Ivan and his team completed a full loft conversion at our terraced house, and we couldn’t recommend them more highly. They did a fantastic job from start to finish and were a pleasure to work with. Communication and project management throughout the project was excellent, and their commitment really showed. Nothing was ever too much trouble to ask. The project was completed within the estimated timeframe, which was especially appreciated as it finished just before Christmas. The team was very considerate while working in our home, and we stayed in the house for the entire duration of the project with minimal disruption. In addition to the loft conversion, they also replaced all our doors with fire doors and installed new flooring throughout the house, all to a very high standard. We’re absolutely delighted with the results and would highly recommend Ivan and his team to anyone considering similar work.

Restoration & Refurbishment- 22 Nov 2023
I had an out door room in my garden put up by some cow boys which I was left with needing a multitude of problems fixing. Our budget was quite tight but Pano provided us with quotes for each stage of the job detailing what was included in each stage this was really helpful. Pano was great at discussing and suggesting best ways to find solutions understanding our budget we never felt pressured to spend more. We trusted his guidance in the best way to complete the work. Pano always turned up when he said he would and at the end of each day left areas clean and tidy. Now the job has been completed we have the out door room we wanted and are really happy with . I would absolutely recommend him to anybody looking for a builder and would contact him again for further work . Thanks again 😊

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!

Extensions- 28 Oct 2018
We appointed HWB to carry out a full refurbishment on our house, this involved re-gutting the interior and building an extension and loft conversion plus some landscaping in the garden. We spoke to many builders but finally appointed HWB based on their previous projects and professionalism. Appointing builders for any work is always difficult however we are delighted that we went with HWB. Throughout the project they have demonstrated high levels of professionalism, were very organised and worked to very high standards. They were collaborative throughout the whole project and kept us informed at every stage. As the project developed there were some changes made and HWB were flexible and open to new instructions made by us, as well as giving us valuable advice. Farag, Ayoub and the HWB team were always available to answer any questions and provided us with constant feedback on progress as well as identify new solutions to aid the development. They have a great team of workers who work to a high standard and are supervised throughout the project. We made the right decision going with HWB Construction and have no hesitation in recommending them.
