Primarschule Linden Niederhasli von Graser Architekten.

It would have been possible to extend the schoolhouse in the airport community Niederhasli, which was first erected in 2003, by adding three similar modules—but in the intervening period spatial needs had changed: what was required was a hall, care rooms and special classrooms. The competition for an extension held in 2013 was won by Graser Architekten with a compact building characterised by an interior with split level spaces that can be freely divided up. The structural shell, which is visibly present throughout, provides the strong frame: narrow, pre-stressed concrete downstand beams replace longitudinal walls. Together with the parapets—also pre-stressed—they carry composite wood ceiling slabs; lightweight construction partition walls define the internal divisions. The basic grid o f 1.20 metres lays a constant rhythm over the surfaces of the different materials used for the shell and the fitting-out. [ABSTRACT FROM AUTHOR]

On aurait en fait pu agrandir de trois modules semblables du premier bätiment scolaire construit en 2003 dans la commune de Niederhasli, riveraine de l'aeroport. Mais entre-temps les besoins en espace avaient change, on devait maintenant disposer d'une aula, d'une garderie et de classes speciales. Le bureau Graser Architekten a gagne en 2013 le concours pour un agrandissement avec une construction compacte qui se distingue par des espaces interieurs librement modulables en split-level. La construction brute partout visible confere un cadre fort: d'etroites poutres en beton precontraint remplacent les parois longitudinales. Avec les balustrades egalement en precontraint, eiles portent les plafonds en bois composite. Des parois de separation assurent la repartition interieure. La trame de base de 1,2 metre donne un rhythme constant sur les differentes qualites de surface des materiaux bruts et des finitions. [ABSTRACT FROM AUTHOR]
