Extensions- 4 Nov 2023
Overall me and my husband are very satisfied with the workmanship and with the final result of our my fake cladded garage door with the new aluminium framed window. The original garage was converted into a habitable room 7 years ago with only a rooflight to bring light into the room, which is now my husband's office and this new window will make a lot of difference therefore we are very happy with the finished work. The work was done very quickly, the builders turned up on time and they were very efficient and helpful, they took particular care when installing the composite slatted panels to the marine plywood. The main contractor Pawel Speiwak also came on site to inspect the works during construction. The quote was also very competetive, a good value for money. I would definetely use them again for any future work in my house and recommend them to other people.

Conversions - General- 4 Jan 2026
Pat was a pleasure to deal with from beginning to end he had everything covered and made the whole project a seamless experience. He provided me with a professional quote and had the patience to deal with my questions. He started the project on time svd no thing was too much trouble, when I needed a roofer to fix some issues with a leak he had someone on the job within a day. He handled every aspect of my garage conversion effortlessly and had the job finished on time right before Xmas. Would 100% use Pat again. Great guy who also knows good trades people. Thanks Pat.

Extension Builder in Stevenage
I have spent 40 years in the construction industry, starting straight from school where I completed a five-year apprenticeship in the glass and glazing industry. Over the years, I progressed through all areas of the window and fenestration sector, gaining extensive hands-on experience in all types of glazing, window systems, fire doors, conservatories, and associated installation works. As my career developed, I broadened my expertise further by moving into carpentry and developing practical skills in a range of additional trades, including brickwork, tiling, kitchen fitting, and general building works, to name a few. This diverse background allows me to offer a well-rounded understanding of both specialist and general construction projects. We operate throughout Bedfordshire, Hertfordshire, Northamptonshire, and Oxfordshire, including all surrounding areas.

Extensions- 10 Mar 2025
Hired paul to carry out works to open up my rear wall and install a new RSJ steel beam for a bifold door. From day one paul helped me out with some issues i was having with my structural engineer design, priced up the works which was very competitive with other builders and While having a visit before works started, i asked paul if he could do some extra works (installation of plasterboard walls and plastering) which he was happy to do. Todd then started works within a few days. Now all the works are finished and im very happy with the finished product. Paul and Todd were brilliant and would happily recommend them to people if they need any works done. I will be using them again in the future.
