The project won an
invitation competition for developing four apartment blocks from 125 to 140
metres in length. The client chose our proposal for economic reasons: we
managed to provide more saleable surface on the predefined urban set-up and a
lower floor space index than all the other proposals.
The scheduled time
for preparing plans and for resolving the building work was very tight: 650
apartments in less than eighteen months, which meant more than one apartment a
day. The budget was also extremely limited: the aim was to build low-cost
apartments and we had to bring the final production cost in at around 500 €/m2.
To make planning and
construction simple and to allow for the use of such prefabricated elements as
bathrooms, windows and facade panels the buildings were designed in module
form.
Each building is
divided into four identical modules, each with its own vertical communications
core. There are 42 apartments in each module, varying from small 30 m2
studios to 1.5-bedroom 60 m2 apartments on four identical floors,
and larger duplex apartments from 85 to 105 m2 on the top two
floors. The module is repeated four times with slight variations at the far
ends of the building.
The facade is
designed in two layers, the inner facade and outdoor space being formed by
items such as glazed loggias, balconies, terraces and verandas. The second skin
is constructed with precast wooden panels, glass and metal rails. The
structure of the apartments is such that each apartment gets at least one
balcony and loggia that connects outdoor and indoor space. Like the modules,
the facade layer is also repeated four times, but given the different geometry
of the elements the repetition passes virtually unnoticed.
There are two
parking levels beneath the site. The landscape provides a contrast to the
geometrical facade through the use of gently curving rails and other features.
It breaks up the sightlines through the complex and creates a difference
between public and private space.
Sustainability issues: 1…is provided with combination of
balconies and winter gardens on the east-west elevations.
They function as constant temperature buffer zone to the main living and
sleeping areas.
Additional aluminum shading panels are placed on the outer sides of the winter
loggias and balconies.
2. The service and communication spaces are reduced to minimum thus the
daylight is provided on the shafts. The monthly basic energetic and service
costs are very low; so also economic for the habitants since the apartments are
social type.
