Under Earl's Court streets the diggable stock is narrower than the postcode suggests: Victorian terraces and mansion blocks on a borough-boundary fringe. We filter out leasehold flats first, then test whether a freehold house truly needs below-ground space rather than a rear or loft enlargement toward South Kensington.
The planning frame for Earl's Court is Kensington & Chelsea / Hammersmith & Fulham: RBKC or H&F authority must be fixed per address. We scope evidence to that authority’s lists and refuse generic “London basement policy” numbers that do not apply to this pin.
Title is the first Earl's Court drawing. If the client is a lessee under a freeholder who retains structure and subsoil, we stop the basement brief and redirect to works they can actually consent. Only clear freehold control proceeds to investigation.
We commission plot-specific ground investigation for Earl's Court basements: foundation depths, groundwater and obstructions decide the retaining method and whether under-garden elements survive, long before application drawings are fixed.
Because converted houses and short gardens, Earl's Court basements notify early and often. We map every notifiable owner before a programme date is offered, including internal parties in converted houses.
For Earl's Court basements, we treat water as a primary design driver: dual-system waterproofing to BS 8102, twin pumps, backflow protection and ventilation planned with the tanking so the box does not become a sealed cellar.
On Earl's Court plots the lightwell package — retaining walls, guarding, steps, grilles — is designed first. Short gardens toward West Brompton and tree constraints can veto a habitable dig even when the structure is sound.
Earl's Court clients often arrive asking for a basement when side-return and loft routes remain common first steps. We price both routes so the dig is a choice, not a default.
Distinctive to Earl's Court: Victorian terraces and mansion blocks on a borough-boundary fringe combined with converted houses and short gardens. That pairing changes bay sequences, spoil routing and which households must be served notices before excavation.
How RBKC or H&F authority must be fixed per address meets the site compound in Earl's Court: if the lightwell eats a short garden or trees block the only access, the floor plate shrinks until external works are buildable toward South Kensington.
Do not copy a dig from South Kensington or West Brompton into Earl's Court by postcode similarity — Kensington & Chelsea / Hammersmith & Fulham evidence thresholds and local grain differ street by street.
Construction hours and vehicle routing on Earl's Court streets are written into the package early, because neighbour awards and Kensington & Chelsea / Hammersmith & Fulham construction-management expectations often gate the start on site more than the decision notice does.
Delivery in Earl's Court runs investigation and structure before Kensington & Chelsea / Hammersmith & Fulham submission, then awards and building regulations; we set that longer programme at the first meeting so the dig is planned as a project, not an add-on. Spoil logistics and temporary works are written into the package rather than discovered at tender.
