Custom Joinery & Bespoke Timber Work
It's surprisingly hard to find a dependable joiner who turns up when they say they will and treats your property with the respect it deserves. We spend our days designing, measuring, and building proper solid timber pieces for London homes. We simply refuse to deal with flimsy flat-pack boards.
London houses throw up all sorts of weird angles and awkward spaces. One job might involve copying Victorian skirting boards millimetre for millimetre. The next week — building a timber garden office. Nothing really surprises us. We just look at your space and figure out how to build something that lasts.
Conservation Area Expertise: We do a lot of work in conservation areas. Matching old profiles to keep the council happy is second nature to us — from heritage windows and doors to period-accurate joinery details.

Timescales depend on the scope. A single built-in wardrobe typically takes 2–3 days on site. Larger projects like staircases or full room fit-outs are built off-site over 2–4 weeks then installed within a day or two.
