Rating: 4.5 out of 5
Extension Builder in Oxfordshire
The carpenter you need to get the job you want done, everything from First Fix (Stud, Roof work, etc) to Second Fix (Door, Flooring, Skirting & Architrave, etc). My knowledge and expertise also extends past wood work into plaster, ground, brick work and CAD where depending on how you want a certain job to look aesthetically, we can design it before it’s built to achieve the result you want. Insured, qualified and willing to give the best service possible.

Extensions- 15 Jan 2025
Finlay did work to a high standard and quality. However, he was repeatedly unable to meet agreed timelines and was much slower than other contractors to complete the work. The project also ended up costing much more than originally quoted. We ended up having to terminate our contract and finish the project with other contractors. This was disappointing as Finlay is a lovely guy.

Extensions- 8 Oct 2025
Jason and his team have just completed our wraparound extension, and the result has exceeded all expectations. Their workmanship, accuracy, and attention to detail are outstanding, and the whole process was smooth and stress-free. They stuck to timings, kept the budget in mind, and made everything feel effortless. Partway through the build, Jason had to undergo an operation and was signed off for five weeks. Remarkably, nothing was delayed — his team carried the project seamlessly, and with Jason still on site when he was able to be, everything ran perfectly. It’s a real credit to how capable they all are and the consistently high standards they work to. The only negative thing I can say is that we were sad to see them leave – they’ve been such a positive part of our daily lives over the past eight weeks. The finish is exceptional and we’re absolutely over the moon. We couldn’t recommend Jason and his team highly enough.

When I was looking for quotes, Lukasz was the only builder who provided a fully detailed breakdown. From the start, he was professional and punctual, arriving exactly on time for our first meeting. He offered great recommendations on the best ways to approach the refurbishment and was flexible enough to let me source my own materials. Most importantly, he provides a warranty which he has already honored to fix a minor fault from another professional. It has been a pleasure trusting Lukasz and his team with my full house renovation.
