What Our Clients Say
Thank you to Amol and his entire team
“Thank you to Amol and his entire team for delivering us a fantastic extension to our newly purchased home. The guys were friendly and very professional during all stages”
Lisa
Twickenham TW2
Thank you Good Design & Build…
“Originally, we’d planned on this being a property to rent out to others. Since the loft conversion, we’ve fallen back in love with the place – and have now decided to move back here.”

I would like to thank GDB…
“I would like to thank GDB for all of their hard work, ideas and inspiration and for being so approachable and easy to deal with during the our rear extension. I would happily recommend them to anyone thinking of starting a building project”
Debra

My wife and I would like to say a huge thank you
“My wife and I would like to say a huge thank you to all the team at Good Design & Build. From the planning stage all the way through to completion they were meticulous with their design and helping us achieve our vision of our dream family home. We were supported all the way through, even when we wanted to make significant structural changes during the build. We are over the moon with the results achieved and quality of the building work and finishing is excellent. THANK YOU GOOD DESIGN & BUILD!!”

Good Design provided the architectural services
“Good Design provided the architectural services as well as building work. It was great to have both bundled into one. They were very flexible and great to work with - nothing was too much trouble. I would highly recommend them.”
Louise Murray

We thoroughly enjoyed working with Amol
“We thoroughly enjoyed working with Amol and the Good Design & Build team on our recent house extension. We've been so happy with how the team helped design, plan and deliver the extension. Always very patient and informative of how the process will run, the team did a fantastic job and we're delighted with the results. The biggest compliment I can give them is that I'd happily work with Amol and the team again :).”
