Battersea digs belong on freehold houses, not riverside mansion flats. Victorian terraces with closet wings and short rear gardens dominate the workable stock; mansion blocks and converted houses usually fail ownership. We filter title and building type before any cinema-room brief is taken seriously.
Wandsworth decides Battersea basements as full householder applications with engineering evidence. Tight terrace grain near the park and river means external lightwells are development, not PD. Other boroughs’ basement rules are not treated as Wandsworth policy for SW11.
Freehold control is mandatory. Ground-floor flats in converted terraces rarely own subsoil. We stop those enquiries at title and redirect to works the lease can support.
We commission plot-specific ground investigation for Battersea basements: foundation depths, groundwater and obstructions decide the retaining method and whether under-garden elements survive, long before application drawings are fixed.
Mid-terrace Battersea basements often mean two party wall awards at once. Sequenced underpinning, monitoring and notices are the critical path. Spoil usually leaves through the front door and a thin passage — rear access is not assumed.
For Battersea 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.
Short Battersea gardens spend amenity fast on any lightwell. Neighbour daylight on dual flanks is tested in section. We design the external package first and cut the buried plate to match what remains of the garden.
Side-return infills and loft conversions remain the first-value moves on many Battersea terraces. We price them against a dig so excavation is chosen only when above-ground options are exhausted.
Park-edge SW11 streets and denser inland terraces do not share the same compound story. Parking stress and one-way patterns reshape lorry plans; we write construction management to the street, not to a single Battersea label.
Riverside mansion stock is almost never a basement project for an individual lessee. We say that early rather than after fees are spent.
Compared with Balham’s slightly deeper plots, Battersea mid-terraces more often hit dual awards and shorter gardens. Those two facts dominate programme more than engineering fashion.
Wandsworth evidence is confirmed for the address; a statement written for Fulham or Westminster is not recycled into SW11.
Where a side return already occupies the rear wing, drainage and remaining garden depth are re-surveyed before a basement is treated as a simple next phase — the foul run under the return is often the real constraint.
A Battersea dig package sequences title, dual party wall mapping, lightwell amenity on a short plot, and Wandsworth evidence before any under-garden cinema brief is priced as if the garden were still empty.
Delivery in Battersea runs investigation and structure before Wandsworth 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.
