Conversions - General- 15 Apr 2026
Luke and Diti are both amazing guys for this project. Honestly speaking they aren't the cheapest quote, but they are definitely beyond expectations. Luke was the only builder who gave a full transparent quote on each item and what was needed for the conversion. Really quick work and good planning because I have 2 cats and they did everything with enough people onsite to minimise the time. Speaking of work, it is good, we kept in communication and they were always happy to explain and adjust slightly according to my concern/question. Leave this comment after the work has been done for few months and everything is solid.

Plumbing- 18 Jul 2023
Ross has excited expectations in conducting the job I hired him for. The job consisted in locating and eliminating a bathroom smell, and he contacted the job successfully and at really affordable rates. The communication from the offset was timely, concise and clear. He visited my property once and tackled the issue, offering to come back free of charge in case the issue would persist. After his first intervention the smell nearly went away, but came back after a few days, way less prominently than originally. As promised, Ross came back free of charge and tried another solution, which solved the problem entirely. Throughout, I was impressed by his professionalism and efficiency. Highly recommended!

SSS BROTHER, They worked incredibly hard to transform our house in a timely and efficient manner, all whilst being responsive to our concerns and preferences.

Exquisite Design and Build recently reworked and refurbished our new, six bedroom detached house, having previously completed a kitchen extension at our last property. Andrei’s work is of an incredibly high standard. He shows great attention to detail throughout the entire process. Not only does he execute the work beautifully, but he offers great design ideas and and suggestions. With regard to contracting, pricing and invoicing, Andrei provides clear and accurate documentation which gives us complete trust in his ability to work within our budget. Andrei and his team are an absolute pleasure to work with; hardworking, punctual and tidy. I have recommended them to three other friends, all of whom chose to work with him on their extension/refurbishment projects and were equally delighted with the results. I would not hesitate to recommend Exquisite Design and Build to anyone, regardless of the size and complexity of their project.

Conversions - General- 12 Aug 2022
I hired HM construction for installing a built in cupboard in a bedroom to my specification. The team was able to knock down an internal wall, make good another wall and install an excellent built in cupboard. I am very happy with the outcome, it’s a highly professional job that has transformed the bedroom. Of the back of this I asked the team to install a porcelain tile patio, new turf and convert an outside shed into an Office space. They completed the work in just over 3 weeks again to an excellent finish and very reasonably priced. They ensured the site remained and clean at all times and kept me informed throughout the process. Very trustworthy and highly recommended constructors.

Conversions - General- 21 Jul 2023
We needed the dividing wall between our living / dining room removed and then replastered before our floor sanding took place, so timing (as well as quality) was very important to us. Rob promptly got in touch soon after I posted the ad and visited the property a few days later for an inspection and to talk us through the process. A week later the job has now been completed to an exceptional standard with plenty of time to spare. They were also well organised and did a great job minimising the mess that comes with removing a wall. We are very happy with the results so highly recommend Rob and his team for your future projects. Thank guys, James & Jade.

Added partition walls and a doorway to modify the entrance to our office area, creating a small meeting room. The work was completed to a good standard and at a time that suited us. Works were completed on time. The quote was 30% lower than what we paid in the end, but I think the result was worth the price.
