What Is a Wraparound Extension?
A wraparound extension combines a rear extension with a side return extension to create an L-shaped addition that maximises the ground floor footprint of your home. By extending both backwards and along the side of the property, a wraparound extension creates the largest possible ground floor living space from a single-storey scheme.
Wraparound extensions are ideal for terraced and semi-detached houses in London where both a rear garden and a side return passage are available. The result is typically a generous open-plan kitchen, dining and living area that spans the full width and depth of the new ground floor footprint.
LCCL Construction designs and builds wraparound extensions across London and Hertfordshire from our base in Finchley, London N3. Our design and build approach means one company handles everything — architecture, planning, structural engineering, construction and finishing.

Frequently Asked Questions
How much does a wraparound extension cost in London?
Wraparound extension costs in London typically range from £60,000 to £100,000 including full design and build depending on size, location, structure and finishing. A standard wraparound on a Victorian terraced house combining a 3-metre rear extension with a full-length side return typically costs £60,000 to £75,000.
Do I need planning permission for a wraparound extension?
Wraparound extensions often require planning permission because the side return element may not fall entirely within permitted development. Each case is assessed individually. LCCL Construction handles all planning applications as part of our design and build service.
How much space does a wraparound extension add?
A wraparound extension typically adds 20 to 40 square metres of ground floor living space, depending on the size of the rear projection and the length of the side return. This is enough for a generous open-plan kitchen-diner with room for a utility area or additional storage.
Is a wraparound extension better than a rear extension?
A wraparound extension creates more space than a rear extension alone because it extends both backwards and along the side. If your property has a side return, a wraparound is usually the best option to maximise ground floor living space. If there is no side return, a rear extension is the right choice.
How long does a wraparound extension take to build?
A wraparound extension typically takes 12 to 18 weeks to build. The full project timeline including design and approvals is usually 5 to 7 months from initial consultation to completion.
