Professional Building Services in Wrap-Around Extensions

For over 22 years, Foundation and Finishing has been delivering exceptional Wrap-Around Extensions services across Greater London. Whether you're adding space with a side return, creating an open-plan kitchen-diner, or building a double-storey addition, we handle every detail from planning permission to final completion.

Wrap-around extensions combine a side return and rear extension to form an L-shaped addition that can dramatically enlarge the footprint of your home. This configuration is especially popular in terraced and semi-detached properties where you want both a larger kitchen and additional living or dining space. By extending in two directions, we can replan the entire ground floor to improve circulation, storage, and natural light.

These projects typically require full planning permission due to their size and impact, and we manage the entire planning process on your behalf. Our designs carefully consider neighbouring properties, garden outlook, and structural requirements, often involving substantial steelwork to open up existing rooms. The finished result can accommodate generous kitchen layouts, islands, informal seating, and wide openings to the garden, creating a true multi-functional family hub.
