Architecture for London is currently designing several residential projects in Hammersmith and Fulham

At Caithness Road in Brook Green we are extending and renovating a Victorian house. A fully glazed upper ground floor extension brings an abundance of natural light into the new space. A section of the upper ground floor plate is removed to create a large double height area in the kitchen extension below. Floor to ceiling oak sliding doors form flexible partitions that allow the reception rooms to be either used as an open plan space or divided for privacy.

Our architects work in all areas of the borough, including Ravenscourt Park and Brook Green W6, Parsons Green, Fulham and West Brompton SW6, West Kensington W14 and Shepherd’s Bush W12.


In Hammersmith and Fulham’s SPD, Housing Policies 6, 7 and 8 contain helpful guidance on residential projects including rear extensions. Some key items to note are:

  • The council will consider rear extension applications in the context of the existing established rear building lines in a terrace.
  • Rear extensions must be no longer than 3.5 metres from the original rear wall of the house.
  • Side return extensions may not extend above a height of two metres at the boundary with the adjacent house.
  • Planning permission will not be granted for roof terraces or balconies if their use is likely to cause a nuisance to existing neighbours.

It is worth noting that, in some cases, homes can be extended to greater dimensions under permitted development rights. Basements are covered in the SPD Housing Policy 9, and key considerations are as follows:

  • A Subterranean Construction Method Statement must be submitted with the planning application, and this should be produced by an appropriately qualified structural engineer.
  • Any basement development must not increase the risk of flooding, and should also meet existing guidance in relation to light wells.
