Bingo! My folks and most of my siblings live in the Destin area, so I've been there a few times myself. You're up SouthBounds.
Tucson, AZ?
Ok, now I’m confused. I was pretty sure it’s was the South Pole (I had a colleague who worked BICEP2 which is next door to NOAA) and the picture looks identical to the one on NOAA’s web site:

Must be same modular building somewhere else?
This happens to me too many times... I know I recognise a place (or think I do) but can't name it in detail. I was with work to India for some 5-6 years ago and we visited a place looking very much like that. A temple? But do I remember anything more? nope...
