Loft conversions and extensions are what we do best — dormers, L-shapes, side returns and more... delivered in 8–10 weeks by the same tight-knit team every time.

No subcontractor roulette, no disappearing builders.

We also take on full top-to-bottom refurbishments across North London, handling everything in-house from structural calcs to the final coat of paint.

Based in Finsbury Park, on the tools since 1991.

Free quote within 24 hours — and we actually turn up to give it.
