The Marylebone Conservation Area covers the Howard de Walden, Portman and Crown estates' Georgian and Victorian terraces, mews and the Harley Street medical quarter. Works affecting its character or appearance, including most external alterations, demolition and tree work, require planning permission and may need listed building consent where individual buildings are listed.
