House extensions in London

A house extension is only as good as the structure under it. We do the whole sequence — foundations, structural steel and beam work, walls and roof, then the fit-out — so nothing gets lost between contractors.

  • Kitchen extensions that open the ground floor to the garden
  • Rear extensions, single and double storey
  • Side return extensions that turn the corridor into a room
  • Foundations, structural work, drainage and roofing
