Upgraded Rooms & Appartments + link them

Right now FC house rooms & Appartments have a fixed size.
If I'm not mistaken FC house rooms are smaller (they should have the same size!).

When someone builds a room in an FC house and they leave that FC, their room should automatically be moved the the apartment complex and when they rejoin another FC after that they should be allowed to move their room to the FC again for easier access (+ no loss of items when you fail to login in time if kicked from an FC when you have a room).

Also, players should be able to choose 3 sizes based on the housing idea when buying a room/appartment.
Small (the standard), Medium or Large. With the difference is that Appartment/rooms have no stories like houses do.. just 1 main floor.

Implementing this idea should lessen demand on housing since a medium floor counts as 1 small house and a large floor would count as a medium house in terms of total size.
