House Extensions
East London
Rear extensions, side returns and double-storey additions across East London. One team, fixed price, our own supply chain.
Which Extension
Is Right for You?
East London homes vary enormously — Victorian terraces, 1930s semis, post-war semis, detached. We've built extensions on all of them.
Unlike most builders, we build the structure and fit out the inside — including the kitchen if you want it — all through our own supply chain.
Every Type of Extension
Rear Extension
The most popular type. Extends your kitchen and creates open-plan living with doors onto the garden.
Side Return
Fills the narrow side passage common in Victorian terraces. Transforms a cramped kitchen into full-width space.
Double-Storey
Add space on two floors at once — kitchen below, bedroom above. Best value per m².
Wraparound
Combines rear and side return into one large L-shape. Maximum kitchen-diner space.
Over-Structure
Build above an existing garage or single-storey section to add a bedroom or office.
Garden Room
A detached garden studio or office, fully insulated and powered.
