An office building, kind of like this:<br/>(http://behance.vo.llnwd.net/profiles3/173570/projects/569167/b164642e71fc5a8ed2a6c15a8e3a7f9c.jpg)<br/><br/>The way I imagine it, they're probably renting office space, so it might  be like three or four stories, with a few other offices around, one on each floor. Something like that, maybe?
