Rob and his team did an exceptional job converting my garage into a beautiful utility and w/c.  Nothing was ever too much trouble.  The team's attention to detail was amazing.  The space was not easy to work with and they created bespoke solutions which fit our requirements beautifully with high quality craftsmanship.  Highly recommend Thames Design & Build, and will be using again for future projects!

Garage Conversion

Designed and built a wrap around kitchen extension, installed a toilet and new bathroom and took out a chimney. V pleased with the work and all who worked on the job - friendly and professional throughout and mindful of our neighbours. Different specialists worked seamlessly together from our perspective. Our foreman was exceptional in pulling the whole thing together - solution and customer- focussed.  Contract and quote were very professional and transparent. Only variations were ones we expected or resulted from choices we made.  Communication was great throughout. All finished on time too.

Professional, high quality work, transparent pricing, finished on time, friendly

Design ideas were thoughtful,creative and they really took time to understand what I wanted.What really stood out was their attention to detail and the care they put into the quality of the build.Everything was within budget and the team were respectful, tidy,nothing was too much trouble and they were a pleasure to have around during the work.The finished extension is beautifully constructed and blends perfectly with the existing property,both in style and function.
I would definitely recommend Thames Design and Build and I’m genuinely delighted with the outcome.

Side extension 

We had a great experience with TDB! We’re 4 years on and still in love with our extension. Rob and the team were so attentive and organised which was great as I was having my first baby at the time of the build but every detail was thought through and well planned! 

Side return extension 

Fabulous job from Thames Design and Build. Delivered my kitchen extension on time and on budget. Rob did a marvellous job keeping everyone organised and the individual contractors were courteous and top quality.  Couldn’t be more pleased with the end result.

Thames Design and Build were a friendly, professional and committed company, working to the highest standards. We had a single storey ground floor extension and new veranda. We were delighted with the results and we would have no hesitation in giving a strong recommendation.
