John,
For the trellis over the kitchen patio long edge, we want same style as the trellis over the garage but longer slats on top if needed so fully obscures the heater as much as possible.
OR we like this simple style which is complementary to the over-garage style. This might functionally work better?
We are thinking along that long edge of the kitchen patio where we had drawn bushes that to solve the problem of the grade needing retaining walls then it would be great to build a planter box there on the outside edge of the patio and string some cable wiring between the trellis posts and grow up crawling flowering plants from the planter box onto the cable rails.
