To give you the benefit of the doubt that you're really mainly intrested in using the workshop: I'm sure there are plenty FCs who dont use their workshop and wouldnt mind renting it to you.

Besides that this seems like nothing more than a thinly vailed attempt to give yourself - and only yourself, seeing how your FC has 2 members - a better shot at getting a house. Really makes one wish they'd reinstate the rule that in order to purchase a house an FC needs at least 4 (?active?) members...

I do agree with detaching the workshop from the housing, though - that way claims like "Its more important for an FC to get a house!" will become even less valid.
