In 2009, the Forestry Commission, as administrator of the area, held a public competition concern- ing the design of a new Natural Activities Centre (1,100 m²) for an expected 150,000 yearly visitors. Bureau B+B, working in cooperation with HL Architecture, won Second Prize with a poetic plan in which, with casual understatedness, the condition of the soil interweaves architecture and landscape. The basis of the plan is formed by an intervention which will change the landscape: raising the water level and link- ing it to that of the Oostvaardersplassen. The large open lake that will form as a result will slowly silt up, in turn leading to a new dynamic equilibrium. Water depths, pos- sible seasonal fluctuations in water level and such weather influences as the wind will determine the ultimate form of the area. The visitors’ centre is accessible via the Knardijk, from whose elevation one can look out over the entire natural area. Small, narrow parking fields are located at the foot of the dike, between the willow trees. A 3.5-m-wide path consisting of slightly separate sandy coloured concrete railway sleepers winds it way towards the nature centre, which stands half sunk into the for- mer seabed and looks as though it has been here for years. At the point of transition from land to water, a spot where natural processes are manifest and which will al- ways be visited by fauna of many a feather, the ring-shaped gleaming building mirrors the nature around it and the constantly changing cloud patterns. In, on and around the building, a space will develop that will function as a base camp for long hikes, as a look-out point – the roof is directly acces- sible – and as a tranquil place to sojourn.
