Standard construction techniques are used, that is, 2x4 and 1x6 studs with 4x8 plywood sheeting for the exterior. You get a full list of materials, plus a few photos and measured drawings to help you build. A cement floor is supposed to be used, but you might adapt a joisted floor if you feel it is appropriate. Finished project is 8' tall, 8' wide, and 12' deep.
