I wanted a side infill extension, converting a one bed into a 2 bed. The works was undertaken by Coulsdon Builders which took around 8 months. I made several changes throughout the project hence the delay. They were so accommodating and never had an issue and was always happy to cooperate. The cost of build was £120k and we stuck to the budget. I am delighted with the works and am grateful they made my house a home. They were clean and tidy on a building site and always kept me updated on progress. This is one builder that I highly recommend and trust. Great work guys and thank you again!

Kitchen Fitting- 30 Oct 2026
It didn’t give me an option to give no stars. From the 13/10/26 we agreed a price and a date. On the morning of the agreed date he calls to cancel and tell me he can’t do the job. Maybe too small of a job I don’t know but it has extremely inconvenienced me and reduced me to tears. 2 weeks have gone by only for him to cancel…I WOULD NOT TRUST THIS BUILDER I’m extremely disappointed, he seemed like a pleasant professional man yet I got the complete opposite service. I’m not sure if my race or gender has anything to do with it but that’s how the situation has left me feeling.

Extensions- 18 Dec 2019
What a wonderful extension Dan has built for my family and I! Everyone who visits us comments on how lovely it looks - we are extremely happy! From the moment I spoke/met with Dan I knew he would be the builder I would assign for this project. He was friendly, knowledgeable and spent time explaining the work which he would conduct. Dan and his team were always on time and worked hard all day. As promised, Dan completed the job on time and to budget. As with any build, we did encounter some issues, although Dan resolved these without any problems. I would 100% recommend Dan and his team! Give them a try, you'll be pleasantly surprised! Thank you Dan and co.
