Just because you use the garage for hauling the bikes does not mean it is wasted space. After removing our toys, the garage becomes our second living room, dining room and second bedroom. The bed retracts to the ceiling leaving open floor space. I mounted the table brackets in the middle of the floor (flat style) and we set up the table for eating. When finished, the table is taken down and the room can be used for sitting. (We carry two office chairs) And, when bedtime, we lay down the chairs and lower the bed just above them for the bed.
We like having two separate spaces because after 34 years of marriage, sometimes separate spaces and television channels are nice.
