Wrap around extensions

At Bloom Builders, we design and construct bespoke wrap around extensions across London, with a strong focus on Victorian and Edwardian homes across South West London. Wrap around extensions combine rear and side return extensions to create significantly larger ground floor living spaces with improved natural light and stronger connections to the garden.

We deliver both full design and build packages and construction only services, depending on project stage and client requirements.

What Is a Wrap Around Extension?

A wrap around extension combines a side return extension with a rear extension to form an L shaped addition around the original rear structure. This approach is particularly suited to Victorian and Edwardian terraced properties where ground floor layouts can be restrictive.

Wrap around extensions allow major layout improvements while retaining usable garden space.

Benefits of a Wrap Around Extension

Natural Light
Allows large glazed doors, rooflights and full height glazing to be incorporated.

Layout Flexibility
Supports open plan living, zoning and multi functional spaces.

Property Value
High quality extensions can significantly improve long term property value and buyer appeal.
