I can rule out home built just for the fact that the joints in the wood were not made in someone's backyard or cabinet shop. I've been a carpenter for 37 years and haven't seen these interlocking tongue joints for quite a few years, and only in expensive furniture. Maybe you could order the stuff pre-done,that's a probability.
I'm kind of leaning towards an electric car now only because I haven't seen any traces of an engine. Like exhaust pipe, gas line, tank, and crap like that.
And yes to answer the question about the curved glass. The glass is slightly concaved to go around the back corner. I'll try to send a picture tomorrow.
