Our Story

From a single toolbox to a trusted local name

Roshi Builders started the way most good trades do — one person, one van, and a refusal to leave a job half right. Word spread through neighbours and friends, and over twelve years that turned into a small, dependable team known across London and the Home Counties.

We deliberately stayed small. It means Roshi is still on site, still checking the level, still the person you speak to on the phone. Nothing gets subcontracted out to someone who doesn't care as much as we do.

Today we handle everything from a re-skimmed ceiling to a full loft conversion, and our bespoke media walls have become the projects clients most often recommend us for.

Founder

Roshi

Time-served builder, plasterer and tiler. On site most days, and the person who signs off every project.

“I've never wanted to be the biggest builder in the area. I want to be the one people recommend without hesitating.”

Why Choose Us

Three reasons clients come back

Uncompromising Quality

We use trade-grade materials and proven methods. If a wall isn't flat or a grout line isn't straight, it gets redone — not signed off.

Reliability You Can Plan Around

Agreed start dates, realistic timescales and daily updates. You'll always know who's coming and what's happening next.

Obsessive Attention to Detail

Mitred edges, hidden cabling, flush finishes. The small things nobody notices are exactly the things we spend the longest on.

Our Values
