Its 30ft sq. I set 16 telephone poles in the ground, 6 to 10ft above the ground. That had been already done. I took 3 by 4s 10ft long and spliced them together to make a good 40ft, for a overhang in the front. Had the holes drilled and all myself before today. Today, my boy, 2 nephews, a neice, and her boyfriend came out to help bolt them up to each other then to the designated area at the top of the poles. Put together, that made 4 rows of them going N and S. we also put 2 of the same together on the ground 32ft that will go on top of the 4 that the tin will go onto. They run E & W Thatll take 10 total of them. The wood was so hard it couldnt be nailed, and so we had to drill and bolt it. 128 holes today just to put up the 4 pieces and bolt them to the poles. then another 16 holes for the 2 that goes crosswise of them that we got done for the top that the tin goes on. Im wore out, but I had fun.
