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.

Ben and Genc did a fantastic job. They fitted the fire and smoke strips into my fire door very neatly and cleaned up thoroughly. They were able to come out quickly and it took them no time at all. I am delighted with the result!

Carpentry- 7 Mar 2021
Great service and value for money. We commissioned Paul to build a garden office. The job was completed in less time than originally expected and the quality of the workmanship was excellent. I have no hesitation in recommending Paul and we have already passed his details on to a neighbour who wants a garden studio built. We will also hopefully be using Paul's services again in the future on a loft conversion.

Conversions - General- 25 May 2022
Pawel worked on my son's property in Notting Hill, London. The final result was absolutely wonderful. I found Pawel incredibly helpful, skilful and willing to change things last minute, as I procrastinated over every job! He left the property clean and tidy each day, and the end result was a flat that has been transformed and improved beyond recognition. I would thoroughly recommend Pawel and will definitely use him again in the future.

They were not focused as working on different jobs at the same time. Window and plumbing was ok, but the painter was not recommendable. They fixed some shelves which fell next day. One of them came back to fix it but it fell again. They didn’t bother to come back .
