Heritage to advise on transport issues related to planning application for proposals at Marble Hill Park within the London Borough of Richmond upon Thames. 1.2 The site is situated to the south of St Margarets and is bordered by Richmond Road to the north and the River Thames to the south. The location of the site is shown in Figure 1. 1.3 The site is set in 26.7 hectares of parkland known as Marble Hill Park, within which Marble Hill House is situated.

Following submission of the application, comments were
