In Kouvola, there was Finnish Housing Fair in summer 2019. A Talo Unto -house is a compackt and ecologically built house from Sievitalo. This rewarded house has several Liune doors. Beautiful white milled Liune doors in toilet and walk-in closet. 

Liune door leaf slides inside a normal-sized partition wall. So it does not need that thick of a wall, just an ordinary one is enough. It creates more space because it doesn't need to turn. Building with Liune is efficent and controlled.
