Fulham · South West London
Fulham is side return country. Rows of Victorian terraces with narrow alleys running alongside the kitchen, and gardens that reward a well-designed rear addition. We design and build extensions, loft conversions and basements across SW6, under a single contract.

Working in Fulham
Fulham's housing stock is dominated by late Victorian terraces built between the 1880s and 1900s. Most have a two storey rear projection with a narrow side passage alongside it, which is why side return extensions and wraparound extensions are the most common projects we take on here. Filling that alley typically adds a metre or more of width across the full depth of the ground floor.
Loft conversions are equally common. The butterfly and closet-wing roof forms found across SW6 usually suit a rear dormer, and on terraces where headroom is tight a mansard is often the only way to get a usable full-height room.
We handle design, planning and construction as one team. That matters in Fulham, where party wall agreements are almost always in play and the build sequence needs coordinating with neighbours on both sides.
Services in Fulham
Fulham sits in the London Borough of Hammersmith and Fulham. Much of SW6 falls within a conservation area, so a good proportion of our work here goes through a full planning application rather than Permitted Development.
Our design-and-build model means the drawings and the build come from the same team, so what gets approved is what gets built.
Planning in Fulham
Hammersmith and Fulham has extensive conservation area coverage across SW6, including Hurlingham, Parsons Green, Walham Green, Moore Park, Sands End, the Peterborough Estate and Munster Village. Properties inside these areas have restricted Permitted Development rights, and most extensions need a full planning application.
Outside the conservation areas, standard Permitted Development rules apply and many rear extensions and rear dormers can proceed without a planning application, subject to the usual size and design limits.
Basement projects in Fulham need a full planning application and a structural method statement. We check the planning position for every property before any design work starts.

Property Types
Fulham is overwhelmingly late Victorian terraced housing, much of it built speculatively in the 1880s and 1890s. The typical plan is two rooms deep with a rear closet wing, a side passage and a modest garden. These houses respond very well to side return and wraparound extensions.
The Peterborough Estate is known for its distinctive red brick houses with lion statues on the gables. Sands End has a mix of former industrial buildings converted to residential alongside newer riverside development. Parsons Green and Hurlingham have larger detached and semi-detached properties on wider plots.
