I think this is a great idea and would be very useful for people who want their own FC but don't mind having a modest location. Some solo (or very very small) Free Companies would still want to show off if they have a large lot with all the trimmings, but other people would be happy with a door to a workshop off an apartment. Make a 4-slot indoor gardening box and you have the all the conveniences of a FC hall using the existing apartment code.

The more ways we have to free up housing plots without players feeling like their "stuff" is being taken away, the better.
