Proposals for a major redevelopment of the former Debenhams store on Oxford Street, W1, have been lodged with Westminster City Council.
The application for the empty flagship, located at 334-348 Oxford Street and owned by Ramsbury Property International Holding, includes adding two additional storeys to the property.
The scheme, designed by AHMM, will deliver around 376,600 sq ft of grade-A, class E employment floorspace, largely for office use.
It will also provide some 72,390 sq ft of retail on the basement, ground and first floors, and around 14,300 sq ft of flexible class E floorspace along Henrietta Place and Marylebone Lane.
The existing property has seven storeys, divided into 273,400 sq ft of retail space and 88,590 sq ft of office floorspace.
Gerald Eve is acting on behalf of the owner on planning matters.
