Greenhouse

Greenhouse is nominal 10X20. Internal square footage 192.6 sq-ft so no permit required (< 200 sq-ft). Modifications planned:

1. No metal on vertical walls since sun light is desired at all levels. Planting will be directly in the ground as well as in cedar boxes an on shelves.
2. Let in (mortised) 1x4 diagonal bracing to provide strength since no metal will be used on the verticals.
3. Two windows in the back wall (truss). Not sure yet where to source these - suggestions please? Might build them from scratch.
4. Dutch door on the front wall so that the top half of the door can be opened in combination with the back windows to allow air flow the length of the greenhouse.
5. Metal flashing on the exterior corners just for a nice finished look.
6. Has a 6 x 6 preassure treated (rated for ground contact) perimeter foundation. All other wood ,except the diagonal bracing is pressure treated rated for above ground. Finding 1 inch pressure treated wood seems impossible.
7. Ridge poles will be 2x6 so that sloping joist hangers can be used to attach the rafter legs to the ridge poles.
8. Will have a middle truss so that two 10 ft ridge poles can be used. I believe finding a nice straight 20' pressure treated 2 x 6 would be difficult or impossible.

Will add more photos as the build progresses.
