Located at 10 Riverside Drive, Mitcham, the proposed scheme retains and reuses 2 existing buildings on the site. Wandle House – a Grade II listed building and an existing office block, both are converted to residential use. The development consists of 25 residential units.

Retrofit First

All exteriors of Wandle House will be retained. The existing concrete frame of the office building will require adaptation and extension in some areas to make the proposal function well. The façades and windows to the office building will be updated to improve thermal and airtightness standards so they meet the current regulations. A mansard roof is proposed at the fourth level of the refurbished office building, echoing the existing listed building.


The Link Building

A link building connects and provides entrance to both buildings. The new structure of the link building will be pushed back from the street side – enhancing the visual separation between the listed building and the modern block. As well as serving as a climbing frame for planting that will further disguise this new addition from the road.


The rear of the site contains a landscaped shared garden which will provide the residents with 140sqm of external amenity space. The roofs of the main building and bins and bike stores will be covered with an extensive green roof. The landscape design aims to connect the scheme to the existing landscape of the River Wandle and Watermeads beyond.

8 residential parking spaces will be provided, including 3 for blue badge holders and over 45 cycle spaces for residents and visitors.

This proposal provides an opportunity to reinstate and celebrate the dignity of the listed building through careful consideration of its refurbishment
