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.

Restoration & Refurbishment- 26 Jun 2022
Tommy was a wonderful perfectionist and has done beautiful work in our stairway and hallway which had needed refurbishment for a very long time. It feels brand new. The flooring is perfect both in the hall and staircase, and the walls are now perfectly smooth and painted immaculately. Friendly and accommodating, we will be hiring again for more jobs in the future, undoubtedly. Thank you.

Extensions- 13 Oct 2023
Sagar and Sanjeev are incredible- they are very diligent and really well versed in what they do! They know what they are talking about and are very friendly and incredible to work with. There was no issue that they weren’t able to help me through when it came to a complete renovation, extension and garden landscaping of my house. They are experts in what they do and they’re the only contractors I want to work with for any other works in the future. Would always recommend them. 100/100!

Tiling- 11 Jun 2025
I hired for just for bathroom and toilet tiling, However due to the diligence, attention to detail, honesty and work ethics of Muro construct, I hired him to decorate my entire house, this includes everything form stripping wallpaper and painting, floorings, tiling, fixing doors, putting up all my new furniture including a very compl bunk bed for my children room. This builder works really hard and time efficient. He has helped transform my house into a luxurious living space and I am not exaggerating when I say that the price is very fair, I have had three times the quotes for less the quality. I will be using the builder for future jobs.

Extensions- 23 Dec 2022
ELB Construction completed some major garden works for me and constructed a garden office. It was a big piece of work with a lot of earth moving, significant foundations and a lot of brickwork. The ELB team, specifically Jimmy the site manager, were fantastic, always giving me the right advice about things I was not knowledgeable about, always focussed on a quality finish and flexible when we had some challenges with our neighbours. The finish is great, communication was always open and honest and they were very competitively priced. My brother in law is in corporate construction and was specifically very impressed with the quality of the brickwork that Jimmy and the team produced. Thank you to the whole team!

Latest review:
We initially hired Michael to convert a bathroom into an office. After meeting him and discussing our longer-term plans, we quickly felt confident moving forward with him on much wider renovation works across the property. Michael worked closely with us throughout the entire process—from early ideas and structural planning through to execution. He consistently provided insightful, practical advice that added real value. His ability to anticipate issues early not only prevented problems but also helped us save money by refining the plans to maximise our goals and avoid unnecessary costs. Michael’s broad knowledge and skill set were hugely beneficial on a project of this size and within a tight budget. He made the process far less stressful and, at times, genuinely enjoyable. He kept me informed and involved at every stage, which gave me a great deal of confidence in both the quality of the work and the decisions being made throughout. Michael helped us renovate every corner of our four-bedroom maisonette in West London—from bathrooms and structural opening-up works to a full kitchen renovation, hard landscaping, flooring, and carpentry. The list goes on. His wide skill set and depth of knowledge were truly impressive and exactly what we needed, particularly as we chose to stay closely involved in the renovation rather than hiring a larger construction and project management company. We genuinely don’t feel we could have made a better choice. It’s not always easy to find a builder who is reliable, honest, and trustworthy, so I feel very fortunate to have worked with Michael. I would recommend him without hesitation and will absolutely continue to work with him on future projects, big or small.

Gavin built me an outhouse at the bottom of the garden. The work was tidy and efficient and the result just what we agreed. This involved brickwork, carpentry and electrics, and all was done to a good standard and in a reasonable timeframe, even despite the snow! I would recommend Gavin to do this sort of work and would use him again if needed.

Kitchen Fitting- 24 Oct 2016
Kris, Gustav and their team have been absolutely amazing, cannot praise them enough. First of all - the job ended up being a lot larger than initially thought- as decided to replace old ceilings and flooring, walls -everything was uneven to start with. So took everything back to 'bare bones' and pretty much built it up again as a new house. New electrics, water pipes, completely new kitchen and bathroom. I really appreciate they were very straightforward with the estimated costs from the beginning - it did run slightly over budget but nothing too bad as had some contingency funds prepared. I would have hated to be quoted one price then half way through the project to discover it escalates out of control. Thankfully they are really honest and reliable. They were always easy to reach and replied any question I might have had in a timely manner. This was particularly important to me as I was between uk and us at the time so couln't be 'looking over their shoulder' so to speak. Last but not least the finish and quality of works is absolutely amazing! They couldn't have paid more attention to every little detail if it was their own home. For instance I remember last day of work when they were tidying up Gustav came back to put up door stoppers for me, completely on his own initiative. It's just a little touch but goes to show the dedication they've put into the project and care about the finished product.

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

What experience do you have with similar extensions in Camberwell?
