Rear
Extensions

The most popular home improvement in the UK — extend out into the garden and gain the living space your family deserves.

Overview

Your Garden Stays,
Your Space Grows

A rear extension is the most common and most impactful way to add living space to a property. By pushing the rear wall outward into the garden — typically by 3–6 metres — we create the additional kitchen, dining, or lounge space that modern family life demands.

We design each rear extension to work in harmony with the existing property: matching brickwork where required, introducing contrast where desired, and always prioritising natural light through carefully positioned glazing, bi-fold doors, and roof lights. The finish is seamless — inside and out.

Key Benefits

Permitted Development

Single-storey rear extensions of up to 4m (detached) or 3m (semi/terrace) can often be built under permitted development — no planning permission needed.

Open-Plan Living

Rear extensions are the number-one way to create the bright, open kitchen-diner-lounge that tops every homebuyer's wishlist.

Proven Value Uplift

A rear extension reliably adds 10–15% to property value, making it one of the highest-return investments a homeowner can make.
