In Pori, there was Finnish Housing Fair in summer 2018. A Haltiatar -house is a beautiful wooden house with several Liune interior doors. This house has an efficient floor plan, and Liune doors are an importan part of that.

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.
