In this case, balance is achieved through additional head chairs. When using a rectangular table include bolder chairs at either end to make it more dramatic. I dig this look! And you just increased your seating!
I love this because it reminds me of an Italian outdoor dining room. The chairs and table are perfect. I love the simple plant and limes on the table. Simplicity but yet the finer things.
I like this patio idea. think of an italian tuscan home. I like the trellis idea. however i would have vines growing all over it. get one of those plants that will grow up the sides and have it cover the wood.
