We recently used SG Construction for our home extension and we couldn’t be happier with the outcome. From the initial quote through to completion, the whole process was handled professionally, The team were reliable and really hard working. Communication was excellent throughout, and we were kept informed at every stage of the build. The quality of workmanship is outstanding and the attention to detail really shows. They kept the site tidy, minimised disruption as much as possible, and were respectful of our home and neighbours. It’s clear that SG Construction take real pride in their work.

Extensions- 18 Jun 2026
Honestly cannot recommend these gentle giants enough, we had they most amazing time renovating our home home with Luke, Jerry and the team. As first time buyers, with no family in the trades, we were nervous to find a builder and get started but from the second they stepped into our home they bought into the vision and helped guide us through it. At no point did anyone make us feel like we were in the way or asking a stupid question, they helped us learn about the process and kept us in the loop at every stage. We had so much fun working with everyone and cannot wait to be calling them back again. (p.s they really love a jam doughnut)

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.
