The proposed dynamic transformation model for the Wijnhaven Island is a zoning scheme to balance out the market's demand for maximum building capacity and safeguarding a quality standard for the urban appearance. It is not a design but an open-ended strategy, a variant of the American' zoning laws' – an attitude of laissez-faire.
The model's development rules ensure a balance between new and existing development and satisfactory views and sunlight levels on the island itself. The regulations stipulate that the current block structure must be maintained up to a height of 20 metres. As an essential testcase for the later municipal high-rise vision, this concept was referred to as the 'Rotterdam layer'. High rise buildings may be built above this level under certain conditions. These conditions concern ownership boundaries, daylight access, sunlight, views, setbacks, and wind nuisance. The internal spaces in the buildings have the greatest possible flexibility to allow programmatic recycling.
