster and cheaper than anyone else we spoke to. Throughout the project Rae was organised and constantly communicating the progress, any snags and when things needed ordering. The finish of the work is top notch and they were amenable to carrying out extra bits of work along the way and quickly sorting any problems that arose. We would not hesitate to use them again or recommend them to friends and family.

Landscaping- 29 Jun 2025
Really pleased with the work that Kallum did for us. He moved our shed and removed the concrete base for us. He was quick to respond, reliable, gave us a good price and did a great job. We actually invited him back to board our loft a few days later! Would definitely recommend and hopefully he will help us out with other jobs in the future.

We have been very impressed with Robert. We hired him for our new bathroom installation and we ended up using him for almost the entire project. He is honest, knowledgeable, conscientious and passionate about his job. The bathroom was perfect and even other trades men were impressed about his attention to detail. We have recommended him to all our friends and family. I'm so pleased I chose him for our job. I'll certainly be using him for my extension.

What qualifications and experience do you have as an extension builder in Brighton?

An extension builder in Brighton should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your Brighton extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Brighton?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Brighton extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Brighton extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
