Latest review:
We required two extensions - to the rear and above the garage at the side. We contacted Darek as he was recommended to us by a work colleague who lives in our area. We found Darek's prices to be competitive and he was very reasonable to work with, being flexible when our plans changed slightly. Having building work undertaken is never a pleasure, in our view However, we're pleased with the completed work and we found that working with Darek was as stress-free as it could have been. We would (and have) recommended him to friends.

Extensions- 13 May 2026
Agim completed a ground floor extension for me in 2025 and I would not hesitate to recommend him for similar work. The quality of the work was excellent and the team worked tirelessly for months to ensure it was completed on time and for a reasonable price. Agim was able to adapt quickly when any unforeseen problems occurred, always clearly communicating possible solutions to help keep the project moving. Having people in your home can be difficult but Agim is very respectful and considerate, making sure to put our needs first. The results are fantastic and Agim continues to help snag any minor issues that come up. I couldn’t be happier with how things went, testament to his professionalism. Thanks Agim for all your help on this project.
