Good evening - I want to build a 10 by 12 pergola atop an existing deck on the sun baked side of my home. I envision a 10 by 12 foot frame of 2 by 6 pressure treated, supported on 4 six by six posts. The pergola would be covered with some sort of sun block fabric during the spring and summer, with the fabric removed in the winter because I am in a windy location. Everything will be thru bolted or lagged heavily to keep the whole thing from lifting off in a wind gust. Does this design sound sturdy enough for a windy area? Has anyone built one of these? Thanks in advance for any advice.
