Well in the greater scheme of things I'm not terribly worried about an office, but that's my personal judgement, other people may very well differ.
In general I would say this though. The company has a history of very little dilution, and very little debt issued. Maybe they are big spenders but this really doesn't suggest so.
I would get more worried about stuff like offices (and cost in general) if they were issuing shares left right and center.
