Hi All, I have a few larger then our usual pergola builds coming up and trying to minimize my support to the out corners. How can get 18ft span out of 2x8 or 2x10. I'v gone as far as 16ft with 2x8 dbl's but with 4x4 block sandwiched in between which matched the outside 4x4 corners were the cedar was attached to the non notched 4x4 post also have notched and filled in the space with a block as well to keep it locked up. I was expecting to have call backs for saggy cedar but still no call backs and still keep in touch with clients.
Remember I'm in the city so we keep the designs very simple and clean here.
Feel free to post picts I'm sure we would all appreciate some deck****.
