Every building I've seen at Microsoft is big enough, although some are (or are being switched to) open-plan.

Now that I think about it, everywhere I've worked there was enough space so that everybody working there at the time could have had an office.

As to where I'm going to find them: I'm probably going to filter out employers that can't make enough money with programmers to afford an office for each of them. I know this removes a non-trivial number of employers from my potential field of employment options.
