Housing Development in Trofaiach
Hubert Riess, Graz
This housing development, which occupies
an entire street block, comprises
two three-storey linear tracts with a protected
landscaped zone between them.
The strips are divided by straight-flight
staircases Ihat extend over the full width
ot the blocks. Each staircase provides
access from the courtyard side to two
dwellings on each floor. The dwellings
themselves have an east-west orientation.
All external walls and party cross-walls
are load-bearing and were prefabricated
in storey-height units. The facade elements,
extending over the full width of a
dwelling, are connected by laminated
timber beams and fixed to the floors.
The roofs and staircases are also in a
prefabricated unit construction system.
