I made a mistake, which is that I built the apartment rooms in separate areas, each room in a project, but now I want to collect them in one place and stick them together. How do I do that, or do I have to rebuild everything in one place?
Go to individual projects, group furniture, save to favorites. Make note of room dimensions, wall coverings (RBG, HEX #) save wall materials to favorites. Take 1K renders, download to your system for reference. Then open new design and just place furniture, wall coverings/materials etc.
