Adriaan Geuze as studio master and the team of West 8 made the spatial framework for De Staart as a basis for possible future developments. The Framework contains substantive principles, whereby the landscape quality of the area determines the structure. Use was made of the unique position between the Wantij and the Beneden Merwede, and of the transition from urban area to the ecological main structure in the Biesbosch area.

Within the spatial framework, an urban exploration was made with which the requested program was examined in mass volume. A total of 1.3 million m² of gross floor area of buildings is needed for 7,000 extra homes, where 14,000 people can find shelter. To preserve the human scale, a building of a plinth with 4-5 layers was chosen, where in some places up to 70 meters high can be built. To the East, housing construction is decreasing, and activity is increasing; it concerns warehouse typology buildings in which multiple functions are possible now and in the future.

The housing is combined with the development of a regional tidal park. This tidal park functions as a recreational and cultural landscape and is at the same time an important location condition for potential new residents of De Staart as a high-quality public space. More attention will be paid to walking and cycling routes and the existing residential areas will be connected to the new Dordt-track: a route that runs from the center, via De Staart to the Biesbosch. In addition, there is plenty of attention for biodiversity by transforming the now mainly hard quays of the Wantij into nature-friendly banks. The water becomes more accessible, there is room for education and play.
