3 Customer opinion Vähintään Satisfaction tyytyväisiä rate % FWR/TTY survey 2011: 6 buildings from Flats 157 (24 % of all) 118 answers (75 %) Owners 58% Rentals 42%

4 Population breakdown by age in relation with Housing Här finns nu en växande industribyggsektor som siktat in sig på den bostadsmarknad som kommer att växa i framtiden. Småhus Flerbostadshus De flesta barn i Sverige föds till småhusboende. vi flyttar till flerbostadshus som första egna hem. vi lever som familj i ett småhus vi rör oss så småningom mot flerbostadshuset när barnen flugit ut.. Lähde: Hans-Erik Johansson, Träbyggnadskansli

5 Block of flats are needed more because... Vi minskar våra ansvarsår År 1920 Personer födda mellan 1945 och 1954 tänker i första hand förverkliga sig själva (Källa: Kairos Future) Barndom Befrielsetid Frihetstid Ansvarsår Ålderdom År 1960 År 2000 År ålder Lähde: Hans-Erik Johansson, Träbyggnadskansli

6 The population group, which typically lives in block of flats, is growing. Vi skapar oss mer frihetstid År 1920 Åren i livsfaser där man i hög grad lever singel och i flerfamiljshus ökar Barndom Befrielsetid Frihetstid Ansvarsår Ålderdom År 1960 År 2000 År 2040 Livstid och livsstil där boende i flerfamiljshus dominerar ålder Lähde: Hans-Erik Johansson, Träbyggnadskansli

40 Renovation of old blocks of flats is significant potential Mikko Viljakainen

41 Case example of new fire codes present situation 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 BEFORE 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 Mikko Viljakainen

42 Potential of wood Better energy performance and surface for the building with low CO 2 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. AFTER Mikko Viljakainen
