Wraparound Extensions
Maximum Impact
Combine a side return and rear extension in one project for an L-shaped transformation. The ultimate open-plan living solution for London terraces.
Why Choose a Wraparound Extension?
A wraparound combines a side return and rear extension into one L-shaped project. Instead of building in two phases, you get maximum space in a single build—typically adding 30-50sqm to your ground floor.
The result? A genuinely transformative open-plan space that flows from kitchen to dining to living, with floor-to-ceiling glass connecting to your garden. This is the project that makes guests say "wow" when they walk in.

Why Build a Wraparound?
Better Value
Building both together saves £5-10k in setup costs, scaffolding, and project management versus two separate builds.
Faster Timeline
16 weeks total versus 22+ weeks for two projects. That's 6 fewer weeks of living in a building site.
Single Disruption
One build period, one temporary kitchen, one stretch of mess. Versus two separate rounds of chaos.

Wraparound Extension FAQs
Actually, no—it's typically £5-10k cheaper. Building both together saves on duplicate costs: scaffolding, site setup, project management, and design fees. Plus you avoid having to re-landscape twice.
Often yes, especially if the rear extension exceeds Permitted Development limits (6m for detached, 3m for terraced). But we handle the entire planning process—drawings, consultations, submission, and approval—as part of our service. Planning success rate: 96%.
14-18 weeks for the build itself, plus 6-8 weeks for design and approvals. So roughly 5-6 months total from initial consultation to moving furniture in. That's still 6 weeks faster than two separate projects.
Based on our completed projects across London, wraparounds add £120-180k to property values. With a £60-80k investment, that's 150-225% ROI. Plus you get to live in your dream space rather than moving house.
