Some embodiments include a structural building that supports attachment of modular rooms. The structural building can include one or more anchoring structures fixated to its building frame. A moveable modular room can be adapted to be detachably connectable to at least one of the anchoring structures. The modular room can be adapted with fixture features for a customized application to use the modular room. The anchoring structures can be adapted to enable replacement of the moveable modular room, as a single unit, by another moveable modular room. The moveable modular room can be a configurable room.
