Not looking at the shape because that is hard to shoot (or interesting) but more the bamboo look Garden Shower- pinning this on Products I Love with irony. Invaded by bamboo - need to find crafts to use those long sturdy stalks.
Love the lighting under the seat. Using solar rope lights under neath would give this same effect. The design of this wall is great along with the bench lighting. This design would be easily achievable on a roof top or small backyard setting
