Wooden high-rise buildings are growing in popularity in Finland and Koskisen and its partners have designed a standardised wooden block of flats for the Finnish markets. The standardised block of flats is designed to speed up projects and minimise construction costs – without compromising on quality. Several such buildings are already being planned in eastern Finland. 

The greatest effort in Koskisen Houses’ history, Europe’s largest wooden block of flats, is beginning to near completion and it is time to focus on new opportunities. Designing the standardised block of flats is the next natural step in a situation where an increasing number of Finns wish to live in wooden buildings. 

“The proportion of wooden blocks of flats is rising in Finland and will settle at 10–15% of the annual volume of high-rise production,” estimates Director of Koskisen Houses Juha Kohonen.

According to him a carefully designed standardised block of flats creates a simpler sales process and makes the client’s job easier because it enables them to get to grips with the detailed blueprints and costs of the building at the very start of the project. 

Cost-efficiency and reliability 

Koskisen’s standardised block of flats has four floors and is built out of massive wooden elements. The design of the building is focussed on minimising costs per square meter, which are, in fact, 5 per cent lower than in a regular wooden block of flats.

“For example, the space used for stairwells has been reduced in order to leave more room for the flats themselves and to keep costs per square metre at a minimum.” 

According to Kohonen, a standardised building creates certainty for the client as the timetable, costs, functionality of the building and its quality have all been considered and defined in detail. The standardised building can, of course be modified but Kohonen suggests careful consideration – are the changes necessary?

“The position of each wall, through-hole and intermediate floor has been carefully planned and optimised. Even the slightest change could cause a significant increase in costs,” he says. 

Wood construction is gaining momentum in Finnish public buildings. This is clearly demonstrated by Koskisen Houses’ order book, of which professional projects currently make up more than half.
