Florin extended and completely refurbished our 4-bedroom semi-detached house. This included extensive steelwork, underfloor heating, complete re-plumbing and rewiring, excavation, and an entirely new slate roof as well as varying extensions up to three floors high. I cannot say enough good things about his workmanship, professionalism and reliability. His workmanship makes a perfectionist like myself happy. He is also completely professional: even with our difficult neighbours he was always courteous and understanding, and even helped them sort out issues at a moment’s notice that had nothing to do with his building work on our property. And he is also thoroughly reliable. I cannot think of any instance where he committed to something and did not deliver — he even managed to finish all the work on our house ahead of schedule and on budget. We have been so happy with his work that we contracted him to build us a summer house as well, from scratch, and to complete revamping our front garden including elements of hard landscaping. Again he delivered flawlessly and we are very happy with the result. We also continually receive positive comments from people passing by and just seeing the front garden. We have used several other builders in the past on other properties, including far more expensive ones, and none compare to his level of competence, attention to detail in his workmanship, his complete professionalism and thorough reliability. Now that we have found Florin, we will never look for another builder again. I just hope once others experience what he delivers for themselves he will still have some availability for us in the future!

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.

Electrical- 26 Jul 2026
Genuinely one of the worst builders we have come across. David rewired the flat and Stefan plastered the hallway. David is NOT qualified as an electrician and cut corners wherever he could. David leveraged us for money mid job and in the end left the job without finishing and without providing a certificate. David ran cables behind door frames (awful idea), got the cheapest material, forgot where holes were for spotlights and switches among many issues which meant we had to constantly ask our builders to fill the holes and make good. Stefan did the hallway plastering without putting on mesh. The plaster cracked within 2 weeks and the paint keeps cracking and will be a constant problem. When asked to come back and fix the issue - he point blank refused. They were the cheapest quote but we really hope we had gone to someone else

Bathroom Fitting- 2 May 2024
I have employed DL Construction to install a new kitchen and bathroom. They are still working in my house but so far their attitude towards their task and helpfulness have been exceptional. I can not comment about the final product yet but I am sure everything would be finished to a high standard. Nothing seems to be a problem for Javi. He always says 'yes please' and I think that is his middle name. I couldn't have asked for better. Well done (so far) Javi and everyone in DL Construction.

What qualifications and experience do you have as an extension builder in Covent Garden?

An extension builder in Covent Garden should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your Covent Garden extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Covent Garden?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Covent Garden extension builder’s ability to deliver a result that meets your expectations.
