I received quotes from multiple builders to build a garden office, and choose Teodor as he provided the best quote. His workmanship is top quality and he built me a fantastic garden office which I am enjoying immensely. Teodor was very professional and reliable, keeping me involved throughout the whole project.

I recently hired Vithesh for a loft conversion, and I couldn't be happier with the results! He completed the project with exceptional quality and efficiency. The structural floor beams and steel structure were flawlessly installed, and the roof comes with a reassuring 10-year warranty. What impressed me the most was his ability to complete the structural job in just 3 weeks, even though the original estimate was 5 weeks. His commitment to meeting deadlines and delivering high-quality work is truly commendable. I’m absolutely thrilled with the outcome and will definitely be calling him for any future projects in my home. Thank you, Vithesh, for a job well done!

Loft Conversion- 22 Mar 2024
Glad we didn't hire him. After agreeing on a price for loft conversion and back extension, Mr Rattan kept increasing the price by referring to minor things. Like charging extra for plate that goes on steel. First day when he turned up, he demanded that owner should provide tea and snack for his labour every day. Also he was not ready to include the agreed price on the contract (as he was sub contracting the job to someone else). Glad we cancelled him and hired another builder in his place. I have evidence of all communication I had with him, incase anyone wants it. I would avoid him at all cost.

Bathroom Fitting- 14 Nov 2019
We had our bathroom completely refurbished and Graham the owner was lovely. He came to give us the quote, visited whilst work was being undertaken to make sure everything was okay and came to make sure everything was finished to how we wanted it. The work carried out was of a high standard and whilst the bathroom work was being completed we also ended up getting our kitchen worktops done by Graham’s team. Chris was the one who carried out our work, he was very friendly and checked we were happy with the work he’d done before he left everyday. I would use Graham again for other work needed around the house.

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.
