Jinso Pavilion

Extension to a catering pavilion on the Arena Boulevard in Amsterdam which was also designed by cepezed in the 1990s. Due to the scale enlargement of the entire area during the last decade, the Municipality of Amsterdam requested the owner and operator to invest in high-quality expansion. The original building, an elongated two-storey box of twenty by eight metres, has been integrated into a fully transparent glass oval measuring 43 by 30 by 12 metres. On the ground floor, the main volume has a two-metre constriction, while the first floor has a gallery more than four metres wide. The façade consists of insulation glass which was cold-bent on site. On the ground floor, the façade can be opened over more than three quarters of its length by means of a facetted folding wall. The façade accommodates three stability crosses, two of which are situated at the heads of the oval. These locations are also used for the organization of the stairs. The roof construction is more than 2.5 metres high and comprises eight large pneumatic cushions mounted on a refined detailed steel construction of facetted deltabeams. Each of the cushions consists of four layers of EFTE with three air chambers in each cushion. The EFTE bears a pattern through which the sun and light resistance can be regulated by a change in pressure in the innermost chamber. The air supply for the cushions is integrated in the construction. A cooling patio has been integrated in the roof for the building-related installations that must have contact with the outside world. The paving of the boulevard continues on into the pavilion. Embedded in large plant pots that were cast in the floor at the time of construction, the greenery appears natural and self-evident.
