A farmhouse on the edge of the heath was enlarged by Thomas Platt before 1811 and who gave his name to the lane.
By the mid 18th century, Platt’s Lane was running from West End and Fortune Green to Hampstead and Hendon.
In the 1830s, farm buildings were erected on Thomas Platt’s estate fronting Platt’s Lane.
On a field of Platt’s estate, four houses fronting Finchley Road were built in the 1840s in the district which was briefly called New West End.
In 1843, T. Howard built Kidderpore Hall, a stuccoed Greek revival house for John Teil, an East India merchant with tanneries in the district of Calcutta from which the house took its name. Its grounds became a private park and two lodges were added, one on Platt’s Lane in the late 1860s. The 1860 Stanford’s map labels it as Pratt’s Lane.
By 1870 the farm buildings at Platt’s Lane had been replaced by a house. Two cottages were built in Platt’s Lane in 1875 and 13 more houses between 1884 and 1886.
In 1890 Kidderpore Hall was acquired by Westfield College and the rest of the estate given over to builders. Building - mostly detached or semi-detached houses - fronting Platt’s Lane, Finchley Road, Kidderpore Avenue, and Cecilia Road (later Kidderpore Gardens) was complete in 1913.
