Benny and his team completed our loft conversion in 2022 and we've been very happy with the work carried out. From the beginning of the quote process through to completion, Benny and his team were extremely professional, hardworking and reliable. The work was finished on time and as quoted. Benny was happy to offer advice on what we were looking for and adapt elements as we progressed. The quality of the work was excellent and his team are clearly experienced and thorough.

Extensions- 11 Jan 2018
This was our first project, and we were exceptionally fortunate to find Bujar. We're actually getting tired of hearing our family and friends tell us how lucky we are and how amazing he sounds. One of the most honest, trustworthy, and genuine people I've ever met. If I had a problem, he'd be one of the first people I'd call! In fact I did last week and he came to the rescue :) His team were all friendly, polite, conscientious and very tidy. They worked around us as much as they could, always making sure we had access to what we needed which sometimes meant it took them longer to work. Bujar is a perfectionist and is so proud of what he does, he made sure everything was done to a high standard - the estate agent who came round after we were done was impressed! His prices are very fair (better value than other quotes we got and much less time). We couldn't believe it was done in the 3 months he said it would take, and we managed to fit in a few extra bits and pieces after that. He was so helpful throughout, took all project management on and didn't bother us unless an important decision needed to be made. He drove us around all over the place to sort kitchens, bathrooms, etc. and gave us really helpful advice throughout the process. Highly recommend him and his team. I can't imagine ever wanting to look for another builder unless I had to - something that is quite common amongst Bujar's clients. We are extremely pleased with everything about our new house.

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.

An extension builder in Grange Park 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?
