Basement construction in Fulham

Full basement construction under a Fulham home — excavation, underpinning, reinforced concrete structure and waterproofing, taken through to a space ready for fit-out.

The project

Classic basement construction in Fulham: a new basement level under an existing west London house where the only way to add space was down. The property remained supported throughout by a sequenced underpinning scheme.

What we did

  • Breaking out the existing ground floor slab and sequenced dig
  • Mass concrete underpinning to the engineer’s design
  • Reinforced concrete slab and retaining structure
  • New drainage with sump and pump chamber
  • Cavity drain membrane waterproofing ready for fit-out

The result

A dry, structurally certified new level under the house, handed over ready for insulation, services and finishes.
