Single Storey Extension Phase1
Felt compelled to write a review partway through works, as I’ve had such a positive experience upto now. The shell went up in exactly a month since Jass and his team started. There is clearly a lot of project management behind the scenes for this to have happened, and Jass is the man making this happen ! Years of experience mean that Jass has a team that work quickly diligently without sacrificing the quality of workmanship. He listens to our informational requests, and explains what is required from our side to keep making steadfast progress. Have every faith that this will continue in fitoutVerified reviewerJob location: SL210 Extensions / Conversions

Extension, kitchen, bathroom, chimney removal
Excellent service from start to finish. The builder was professional, reliable, and communicated clearly throughout the project. The work was completed to a high standard, on time, and the area was left clean and tidy each day. I would not hesitate to recommend this company and would happily use them again for future work.Job location: TW3RYin P10 Refurbishments
