My primary motivation for building this is to create a shaded space for my dogs to rest when out in the yard with the added benefit of providing real estate for an additional herb/bee/butterfly garden. My dogs are spoiled rotten and sleep in bed with my wife and I, this is a spot for them to rest when playing in the yard, it is not designed for a dog to live in. I had no plans and simply designed as I went, so follow along and ask any questions as needed.
Step 1: What You'll need
2x6 inch ACQ pressure treated lumber
1 inch PT CDX plywood half sheet
2 lbs 3 inch deck screws
2 lbs 2 inch deck screws
Pocket hole jig (optional)
Drill & bits
Assorted woodworking paraphernalia (clamps, cords, etc)
Most of this stuff I had laying around, the wood came from disassembled garden boxes from our previous residence, so I can not give an accurate board footage used. Fasteners should be chosen for compatibility with PT lumber.
