FlerbostadshusSmåhus
De flesta barn i Sverige föds till småhusboende….
…vi lever som familj i ett småhus…
…vi flyttar till flerbostadshus som första egna hem….
…vi rör oss så småningom mot flerbostadshuset när barnen flugit ut…..
Här finns nu en växande industribyggsektor som siktat in sig på den
bostadsmarknad som kommer att växa i framtiden….

Weaknesses
•Weak technical condition and
energy performance
•No elevator
•Small flats have no balconies
•Dark ground floor with no
windows
•No ventilation of it is very weak
•Considered ugly, bad image of
the areas
Potential
•Good location with well
established infrastructure and
services
•Typical low density of milieu
allows additional building
volumes
•Bulky flats and rooms
•Durable and well performing
skeleton of the building BEFORE
Potential of wood
12.11.2012 Mikko Viljakainen
•Better energy performance
and surface for the building
with low CO2 emissions
•New visual appearance and
shape of the building – new
image
•Extra floor(s) and new roof
shape – income to finance
elevator and other renovation
works
•New balconies
•Hi-level prefabrication and
industrially controlled quality
of t he components.
•Very fast assembly to reduce
the harm for residents.
•Visual wood is favoured
material.
•Cost competitive.
