I am looking to build a 1/2 pipe for my boy since we have no hard top out here in the country (A-gravel drive). These plans are for a pretty large structure but it would give him some room to play. The issue is the expense, exterior plywood alone is around $570
My thoughts are to make it 4' wide instead of the 8' design but I am not sure if this would be wide enough.
Anyone ever built something similar? Any suggestion to cut down on the cost?
