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.

Extensions- 10 May 2020
Dave and his team built a side extension over our existing garage and converted our garage into a TV room. The project went well with no real issues and was very efficient. The build and finish was done to high standard and the site was kept tidy. Dave would question the designs if he thought something could be done better. I would definitely recommend Dave for any building projects.

Extensions- 30 Aug 2024
We recently used Build on Time Ltd to build a ground floor extension and remove chimney breasts from 4 rooms on a home renovation project. Paul and his team delivered within budget and ahead of time. This did not compromise their attention to detail or care taken with their work. All were extremely hard working and committed to getting as much out of each day as possible. They were reliable, trustworthy and a pleasure to be around. We would definitely recommend!

Ryann and his team first completed a multiple room ground floor extension for us, including the installation of a new kitchen and bathroom. We were so pleased with the work that we asked him to build an outdoor garden room from scratch and completely refurbish our other bathrooms. We have always found Ryann to be friendly, punctual, knowledgeable and honest and I am more than happy to give my recommendation.
