Haxhi and his team exceed my expectations. We did agree on a bathroom renovation which basically everything was done from scratch. He was always on time and he met the deadline of the project. I had an issue with my water pump but he managed to fix it for little cost. Also he did the tiles for me on the wall and floor with very minimum waste and he did a brilliant job. We changed the position of the basin in order to save space and we did replace it the washing machine(hidden). We are now working on my other property to renovate the bathroom. Hahxi is very professional, knows the job very well, he did coordinate with me on every step to make sure we are on the same page . I strongly recommend him for any renovation project you may have.

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.

Landscaping- 4 Oct 2024
One word to define this 'company' COWBOY builders. Numerous issues one after another. Had to get 2nd/3rd opinion on their work to make sure I wasn't being fobbed off. Conducted loads of research which meant left being uneasy especially as a large chunk of payment was made after only 1 day of work when in fact payment was due end of completion. 1- Underestimating material costs 2- Slabs off the walkway coming loose within 2 months of being put down 3- Ignoring attempts of rectifying the flawed job 4- walkway was meant to be clear of grass and strictly shingles but grass/weed still appearing. 5- Forgot to state ground levels would be raised then creating a lie saying I had been told 6- denying and ignoring the obvious Wouldn't trust the reviews being left here and definitely wouldn't use or recommend them to anyone. Have decided to give up on trying to get them to fix their shoddy job and find someone else to fix their mess Correction - you was aware & agreed with mat delivery

Extensions- 11 May 2016
Really happy with the work Paul and his team did on our extension. They were quick, neat and tidy throughout and kept us updated at each stage. There were some early design changes which building control insisted on and they were happy to adapt to the new plans without fuss. We couldn't believe how quickly it was all finished and the standard of work was very high too. Would definitely hire again if we ever need to.

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

An extension builder in Knightsbridge 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.

Will my home extension meet all building regulations and planning requirements?

What experience do you have with similar extensions in Knightsbridge?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Knightsbridge extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.
