wow some nice set ups, you all have more storage space than me! ha ha I have a side split bungalow and still have big kids living with me so limited space for bikes. I have 2 road bikes in the basement (1 sitting on the trainer and the other for show) and then loads of bikes in the garage which is dry and insulated.
The garage is quite small so with a family's worth of "stuff" I don't have the luxury of creating a bike hanging wall or anything but is there anything wrong with just leaning them up against the wall? I do ride most of them on a regular basis (when it's not -11 C like it is now)
