John Ashburnham – who came from a Sussex family of “stupendous antiquity” – acquired the land here as part of a substantial inheritance in 1755.

His new set of possessions included the Chocolate House, which stood on the brow of Blackheath and had gained its name from tastings of drinking chocolate held there when the beverage first came into fashion.

The Chocolate House was unimaginatively renamed Ashburnham House in 1820. From around this time the family laid out streets and housing to the north-west of South Street, with the scheme gaining full momentum nearer the middle of the 19th century.

Much of the little estate consisted of tasteful stuccoed terraces, together with several pubs, including the Guildford Arms and the Ashburnham Arms, nowadays known locally as ‘the Ash’.

In the 1880s the Ashburnham family began to sell off the estate in stages and Ashburnham House was demolished to make way for further development. Blackheath high school opened on Catherine Grove in 1904. The school was converted to apartments just under a century later and three new houses were built in the former playground.

Most of the Ashburnham Triangle’s original housing has survived unspoilt, although the enclave was one of last conservation areas to be designated in Greenwich. The Greenwich Forge, at 62 Guildford Grove, is a wrought iron worker and blacksmith. On Catherine Grove, Maurice Drummond House, formerly an accommodation block for Metropolitan Police officers, has recently been converted into a ‘boutique hotel‘.

Thriller writer Edgar Wallace was born in 1875 at 7 Ashburnham Grove, which now displays an unofficial plaque. Wallace’s unmarried, show business parents offered him up for adoption when he was only nine days old.
