Bespoke subterranean rooms in London

A well-planned underground room can create useful space without changing the building’s above-ground footprint. The design should begin with how the room will be used and how it connects to the existing property.

Start with the purpose of the room

Subterranean space can be designed for uses such as a home gym, cinema or media room, wine cellar, workspace, swimming pool or flexible living area. The most suitable option depends on the property, site conditions and the wider project design.

Questions to address before construction

Access, structure, headroom, daylight, ventilation, acoustics, building services, waterproofing and future maintenance all influence the layout. Considering these subjects together helps the project team avoid solving one requirement at the expense of another.

New-build or beneath an existing property

A room planned with a new development can be coordinated with the structure from the outset. A retro-fit basement beneath an existing property also has to respond to the retained building, access constraints and construction sequence.

Design and build with an experienced basement team

With more than 30 years’ specialist basement experience, Basement Structures works with homeowners, architects and developers across London, Greater London and the Home Counties. Our service can take a project from excavation and structural construction through to the finished underground space.
