Definitely. Perhaps make it have some options (+ lock option): Everyone can build on it, no-one can, [List of IDs] can build on it (e.g. RPGs where X owns the house), [List of IDs] + Trusted can build on it (like they own it), etc.
Also a "Ownership Can" which lets you make a lot of bricks pre-owned at once would be nice. When you use it, the GUI comes up, then when you click OK after setting options you get the item in your hand.
