At the heart of a Thames loop, the site lives off its relationship with the river; the tide giving a rhythm to its landscape. The master plan overlays a functionalist layout aimed at creating an ecologically sensitive development using the natural dynamic of the site. The site is divided into bands of alternating functions, parallel to the riverbank, : access/services, residential properties, green corridors for recycling (grey water and organic waste) and generating energy (wind mill) and again; alternating public , private and semi-public domain. Existing landscaped mud-beds criss-cross this system to collect recycled grey water. The diversity of typology within the development emerges by overlapping a third system – a linear park – which connects the main pedestrian accesses to the site, the train station and the main waterfront activities. Transport nodes are dispatched to give the same « global » accessibility to each part of the site, but by different transport systems (train, bus, car, boat, cycle, etc…). Uses are identified to occupy a sustainable relationship with the existing city and are organised by the typology and access definition, in such a way to generate activity (or occupancy) 24 hours a day on the whole site.
