CORTEN STEEL TALL PLANTERS - Two planters side by side with about 2' separation on east and west side planted with tall grasses to block view shed of neighboring rooftops. Planters are 38'' long and 30'' tall. Two more would be placed directly side by side on southern wall and planted with tall colorful annual plantings.
I'm waiting on some engineering requirements for the sails, but a secondary idea would be to incorporate one of these large cantilever shade umbrellas into the layout. It's easily retractable and would make for a quick and easy shade option in lieu of the sails + reinforced hardware. It would also come in at a better price point! Various styles and colors available.
Matching Corten Steel black planters to replace the two basin location where along the southeast corner and northwest corner. Tall interest (small tree form) would be planted on the northwest and current interest on southeast corner would be transplanted into this new matching basin.
