When we were in between houses, we had a 2-bedroom apartment. The second bedroom was an office so my only work space was a glass dining table. I used a GP building board:

It was a pain but I did manage to finish a couple kits and ARF's.
Now I have my garage back and have three work benches. One is intended for non-airplane stuff but it does always seem to have kit boxes or parts stacked on it. Another isn't very flat so I mainly use it for cutting and other stuff that doesn't require a true surface. The third is just a thick, hollow 36"x60" table top I got from Ikea for $20. It is perfectly flat and covered with ceiling tile. I have it sitting on some A-frame type legs. For now this is all the building surface that I need. The ironic part is that I seem to have produced more airplanes back on that dining table in an apartment. Go figure.
