Love this design, "Estrella" or "Star" by Jennifer Asher & Mario Lopez of TerraSculpture.
It's crafted from powder-coated aluminum and the size is 21" high, 44" wide, and six inches deep. Great for any modern garden.
It's 22" high, 40" wide and 10" deep. And of course the artistic team will fashion custom sizes if you desire.
These are just a few of the current offerings ... see all of them at the TerraSculpture website.
