A wrap-around extension combines a rear extension and a side extension into one L-shaped build. It's one of the most effective ways to maximise ground floor space — creating a large, open-plan living area that completely transforms how you use your home.
How Much Does a Wrap-Around Extension Cost?
Prices include VAT and are based on standard specification. Actual costs depend on site conditions and finishes.
Do I Need Planning Permission?
Wrap-around extensions usually require full planning permission because they extend in two directions. The side element often doesn't fall within Permitted Development limits, particularly if it's more than half the width of the original house.
The planning application process typically takes 8–10 weeks. We handle the entire process as part of our Design & Build service.
What Can You Fit in a Wrap-Around?
Open-plan kitchen-diner
The most popular layout — a large kitchen with island, dining area, and living space
Separate utility room
Tuck the washing machine and laundry out of sight in a dedicated utility
Downstairs WC
Add a ground floor toilet without sacrificing living space
Playroom or snug
A separate, quieter space for children or a cosy TV room
Home office
A dedicated workspace with its own entrance if needed
Bifolding doors to garden
Wide openings that connect your new living space to the outdoors
How Long Does It Take?
A typical wrap-around extension takes 14–20 weeks to build, depending on size and complexity. Add 8–10 weeks for planning permission if required, and 2–4 weeks for design and structural drawings.
Is It Worth It?
Absolutely. A wrap-around extension can add 15–25% to your property value in Essex — often more than the cost of building it. More importantly, it gives you the space you need to live comfortably without the cost and stress of moving house.
