the right size pergolas for decks, patios, and yards small to medium sized decks: around 12x16 feet. the vast majority of decks fall into this category. large decks: around 16x24 feet. larger decks often include more luxury features like outdoor backyard free standing pergola: 12x16 or 16x20.
the first thing you will need to know is how large do you want your pergola. as i said we will work off a 10 x 10 example. the next question we need to answer is will the post be buried in the ground or attached to the concrete. if possible i suggest putting all four in the ground. we were only able to get two post in the ground.
that's going to be one big arse beam. get an engineer to spec something for that kind of span. maybe a big glulam or steel wrapped w/1x. the biggest span i ever did on a pergola was 20', it was a 6x14 rsc. 4x8 rafters and 1x2 pine? i can't picture that looking good or lasting very long, the 1x2 pine part.
i always said we can build anythinghowever you may not like the price. pergolas are typically built in a perpendicular way with supports about 8 to 12 apart. the purpose of a pergola is to create a room without walls and offer a vertical source of interest. just the framework to frame the view.
how big can you build a pergola: several of the projects can be finished outdoors, and you won't always require workshop room to complete them.free woodworking plans are easily available on-line today. if you make plans that aren't ideal for your skill set or you might not even need to go started in any way.
despite being a bit tedious, none of the labor was really that back-breaking. and the diy price cant be beat especially when we heard that custom attached pergola kits are being sold for over 2k heres where ours wound up: truck rental to get materials home : $19; lumber: $112; post bases: $23; nuts, bolts, and screws: $46
