The new extension of the gatehouse accommodates ticket sales, a shop and a tearoom.
The store gives space for the cash account of the presentation of three product groups, related to Constantijn and Christiaan Huygens, Hofwijck and the garden of Hofwijck.
Because visitors enter in the same room as they leave a wall presentation gives the widest possible throughput.
The wall unit is visually one with the bank of the tearoom.
