My girlfriend's father farms in southern Sweden (near Växjö) and grows extensively in mobile greenhouses and uses them to house both his sheep in the winter, and his chickens. he has 6-10 of the same design.

Mobility: being in logging country, he mounts the each frame to two whole tree trunks running the length of the house. These serve both as weights (so it won't blow away) and as sledges, so he can drag the entire hoop house with his tractor.

Construction

This will just be a basic outline for now

• Step 1. Bend Tubing
• Step 2. Assemble Bows
• Step 3. Drill and Assemble Rails
• Step 4. Layout
• Step 5. Erect Frame
• Step 6. Attach Hipboards and Endwalls
• Step 7. Skin it.
• Step 8. Roll it.

This will be a great farm hack tool entry! I look forward to seeing the material and construction details. A video of moving it would be cool too. This is something that we would be interested in building on our farm.
