Your lucky your going to be able to have a dedicated room for them 🙂 I currently have to store my bike in the hallway, right behind the front door, much to the annoyance of my GF!
Fortunately, I have a Dirtworker so I take that with me in the car when I ride and wash the bike after as so to not get all crap in the lift and flat when home. Been a god send over the winter as I would not of been able to see to clean the bike in the car park, and the last time I tried to clean it in the bath it didn't go down too well! 🙂
