Onslow Gardens

The archetypal South Kensington address: long terraces of white stucco facing a private communal garden, mostly converted into flats of real proportion. Raised-ground floors here have the ceiling heights and window scale that define SW7. Garden rights are attached to particular flats rather than to the street, so check the paperwork before you fall in love.

Across 10 registered transactions, Onslow Gardens sits at a median of £2.05m — a useful anchor for anyone valuing here. The spread is wide — £1.05m to £5m — which is normal on a street where condition and floor level do more to the price than the postcode does. Stock leans towards flats (90% of sales), with 10 leasehold titles among the latest 10. The most recent registered sale went through on 6 Mar 2026.
