Ainger Road lies along the boundary of St John’s Hampstead, a parish which saw rapid development in the nineteenth century.
The name commemorates Thomas Ainger, vicar of St John’s from 1841 until his death in 1863, who provided clinics, schools and churches to go with the new houses in the area. Until 1882, this was Windsor Road.
George Pownall was the builder/developer responsible for developing the street. In 1868 Pownall proposed to build several new roads. After building in Albert Park and Oppidans Road
, Ainger Road was built in 1869. By 1879, Pownall had built 38 houses, three stables and a workshop.
