Gloucester Walk runs between Hornton Street and Kensington Church Street.
On the south side (at the western end) the houses are mainly three or four-storey stucco houses.
On the north side there is a 1960s style three-storey block of flats and also an imposing red-brick Edwardian terrace of flats.
Gloucester Walk was part of the Pitt Estate.
William Eales, a timber merchant, and Jeremiah Little, a builder, both from St Marylebone had the building lease to develop most of the Pitt Estate, granted by Steven Pitt in 1844. (The terms are dealt with in the history of the Pitt Estate.)
They sub-contracted the work to John Salmon of Wiple Place, Kensington Church Street. He built Nos. 1-12 and 13 Gloucester Walk. Nos. 5-8 were rebuilt by Egglesden and Myers of Paddington in 1871. Originally the street was called Gloucester Terrace.
