Workers in Building Site

Wraparound Extension – Sarah L.

(Wimbledon, London)​​​

​

​

We had a wraparound extension done on our Victorian semi, and we couldn’t be happier with the result. From planning permission to final finishes, everything was handled professionally and on time. The team was tidy, polite, and always communicative. Our kitchen and dining space are now bright, open, and exactly what we imagined. Highly recommend for anyone considering a home extension.

HMO Conversion – James K. (Croydon)

​​​

​

​

I hired a team for a full HMO conversion of a 5-bedroom house, and they delivered beyond expectations. They handled the project end-to-end — fire regulations, soundproofing, en-suites, and even the planning with the council. What impressed me most was their understanding of compliance and investment returns. The work was high quality and completed within budget. As a landlord, finding a reliable team like this is gold.

Basement, Loft & Rear Extension – Priya D. (Dulwich Village, South London)

​

We undertook a major renovation — basement dig, loft conversion, rear extension, and a full-house refurb. A huge project! The project manager kept everything on track and transparent. We lived off-site during the work, but they sent regular updates and even helped with finishes selection. The craftsmanship is excellent, and the house feels brand new but still full of character. We’ve had so many compliments.
