This thread was bumped from 2012. We were just getting ready to move from a duplex (800 sf) to a three story house (1400 sf). For a family of five, the house is small by American standards, but the size has been comfortable for us. One attraction was a bedroom for everybody, whereas my son and DIL had been sleeping in the living room at the duplex. Weirdly, my young grandso thinks his bedroom, alone up on the third floor, is haunted. So he sleeps in the living room, and we're back to square one on that issue. Living with a young family after being alone for years has both challenges and rewards, but mainly it's a blessing.
We have no garage, unfortunately. The one car sleeps in the driveway. There is a door off the driveway onto the basement stairway landing. That's mainly I where keep my bike. Sometimes I lock it to the porch railing for short periods. My son left his son's bike unlocked on the front porch for a few minutes and it was stolen. I told him that would happen, but did he listen?
So how much housing does a cyclist need? Our small house has been very comfortable, with three riders in the family. The location, on the other hand.... But that's for a different thread.
