London Garden House Extension

Rear extension & interior renovation

Overview

A carefully designed rear extension in Richmond that dissolves the line between the house and its private garden. Large-format glazing and a generous rooflight pull daylight deep into the open-plan kitchen and living space, while dark timber, white marble and soft neutral furnishings keep the character refined yet genuinely welcoming — contemporary classic luxury, lived in.

The Brief

Challenge, approach, outcome

01

The challenge

A rear extension on a period London house is judged twice: from the garden, where new brickwork has to sit honestly beside the old, and from inside, where an open plan can easily become one loud room with a kitchen in it. Deep plans also die in the middle — daylight from the garden end rarely reaches the heart of the house.

02

Our approach

The extension was drawn as one calm horizontal volume under the original gables, with full-width sliding glazing that folds the garden into the room. A generous rooflight was cut over the centre so the middle of the plan is the brightest part, not the darkest. Inside, the plan splits by material: a dark timber media wall and joinery carry the living side, a white marble island carries the kitchen, and one continuous floor lets the two halves share the garden. The old front of the house was renovated to match — marble hallway, dark doors and lit stair treads carrying the new language back to the front door.

03

The client’s goal

A house that gains a garden room without losing its street face — brighter in the middle, calmer at the edges, and one language from the front door to the back fence.

Lighting strategy

Architectural first: a cove halo traces the extension ceiling, the rooflight carries the day, pendant drops mark the island, joinery shelves glow from within, and outside the garden is lit tree by tree so the glazing never turns into a black mirror at night.
