Highlights
"GSW did a superb job . There time keeping was excellent , workmanship first class and all delivered in a pleasant and helpful manner . When minor unexpected problems occurred they always had good practical ideas. They protected the house from dust as best they could and cleaned up ery night before finishing ."
"I couldn't be happier with the incredible work that Gavin did on my office space. From the very beginning, he was professional, communicative, and happy to help with advice to rennovate a non-functional space. The project was not without its challenges, but Gavin consistently went above and beyond to find solutions and ensure every detail was perfect. He was always on time, kept the worksite tidy, and completed the project to a high standard within the quoted timelines and budget. He's transformed the room, and I'm so grateful for his hard work and expertise."
"From the first visits to quote to the final checks Gav was brilliant- extremely knowledgeable, hard working, reliable, tidy and friendly. As well as doing the bulk of the work himself (& team), Gav also managed all the extra trades needed to complete the job making the whole project as stress free as possible for us. Works have been finished to a high standard and we're really grateful for Gav's advice and hard work provided throughout to ensure this was the case. We would highly recommend GSW building ltd for any project and would seek to use Gav and team again for any future works."

"Architect" is a title protected by law - only people on the official Architects Register (held by ARB) may use it. Confirm they're on it before you commission a design.
Check the Architects RegisterSmart checks
Before you hire an architect
Only someone on the Architects Registration Board (ARB) register may legally call themselves an 'architect' in the UK — ask for their ARB number and check it free at arb.org.uk. An 'architectural designer' or 'technologist' is a different, unregistered role (often capable, but not the same protection).
Agree how they charge before any work starts — a percentage of the build cost, a fixed fee, or an hourly rate — and exactly which stages it covers (concept design, planning application, building-regulations drawings, work on site), so there are no surprises later.
Confirm what they will actually handle versus what is excluded — the planning application, the building-control drawings, and whether they will administer the builder's contract on site — and get it, and a portfolio of similar projects, in writing.
Ask to see a portfolio of completed work like yours, plus recent references you can contact.
Check the credentials and registrations that matter for this work — and that they are current.
