Renovation of old blocks of flats is significant potential 12.11.2012 Mikko Viljakainen
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 12.11.2012 Mikko Viljakainen
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 12.11.2012 Mikko Viljakainen
