Wraparound extensions to Holland Park houses — combining a rear and side-return extension into one L-shaped ground floor, designed for conservation consent with structure and build in-house.

A wraparound extension combines a rear extension with a side-return infill, wrapping the new space around the back of the house in an L. It is the most generous single-storey extension a Holland Park terrace can take — adding both width and depth to create a large, open garden-level room in one project.
Because it covers more of the plot, a wraparound has a bigger impact on neighbours and on the rear elevation, so the conservation-area planning case has to be made carefully. RBKC will weigh daylight, outlook, the proportion of garden lost and how the extension sits against the original house.
We design the wraparound to be both ambitious and consentable, engineer the structure across the larger opening, manage the party wall on two boundaries, and build it through to a finished room — one contract, one accountable team.
A wraparound is the biggest single-storey footprint — so neighbours and garden coverage weigh heavily.
Combining rear and side return gives a large L-shaped room in one project.
Covering more of the plot, a wraparound needs a careful conservation-area design and justification.
With work on the rear and the side, the Party Wall etc. Act 1996 usually applies on both.
RBKC weighs how much garden is lost; the design keeps a sensible balance.
