Double Extension

Double Storey Extensions in Slough & Berkshire

Double the Space. Double the Value. One Expert Build.

A double extension — extending both ground floor and first floor simultaneously — is one of the most transformative and cost-effective ways to grow your home. Rather than just adding space on one level, a double extension creates significant living space across two floors, dramatically increasing both your quality of life and your property’s market value. At Charda Punjab Ltd, we manage double extension projects from the initial planning stage through to the final finishing touches — delivering outstanding results that feel like a natural part of your home.

Why a Double Extension Makes Financial Sense

A well-designed double extension typically adds between 20% and 30% to a property’s market value — often far exceeding the cost of the build itself. It is almost always more cost-effective per square metre than a single-storey extension, as the groundworks, scaffolding, and roof costs are shared across both levels.
