My neighbor has this enormous dog house "skeleton" wood frame he started. It's got a great raised wood floor, the framing of the walls will allow for me to have ventilation, it's a great little project! He made the main frame and never finished it, it was supposed to hold two large dogs but they got rid of the dogs. It's your typical dog house shape- with the peaked roof (I hope that makes sense)..etc. What I don't know is what to use for the walls and roof. Would plywood work for the walls? How do i measure? I'm not sure where to start measuring to decide what size materials to buy. Not only the walls, but what about the roof? Where do I measure to and from in order to leave room for whatever is supposed to hold the top of the "peak" where the two sides of the roofing meet? I plan to cover over the ventilation areas with hardware cloth, and screwing walls on doesn't seem that hard if I can figure out the measurement thing. Also, how thick should the plywood walls be? The roof is the most confusing part for me. My big horse-stall-coop is covered with metal corrugated roofing, and it stays pretty cool in there- BUT this is a lot smaller... Also, I don't know how to attach the roofing either. Doesn't seem like you can hammer nails through the metal or plastic roofing, can you? I've built some little tractors and stuff, but i always throw it together as I go, and want to do this one right. But not knowing how to measure correctly kind of messes things up!
