I engaged Edi to work on a full renovation and refurbishment of a 4 bedroom detached house with front and back gardens on Blackheath’s Cator Estate. Edi did an extensive amount of work, including stripping out; plumbing; plastering; windows installation; carpentry; and decoration. In addition, after commencing the property work, once the scaffold had been erected, following sensible advice, Edi and his team replaced the roof and fully insulated the attic; fitted additional electric points; rebuilt the garden patio; and replaced the flooring throughout, in addition to other important jobs including re rendering and pointing of chimneys, building new wardrobes in the main bedrooms; and upgrading the radiators. A new kitchen, and two new bathrooms have been fitted. The kitchen redesign meant knocking through a wall with the lounge to create a larger space. Edi is a highly skilled craftsman, who thinks creatively as he works to make best use of the space, including shelf fittings, and additional lighting for example. He has built some beautiful wardrobes, and the internal decorations have brightened up what was previously a rather shabby looking house. In addition to the above, I wish to commend Edi for his professionalism, courtesy, and passion for doing the best work possible. On all the site visits I attended, and every time I spoke with him on the phone, it was striking how much he cared about the work that he was doing, his desire to ensure that the house would look the best. I always left site visits with the feeling that he cared so much about the house that he could be safely relied on to give the best advice to enable us to make the right decisions. I also noticed that Edi and his team would take the upmost care to keep the property safe, tidy and in good shape throughout the project. He can be fully trusted to look after any site he works on. He is intelligent and careful when it comes to safety and security. It has been a pleasure for Edi and his team to work with us over a period of around 6 months, and he did so much to reduce the stress of a significant project so that we could always rely on him to work methodically, patiently and sensibly, and to make best use of the resources available. His pleasantness shines through, and everyone I know who has spoken to him has always provided me with the most positive feedback I have no hesitation in recommending Edi to anyone who wishes to engage him for future projects, and is most deserving of the good words that I and others that work with him have to say about him.

Painting & Decorating- 12 Feb 2019
He truly showed professionalism that I had struggled as a guest house operator to get from handy people. He would go out of his way to satisfy. The finished redecorated room project was a masterpiece and took a little longer than planned because of the weather but he gave it his all! I am pleased I took a chance on him as there was no review on his profile when I hired him. I would however, pay attention to work and point out issues as they come up otherwise, you will have dirt and rubbish to content with as the workers leave all the mess after work.

Restoration & Refurbishment- 25 Sep 2025
We were over the moon with our kitchen once Zihni and his team had finished. We had never used this firm before but we will definitely be using them again for future projects. Zihni is calm, knowledgeable, and went over and beyond in helping us not just complete our kitchen project, but in helping us move into a new home smoothly. We are also really appreciative of the rest of his team, as they were all so serious, professional and perfectionists. Zihni's communication was probably the single reason why the completion of our kitchen was such a success.

Carpentry- 24 Jan 2021
George came to do up our hallway. He laid flooring and installed new spindles and a handrail on our stairs too. He did a wonderful job on the whole lot and we were very happy with him. We were awkward and changed our mind on the first laminate flooring that I had picked out online, he ripped it up and started again with the new flooring we picked and it was no hassle to him. George is a lovely fella, trustworthy and professional. Would highly recommend

Fencing- 3 May 2022
Mario is an excellent fencer. He priced my job quite reasonably, it was more practical to change to whole fence than to fix a few existing posts, as when we pulled them out they were all rotting. He was careful whilst bringing materials through the house, and also looked after my plants and exercised care to them whilst digging and erecting the posts and fence. It was a pleasure having him do the job, professionally and with great care. I would recommend him and his team for similar kind of work.

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.
