Roehampton Great House originally stood on this site, built in 1625 for the Lord High Treasurer of England under Charles I. Some of the foundations are still visible in the cellar of Grove House. James Wyatt built the present house in 1792 for Sir Joshua Vanneck. Now part of Roehampton University, the beautiful listed grounds of Grove House were first laid out in the 18th century.
Downshire House was built around 1770. The owner from 1912 to 1920 was Sir Stephen Herbert Gatty. In his time, extensive formal gardens were laid out, of which a small part survives to the north. In 1949 Downshire House was the last of the Roehampton villas to be used as a private residence.
