Keeping up with grasshopper things, there is a sliding door that can be between room in very little amount of cases. It is quite common to design such things in grasshopper community. However, it is very difficult to be realized in a real world.
This design is not so difficult to implement. However, its usabily is very questionable. Perhaps, automatic doors with this structure could be working for some spaces.
In addition, there is a Human UI part to play with the model outside off Grasshopper and Rhino. It's very simple and I encountered a problem of inability to represent multiple meshes in dynamics using 3D View of Human UI.
All definitions in Grasshopper are this size
