Here is a recent build. Dimensions are approx. 12’ long x 8’ high. Wood is all pressure treated with the exception of the post caps and trims which are cedar. Couldn’t convince them to pop for all cedar. Lattice work is 5/4 decking boards ripped to 2” wide. Holes are 2” square. The lattice work is dado’ed into each other for an assembled thickness of 1-1/8”. I left a slight reveal on each side. It’s a total of 768 dados. Took me about 4 hours to cut the dados using a simple jig (similar to box joint jig) on the miter gauge.
