I'm new to building things for myself but I tried and I have new respect for the people who do this for a living. I saw a design in a book and it called for 4 by8 beams with a box of the same around the perimiter of the patio and a checkerboard pattern on the inside, and lattice panels held in place with 2 by 2's. I have 19.5 foot square and have posts every 10 feet around the perimeter of 4*6's i have 4*6*20 treated beams going across held in with 6 inch lag screws 3 for each beam on each side and i have one of those every 45 inches. The plan calls for 4*6's to be cut and placed the other direction held in with angle brackets. is that to much weight to be held up without a post in the center of my patio (where my table goes) if so does anybody have any solutions to this problem.thanks in advance
