Conversions - General- 10 Nov 2024
I recently had the pleasure of working with Empire construction for a renovation project where we moved my kitchen into the living room to create an open-plan space and added a spare bedroom. From start to finish, the experience was fantastic! Communication was excellent; Perry was always on time and made me feel comfortable having him and his team in my home. They worked quickly and efficiently, delivering a high standard of workmanship that I truly appreciate. The recommendations they provided were spot-on and really helped enhance the overall design. I love my new kitchen & highly recommend them to anyone looking for quality renovations.

Extensions- 4 Jan 2026
I hired Amrit based on positive reviews, but my experience was extremely poor. The work showed all the signs of a cowboy builder. I’m sharing this to help others avoid the stress, delays, and financial risk I went through. 1: No Respect for Contract or Deadlines Contract deadline was 15th September, which he completely missed. Despite delays, he demanded money almost daily. When I referred him to the payment and work schedule he signed, his response was: “I didn’t read it, I just signed it.” 2: Dangerous and Unprofessional Working Practices Brought in unqualified workers, many of whom could not speak basic English. He ignored safety standards throughout the project and wanted to use the same unqualified workers for gas work, which is extremely dangerous. When I objected, his response was: “Don’t worry, you will get a new house if it blows up as you have insurance.” 3: Work failed multiple building control inspections. He eventually refused to cooperate with the building inspector.

Extensions- 24 Jun 2017
We had a large piece of work done by Johan and his team. It was a 4m single storey rear extension with new kitchen installation, converting the old kitchen into a downstairs bathroom and utility room, plus other bits and bobs like new boiler, rear patio. We got quotes from a few builders, Home Renovations weren't the cheapest, they were actually towards the higher end. But we went and saw their previous work and spoke to some of their other clients. The work was done to a high quality and the clients seemed to be happy so we decided to go with them. Johan's team are very hard working, professional and polite. Pawel and his team of builders, bricklayers, plumbers, electricians, etc. would turn up before 8am and finish at 6pm working solidly throughout the day. There is Magda as the project manager who keeps you in the loop, and answers any of your questions (which we had many). There is Michaela on the finance side who keeps you up to date with the budget. Our budget went over by 5% with "variations" (extra work or materials) but it was always communicated why and the work wasn't done without our approval. Pawel would give his recommendations but the final word would always be ours. But these things can add up. Overall we were very happy with the build, it was done to a very high standard. They also finished it before time. They said it would take 12 weeks in fact they finished it in 10 weeks which was amazing as you would normally expect these things to go over.

Landscaping- 18 May 2021
Joe was professional and responsive for my posted job to do fencing and wood trim repairs. He was able to provide a quote quickly and did the work in quick fashion. I wasn't quite sure what was feasible, but Joe was able to provide good guidance on what could be done for the repairs. The quality of the workmanship seems to be high, and I am pleased with the result. I would definitely recommend Joe for this type of work.

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

An extension builder in Thames Ditton 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.

What experience do you have with similar extensions in Thames Ditton?
