Dropmore House in Buckinghamshire is a Grade I listed 18th century house designed by Samuel Wyatt for Lord Grenville. It is surrounded by a fine collection of interesting and unusual 18th and 19th century garden buildings such as the Grade I listed Aviary, a Chinese style Tea Pavilion and a stone alcove from Old London Bridge which was brought up the Thames by barge.

The main house suffered from a series of major fires whilst the garden buildings have been neglected. GQA restored these garden buildings and gave historic building advice for the restoration of the main house, which was undertaken by Quinlan & Francis Terry.
