A small balcony can offer a peaceful refuge.
In this example from the German site Living at home the focus is on natural materials. Wood furniture, potted plants in baskets, colors: Shades of brown and green. The cushion covers are of raw silk and strips of woven leather. A lime green barbecue grill completes the picture. (No idea where one could find one here in the US, but it’s a nice touch.)
Decorative bundles of grass add a feel of nature without taking up much space.
