Fuller information:

By the C17th the land in this area was largely owned by Henry Smith's Charity Estate, with part owned by the Thurloe Estate. Henry Smith, Alderman of London, had died in 1628 and left his fortune in trust for charity. The Trustees bought the estate c.1630 but the first recorded lease was not until 1664. A wedge of land within the Charity's Estate was owned by descendants of Sir William Blake (d.1630) and became the Thurloe Estate when Blake's descendent Anna Maria Browne conveyed it to John Thurloe Brace, her second husband, on their marriage in 1713. He was grandson to John Thurloe (1616-1668) Oliver Cromwell's Secretary of State. Two other parcels of land at the west of the Smith's Charity Estate by Sallad Lane separated a section of the estate lands, part of Brompton Heath and later the site of Evelyn Gardens, from the main estate land. The Trustees of Henry Smith were granted building leases by an Act of Parliament in 1772. Following the Napoleonic Wars the rapid development of areas of London began in earnest, including in this area of Kensington, which the Trustees of Henry Smith's Charity began to develop in 1823, appointing George Basevi as architect in 1828 and subsequently Henry Clutton from 1845, later succeeded by Charles James Freake, later Sir Charles, who built the extensive layout of large houses here from 1865.

Onslow Square is in two parts separated by Sumner Place, the houses designed mainly by George Basevi in grey brick, with some stucco. In the south-west corner of the square is St Paul's church, also by Basevi. The two areas of communal garden were laid out in 1839; in 1928 both remained in the ownership of the Trustees of the Smith's Charity Estate that on the east is described as a 'a large and attractive open space with well-kept lawns and some fine trees. Overlooked by dwelling-houses' and that on the west as 'flanked on two adjoining sides by roads, on one side by the rear of dwelling-houses and a church, and on the remaining side by the rear of Brompton Hospital. Laid out with lawns, flower beds and trees. Well-kept and attractive.' Both were maintained by a Garden Committee and for the use of lessees of adjoining houses who paid a proportion of expenses for maintenance; in the case of the eastern portion the leases expired in 1951 and in the western portion in 1935. The original railings are still there; the gardens have a variety of ornamental trees and shrubs and grass in the centre.

Famous residents of Onslow Square include Lewis Carroll at No. 101, Henry Cole, writer, initiator of postal reform and first Director of the Victoria and Albert Museum, at No17, Admiral Robert Fitzroy, Captain of the 'Beagle' at No. 38, architect Sir Edwin Lutyens at No. 16, sculptor Carlo Marochetti at No. 34, writer and poet Sir Theodore Martin at No. 31, and novelist William Makepeace Thackeray at No. 36.
