Wrap-Around Extensions in Barnet & North London.
Combine a rear extension and side return into one transformative project — creating the open-plan home you've always wanted.
What is a wrap-around extension?
A wrap-around extension combines a single-storey rear extension with a side return extension, creating a large L-shaped addition that wraps around the corner of the property. The result is one of the most dramatic ground floor transformations available — significantly widening and extending the footprint of the home to create a spacious, open-plan kitchen, dining and living area that flows seamlessly to the garden. Wrap-around extensions are one of our most popular projects across Barnet, Finchley, St Albans and the wider North London and Hertfordshire area. They work particularly well on Victorian and Edwardian terraced and semi-detached houses.
Is a wrap-around extension better value than two separate projects?
Yes — in most cases, combining a rear extension and side return in a single wrap-around project is more cost-effective than doing them separately. Preliminary costs, scaffolding, structural engineering and project management are shared across the whole project. You also have the benefit of a single period of disruption rather than two. Our team will advise on the best approach for your property and budget.
Common questions
Do I need planning permission for a wrap-around extension?
This depends on the size and location of your property. Many wrap-around extensions fall under Permitted Development, but larger wrap-arounds or those on conservation area properties will require planning permission. We assess this for every client.
How much does a wrap-around extension cost in North London?
A typical wrap-around extension in Barnet and North London costs between £60,000 and £100,000 depending on size and specification.
Can I have bi-fold doors on a wrap-around extension?
Absolutely — bi-fold or sliding doors across the rear and/or side of the extension are one of the most popular features, creating a seamless connection between your open-plan interior and the garden.
