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.

Extensions- 3 Sep 2018
Zen has helped transform our home, we’ve drawn a lot of confidence from his considered approach and thorough work ethic. He’s so far addressed the cause of cracks to exterior walls of our property and has provided lasting solutions. We also asked him to plaster our hallway and update the banisters for us, Zen has done a great job of reinforcing the strength of the original features whilst retaining the property’s character. Very good with pets too. Looking forward to the next project.

We recently completed a large renovation which included extending our kitchen at the rear of the property, changing levels in the garden and converting our loft with an additional bedroom and en-suite. Ben, Steve and the rest of their team were amazing throughout. We had difficulty moving out of the property as our short term let fell through but the team worked tirelessly to enable us to ‘live in’ whilst much of the build was going on (which I know wasn’t ideal!) I highly recommend Integrated Homes as Ben and Steve were so knowledgeable, considerate and professional in their work.

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!

KB building and carpentry
Rating: 5 out of 5
Extension Builder in Hertfordshire
Hi I'm 52 years old i cover all aspects of carpentry . With my years of experience of running new build and extensions I've come across lots of issues to over come with myself and other trades. I have good network of trades I've worked with over the years that I can also rely on and trust to deliver a great project. My attention to detail and finishing a job also comes with my length of time In this industry. There isn't a job I wouldn't consider being it a secret door into a gym. Which I have not long finished. To building a house from the footing to finish. O will help design a project and also follow a drawing and deliver as expected. I have a full range of photos and also a list of happy clients that I can introduce you to.

Mr Williamson did a fantastic job installing and repairing fire doors in my HMO property to the exact standard required by the council. He was very professional, punctual, and highly attentive to detail throughout the entire project. The quality of his work was exceptional, and he ensured the job was completed within the agreed deadline. I’m very pleased with his service and would gladly recommend him to anyone looking for a reliable and skilled carpenter.
