On the Balthasar Van der Polweg in
Delft, De Zwarte Hond designed a student housing complex with a sunken
bicycle storage facility. The building, comprising 15 floors, provides
accommodation to over 400 residents. The conscientious integration of
the bicycle shed into the landscape and the building’s extraordinary
architectural design are an enrichment for the TU campus.
Integration into the planning area
The high-rise apartment building towers over the water along the
Balthasar Van der Polweg on the TU campus. In the bank between the water
and the street lies a sunken bicycle storage facility hidden under a
roof of grass, which supports the main entrance to the complex. The
planning area is part of the TU centre area and was therefore subject to
a number of urban development preconditions, especially with regard to
the building height compared to the surrounding buildings. The area is
home to buildings of varying dimensions that are, however, in rhythmic
proportion to each other. The housing complex is not of average height
for the campus, but it fits into the surroundings because its location
and height contribute towards the rhythm of the rest of the high-rises.
For example, its construction height coincides exactly with that of the
Faculty of Architecture on the other side of the Mekelweg , and it faces
the same direction as all of the other high-rises in the area. The
position and the dimensions of the building are based on several
factors. Its location was chosen as far west as possible to leave enough
room between it and existing buildings, and the size was determined by
the noise contour of the Schie-oever. A number of interesting views were
created by designing the building to meet this contour. The building
lies directly on the street and has a prominent presence on the
Balthasar van der Polweg. The tower does not block any important views
of Delft, but instead reinforces the image of the campus as a centre of
knowledge.
Residential Tower
The most remarkable aspect of the complex are the side elevations.
Their design was mainly influenced by one single environmental factor:
noise. Because the building is located within the noise contour of the
Kruithuisweg, every apartment has a bay window with one ‘deaf’ wall and
one that can be opened. The wall cladding is white coated aluminium that
is carried through to the upper and bottom sides of the tower. This
hides the technical installations from view and the provides the façades
with a fitting finish. The end walls are made of concrete and glass in
varying transparencies and hues of green. As a whole, it is an
expressive building which, despite its contemporary style of
architecture, ties in with the Brutalist architecture of the existing
faculty buildings.
Bicycle Storage Facility
The other residential buildings in the area have evident bicycle
storage problems. This housing complex has solved the problem with a
sunken bicycle storage facility, which can be accessed through two bike
paths. The location of the shelter was chosen to cause minimal damage to
the canal banks and spare a number of trees. Only the grass roof is
visible from the street. Its integration into the landscape and the
choice of material for the entrance to the residential building (glass)
bear witness to the modest and functional solutions it provides for the
location.
