Designed for a prominent urban site on the occasion of
the European Housing. Expo 2001, Calatrava╣s residential tower for Malm÷, at
the city╣s west harbor, is based in form on his sculpture Turning Torso.
Conceived to enhance and enlarge a public area defined by the intersection
of two main roads, the Turning Torso building is meant to be seen as a
free-standing sculptural element posed within the cityscape.
In the original sculpture of Turning Torso, seven cubes
are set around a steel support to produce a spiral structure, which
resembles a twisting human spine. In the Turning Torso building, the
spiralling tower is composed of nine box units, each of five floors. The
equivalent in the tower of the sculpture╣s steel support is the nucleus of
internal elevators and stairs, through which the box units communicate.
Each box unit is a │sub-building▓ of about 2200 square
meters (23,650 squarefeet). Each floor of the box unit can accommodate one
to five dwelling units will be used as observation decks for the tenants.
Space in the spine unit may be used either for a distinguished residence or
as a common areafor tenants, providing facilities for meetings, parties,
saunas, gyms or technical spaces. The two sub-basement floors will be used
for technical spaces, laundry and storage areas.
A corridor located at first-floor level will connect
the tower to a secondary building. This adjacent building will have shops at
ground level, together with parking and tenant storage rooms. The three
upper floors will be allocated for parking. A hanging fašade will create a
covered arcade in front of the shops, providing a comfortable and pleasant
zone for pedestrians.
The entire building will be handicapped accessible and
features a highly advanced environmental design. Moreover, the engineering
will allow for an extraordinarily efficient method of construction. After
the sub-basement is erected as a conventional concrete work, the vertical
circulation nucleus and slabs will be put up using a sliding framework
system. The exterior steel structure will then be attached, using elements
that were prefabricated in the shop. Finally, cranes placed on site will
pull up the in-shop, prefabricated facade. Construction time will be
substantially reduced with this method.
