german practice amunt (björn martenson, sonja nagel, jan theissen) has sent us images of ‘justk’,
a multi-storey dwelling for two adults and four children in tübingen, germany. sitting on a 365m plot
on a south-facing slope, the design makes most of its limited size and seeks to provide imaginative
overlapping of spatial areas while remaining sustainable and energy-efficient in its domestic operations.

working with the local state building regulations, the house is built vertically to a total of four storeys
arranged in a staggered fashion. the overall volume features a number of angles that can be clearly
read from the exterior. finished in a slate-grey shade, the design relates to the surrounding 1920s
tuff buildings in a contemporary manner. the roof form was influenced by a ‘southwester hat’,
constructed out of welded sheeting which incorporates a drainage edge that leads off the ‘hat brim’.

the internal space is in essence two houses wrapped in one envelope. keeping in mind the future
trajectory of the family, the design is kept flexible and can be split into two living units with separate
entrances. wood is the predominant material for the interior surfaces, chosen for its renewable aspect
as well as its thermal qualities. the light tone of the wood maximizes the natural daylighting effect
while extending the sense of space through its singular finish. constructed in a short period of time,
the house utilized a prefabrication method with 136 elements installed together with a notching
and joinery system.
