I built this Pergola in a weekend with a helper. I remember it was about 108 outside. One of the hottest stretch of days that summer but we kept hydrated.

Its is built using rough cedar for everything and I had to dig piers and pour concrete the first day. While that was curing we cut and stained all the 2×12 cedar boards then we were able to stand up the 6×6 cedar posts  and get them stained before we set the header support beams this way the wood is protected behind and in front
