The Abacus apartment block is situated along the Amsterdam-Lelystad
railway line at the head of the waterway ‘Havendiep’.
The building comprises of two volumes: a horizontal volume containing
parking and storage facilities, and a vertical volume, nine storeys
high, with two apartments per storey. In relation to the substructure
the nine-storey main volume is slightly elevated and provides a free
view of the ‘Havendiep’ from the street side.
Due to noise prevention the facade facing the railway line and the
adjoining head facades had to be constructed as so-called ‘mute
façades’; fronts without parts that can be opened. This
leads to a very specific housing concept:
The supporting structure, lying in a longitudinal direction, divides
the apartments into two zones: a utilitarian zone containing the bathrooms,
storage areas, circulation, open kitchens and entrance halls, and
a living / sleeping zone.
The regular openings in the west façade and the inner supporting
structure correspond exactly with each other. This enables the placement
of separating walls without disturbing the main spatial organisation,
gives freedom to arrange the living space and allows to determine
the number of rooms individually. The technical installation system,
including the air heating, is designed with that aim.
The west façade is determined by the horizontal appearance
of the balconies, which provide every apartment with more than 40
m2 of exterior space. Movable glass screens allow individual protection
against sun and wind.
