Extensions- 11 Oct 2023
We recently completed an extension at the rear of our property, along with a kitchen renovation and refurbishment of our reception hall. Abdallah and Hesham were instrumental in this project, providing us with a comprehensive work plan. Their labor costs were exceptionally reasonable, and they demonstrated unwavering dedication to the job. Their hard work was evident throughout the project, not only in the construction but also in coordinating plumbing, electrical work, and kitchen fitting through their skilled team. Abdallah co-ordinated well with building regulations, ensuring that our project complied with all the necessary standards. What truly stood out was their flexibility and willingness to adapt to changes and adjustments, especially when dealing with variations in material sizes. This adaptability greatly facilitated the project's progress and success. Thank you Abdallah and Hesham.

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.

Extensions- 3 Nov 2022
I hired Aras to prepare a Scope of Work document and organise three builders to visit and quote for the works (a side-return extension, and other internal refurbishment). I've been very happy with the work Aras has done. The SoW document was very detailed allowing the three builders to provide like-for-like quotes. He recommended three builders he's worked with before, and provided honest feedback and the pros and cons of each. Lastly, he's always been helpful in answering general design/structural questions I've had. I would definitely hire Aras again and highly recommend him.

Loft Conversion- 29 Apr 2023
My house was totally renovated by this company. I was very satisfied with much of the work. I was informed that I would be given the buildings certificate and the electrical certificate for works completed once final payment was received. I was given the buildings certificate. I was not given the electrical certificate, although the house had been fully rewired as part of the work. I chased up for the certificate but my requests were ignored. I was aware an electrician had come to inspect the works, and the builder who had been on site indicated it appeared to go well. I have now just recently had the electricity in the house inspected by an electrician and have found there were issues that required rectifying.

Restoration & Refurbishment- 3 Jun 2021
Enrico pulled in a great team to refurbish my bathroom. It wasn't a straighforward suite swap out as I added a window, switched from an electric to plumbed shower, properly plumbed in the sink and changed the orientation of the shower and bath. Enrico took all of the stress out of ordering and receiving all the different elements, he added in some great suggestions of final touches and kept close to all aspects of the project until I was fully satisfied with clear timings and payment plan etc. on top. It's an old house and there were curve balls from time to time but Enrico and the team took them in their stride and made it a great experience. I'm totally thrilled with the end result.
