Managed to get some south facing windows installed. What a pain...literally. Hacking windows into corrugated metal siding and dealing with pole barn framing in an existing structure is not my idea of a good time. Give me stick built any day over pole buildings!
It turned out nice though. The windows are high, non-opening. Letting in plenty of low winter sunshine. Shielded by the eve's and leafy trees in the summer. Allowing full use of the wall beneath for peg-board and work benches. Perfect for my needs.
