This garden was laid out as part of the Edwardes Estate in the 1870s. In the early 1970s the square became a conservation area and the garden was part of the 1851 Kensington Improvement Act. Christopher Fair designed the present layout with children's play area added in 1980. Anna Surdacka from Charles Wood Landscape Design, has cared for the garden since 2012.
The stucco-fronted terraces are complemented by the grade II*-listed Flemish-style red-brick houses. Dame Ninette de Valois, founder of the Royal Ballet, lived at 23 and ran dancing classes in the ballroom. Choreographer Sir Frederick Ashton, actor Sir John Gielgud, and members of Pink Floyd also lived in the square and Number 21 was the home of the National Poetry Society.
