South Kensington is mostly stucco flats, with mews behind. We extend garden flats, mews houses and the odd whole house.

Room to add in a flat or a mews.

NU Projects is a design and build company in Fulham SW6, founded in 2010. We handle house and kitchen extensions in South Kensington SW7, under one contract. A rear kitchen extension typically runs £160k to £250k. A side return extension typically runs £140k to £220k. Call 020 7731 6841, and a budget estimate typically follows within seven days.

South Kensington is tall stucco terraces of four or five storeys. Most were split into flats long ago.

So the classic brief here is a garden flat at lower ground level. Its kitchen pushes out onto its own patch of garden.

Behind the terraces run the mews. A mews house has little garden, so any gain goes up or inside.

The borough resists an extra storey where a mews roofline is still unbroken. Where roofs already vary, infilling a gap can be allowed.

We read the lease, roofline and neighbours’ rear line before drawing.

What the borough allows for South Kensington flats and mews.

Garden level: Policy CD13 holds a rear addition to the line set by neighbouring extensions.
Mews roofs: Extra storeys are resisted where the roofline is unimpaired by extensions.
Infill: Where a row already has varied roof extensions, infilling can be permitted.
Merging flats: Policy HO1 does not allow existing self-contained homes to be merged into one.
Flats: Flats have no householder permitted development rights. Outside changes need planning.
