You do have some interesting questions here about hypotheticals if one was to try to build something like this.<p>Yes, these hallways you would probably not want to carpet if you expect people to ride in them with dirty bikes. They&#x27;d probably be something easy to clean like concrete or tile or plastic.<p>I think that children playing would probably get priority over bicyclists much as such things happen in neighborhood cul-de-sacs.<p>Also, if there is some explicit ownership of the &quot;bike parking spaces&quot; in front of&#x2F;near a unit then I absolutely would expect people to use them as they see fit, including things like planters, assuming such things don&#x27;t impede the other uses of the hall (biking, walking). Most buildings consider hallways common space that units have no ownership of. There&#x27;s nothing wrong with maybe giving some ownership to part of a hall. It could add to the sense of community of the building. (In my own condo building our car parking spaces are owned by unit owners, so our spaces will sometimes get used as temporary workspaces or child toy storage zones when our cars are out parked on the street, so long as we don&#x27;t block other spaces and stick to our area. If I decided to set planters on my space while my car was in the shop, I certainly could.)
