EXTENSION OF SCHOOL
IN ADLISWIL
It is noticeable how many schools and playschools are
currently refurbished or newly built in Switzerland. And
there is good reason: For decades, too little had been in-
vested. A building- and renovation backlog has thus
been produced which must now urgently be cleared.
Consistent designs which take adequate account of sus-
tainability, are now more in demand than ever.
L ike numerous school buildings in Switzerland, the Sonnenberg en-
semble in Adliswil, which is located just a few kilometres distant
from Zurich, had to be urgently adapted to today’s requirements and
this had to happen utilization-wise as well as energetically. In the
course of this, the town of Adliswil decided in favour of refurbishment-
and conversion measures for the existing buildings as well as an exten-
sion building with an additional six classrooms, a library and cloa-
krooms. The original school ensemble – which had been designed by
the architects Hans Müller and Peter Nietlispach in 1969 – consists of
two buildings: a school wing with a gym and an indoor pool (today the
multifunctional hall) under which an old civil-defence bunker is loca-
ted. The three-storey extension building – a design by the Zurich Oxid
Architektur office – is adjacent to the sports wing and, in line with the
two existing buildings, also consists of split levels. The levels are arran-
ged around the central staircase consisting of exposed concrete. The lat-
ter is the core of the new annex which has been constructed by using
prefabricated wood elements. In this way, the bunker, in which are now
the cloakrooms and the showers, could be used as the foundation,
which positively affects the grey-energy balance. But the decision in fa-
vour of a timber construction had yet an additional advantage which
was essential: Due to the possibilities of prefabrication, it was possible
to quickly complete the construction and to continue operating the
school correspondingly fast. The wood is, however, only visible in the
classrooms where it produces a comfortable atmosphere. The ceiling-
and the wall elements consist of spruce or fir wood, the floor covering
is strip parquet. The access areas around the concrete core, in contrast,
are designed to look entirely different: Here the floor consists of polis-
hed and sealed anhydrite whereas the walls are covered with tiles in
strong yellow and blue. “In this zone, we definitely wanted to add co-
lour to the overall design”, the architect Yves Schihin explains. But just
the two strong colours were not all. To notice the third colour, however,
one has to take a very close look – at the joints, as it were: they are red.
