About Nathan

15 years on site. Hundreds of extensions. One honest guide.

I've spent my career building the extensions that change people's homes — and watching the same brilliant homeowners go through the same unnecessary fear, every single time. Extensions Explained exists to change that.

My background

I've built extensions my whole career. But this is different.

I started in construction straight out of school and never looked back. Over 15 years I've worked on hundreds of extensions and loft conversions across South London — from single-storey kitchen extensions to full rear additions and everything in between.

I know every stage of a build from the inside. I know what groundwork looks like when it's going well and when something's off. I know what a good contract looks like, what a fair payment schedule is, and what questions a homeowner should be asking but never does.

And I know — because I've watched it happen hundreds of times — that the people who struggle most aren't the ones with the hardest projects. They're the ones who were never shown the map.

"After years on site, I realised the gap wasn't in the building. It was in the explaining. Nobody was doing that part — so I built the thing that should have existed all along."

Extensions Explained isn't a consultancy or a company. It's me, Nathan — a builder who's been on your side of the fence too, and knows exactly what it feels like to not know what happens next.

What I've heard at kitchen tables

The things homeowners actually say.

Over 15 years and hundreds of builds, I've heard the same fears, the same questions, the same quiet worries. These aren't made up. These are real.

We were so worried about the whole thing, we almost didn't go ahead with it.

I didn't know what happened first. And that was the most scary bit.

Why this exists

Confidence before construction.

Every homeowner I've ever worked with deserved to understand what was happening to their home. Most of them didn't — not because they weren't smart enough, but because nobody ever explained it to them.

Drawings are drawn for builders. Contracts are written for builders. The whole process assumes you already speak the language. You don't — and you were never supposed to.

The Extension Confidence Session is the thing I wish had existed for every homeowner I've ever built for. One hour. Your drawings. Your questions. Total clarity — before anything begins.
