No. When I very first built it fifteen years ago, the first set of construction doors around Big Bird's nest (when the model looked as it did circa 2001) could open, but not very well. Likewise, right now Oscar's can does open and close, just not very well: it's "hinged" with a tiny drop of glue on the back edge of the lid, so you can open it partially, but not all the way without it breaking off. Similar to the doors, I have often considered cutting out the window panes, covering the inside of them with clear plastic (like the kind binder dividers are made of), and actually putting together interiors, so you can actually look and see inside the buildings, but that would require me to completely gut out the buildings themselve, which may affect their foundation - not to mention I'm sure there'd be some minor, unavoidable damage to window sills and stuff from the incisions of a knife or scalpel cutting out the panes. One thing I wish I could do is 3D printing for some of the accessories I'd still like to have but can't find at any hobby store (and accessories, in general, in the right scale, are becoming harder to find): not only would I still love a couple of sets of wooden tables and chairs for the arbor (and perhaps little tricycles for under the carriage house staircase), but I'd like to replace some of the accessories I have right now, such as the mesh trashcan (which is just a thimble), fire hydrant (a marker cap, but honestly, I've never seen black fire hydrants in real life), and the postal box by the lamppost (still would like to give Big Bird his mailbox too). I did, however, recently build a new newsstand for Hooper's (it resembles the one during the ATC seasons), and a new outdoor sign for the Travel Agency, similar to the outdoor menu at Hooper's.
