The Milljanich Spa and Patio project was one of the first times we have seen a built-in jacuzzi be such a beautiful focal point for a patio. Ralph Miljanich and Tom Ralston Concrete designed this patio and spa and the owners were thrilled with the project. How could they not be with such great views and all the tranquility that a home in the country can bring especially when sitting in relaxing jacuzzi.
