In 1987 the exhibition 'Nieuw Nederland' (The New Netherlands) took place on the initiative of the foundation Nederland Nu Als Ontwerp (The Netherlands Now As Design) with the city planner Dirk Frieling as chairman. With a view to the future urbanisation of the Netherlands, four scenarios were developed for the spatial development of the Netherlands up to the year 2050 in order to make the urgent choices transparent to politicians and the public.
The four scenarios met different political visions of the future: 'careful', 'critical', 'dynamic' and 'relaxed'. The first three sated the wishes of the three main streams in Dutch politics at the time, those of Christian democracy, social democracy and liberalism, while the fourth offered a problem-solving 'technocratic' approach, elaborated by the initiators of the event.
For the 'relaxed' scenario Peter Terreehorst designed a new landscape in Zeeland inspired by the monumental delta works that protect the delta landscape of former estuaries and islands from the natural impact of the North Sea. The Terreehorst plan combines issues of food production and sea defences with dynamic landscape formation to meet seemingly opposite needs. In a series of steps the plan worked towards an assembly of 'fast breeding ponds' for fish and shellfish (so-called maricultures), recreational areas and residential areas. Together, these steps would result in an ecosystem that would make the southwestern Dutch delta future-proof on all these aspects.
Urban planner Joost Váhl (1939) made a name for himself as an activist and advocate of the mixing of traffic where the dominance of the car had to be curbed while pedestrians and cyclists were given more space. In Delft he laid the first speed bump in the Netherlands.
In 1989 Willem Jan Neutelings (1959) was commissioned by the municipality of The Hague to study the urbanisation process of the southern section of the so-called Randstad conurbation in the west of the Netherlands, in particular the area between The Hague and Rotterdam.
The Rotterdam office Van den Broek and Bakema made the first design for the Tanthof residential area south of Delft in 1969. The plan provided a core of high-rise slabs along and over a major trunk road towards Rotterdam, with the low-rise neighbourhoods around it.
Gonggrijp graduated in 1969 on a landscape study of the western Netherlands. His design research focused on the ongoing expansion of the port of Rotterdam. For this research he created a series of hand-drawn maps with overlaid transparent sheets.
