I plan on making a greenhouse for my garden...but it could probably work for a small shop too...
Some of the lumber I've gathered. The grey boards in the left pic are "manufactured" lumber I got from a contractor just before he dropped them in the recycle trailer.
These are two 4' x 8' double pane window units I got off freecycle. They were from a remodel, and are still in great shape. I got the smaller sliding windows, and screens too. I plan on using them on the sunny side wall of a 20' x 18' building.
These are three 4' x 8' units. I plan on using 2 of them on the roof.
I got the smaller sliding windows, and screens too.
I plan on a wood floor, electricity and water in the bldg. The site is about 15' to 20' from my garage/faucet.
All I need now is better weather to get started.
