I worked on a design (only as a hobby) for a group of units in a pentagon or hexagon shape that would surround a central room. The landlord can quickly sheetrock over some doors while cutting others open. The idea is to be able to expand or contract units to accommodate different tennants. The most hilarius objection I could imagine is "nobody can have 2 refrigerators and 2 kitchens," coming from my brother who spent a fortune to renovate for exactly that. A second laundry room can be handy, as can a second bathroom. A third laundry room can be converted to a closet with minor work to cover the washer/dryer connections and some shelves. The central area would be another bedroom that has one doorway cut open and all the other doorways sheetrocked over. One last thought, if you have never considered buying a duplex for a growing family and cutting in a door or two between the sides, you should. The "you can't do that" usually turns into "that's so cool" after a few hours.
