In Mikkeli, there was Finnish Housing Fair in summer 2017. By the lake Saimaa there is house MinunVALO. This house is made of steel frames, and has Liune as interior door. The house itself is bright and spacious, and a door sliding into the wall increases the space even more. Beautiful black Liune doors are part of the mordern loft spirit. 

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.
