While you can easily adapt existing pergola plans from anywhere, you can also draw your own set of pergola plans too. Don’t forget – you can use your pergola plans when you apply for your pergola permit.
Let’s try it out.
I have in a fairly small suburban back yard with a concrete slab that extends out from my sliding glass door.It would really help out in the summer in keeping the house cool if there was some sort of shaded overhang above the patio slab. Something, perhaps, like an attached pergola.
Measure twice, cut once
My yard is small as I said, so taking a measuring tape I stand where I think the projection should be coming out from the back wall. Any further and the overhang from the rafters would be crowding my favorite tree which I really don’t want to have to trim that frequently. So, leaving a generous gap there I measure to the back wall where the ledger board would be attached. 9 feet. Considering that most end cuts create that overhang about 10-12 inches out, I make it easy on myself and say the posts should be set 8 feet out from the wall.
Don’t forget to look up!
Now I look at the length and go through similar steps. Eyeball the roof line keeping that 1 ft overhang in mind for each side. My backyard is shallow in depth, but fairly long so I decided to pull the posts out to a 10 foot span to match that shape and keep everything in balance. No potential obstacles for a total roof span of 12 feet so I am set.
My attached pergola will be an 8×10. My two 6×6 square posts will be set on the concrete patio 8 feet out and 10 feet apart. They will be 9ft tall and the beams and rafters will be placed six inches from the top leaving me well over the recommended 96 inches in interior roof clearance. That way, if I ever decide to install a fan or a lighting system of any kind there is plenty of space.
