What happens in between is where a build is really won: continuous coordination, repeated checks, and every detail kept in line with the design.

Much of it happens quietly. But every junction, finish, adjustment and decision shapes the space you finally walk into.

A brief for an extension. A home reimagined around the way a family lives.

What began as a plan for a side extension, office, garage and pool evolved into a three-year transformation of this 200m² Coombe home into a 600m² bespoke residence.

Designed around family, entertaining and wellbeing, the home now features a private wellness suite, cinema, sunken lounge, hidden kitchen and 13m reflective pool.

Simple Sketch to Ex*****on -THE BOSINNEY STORY

From stage zero, our principal designer Youno worked closely with Naz and Alicia to understand how they live, work, entertain and unwind.

Every space, detail and decision was shaped around their everyday needs, creating a home that feels considered, connected and completely personal.

This is more than a completed project. It is a home built for living.

FROM ELEVATION TO REALITY.

Every successful interior begins with a clear design process.

For this bespoke staircase, we developed four distinctive design options, exploring materials, finishes, lighting and architectural details. Each concept was carefully refined around the client’s vision and the character of the space.

A serene place to come home to.
Everything feels balanced, open, at ease.

Air moves freely,
and morning tea on the patio—
something you quietly look forward to.

If you’re planning an extension in London, pause!

Start by defining what matters, understanding what’s possible, and avoiding early builder conversations without a clear scope.

Note: A structured start makes all the difference.
