Plan on coming to the Open Studio this first weekend? If you give me the code word MARIO BOTTA, I have a special gift for you. Botta (b.1943), by the way, was the architect of the San Francisco Museum of Modern Art, a building that often gets mixed reviews. He designed his first home at age 16; turned professional at 27. His buildings are often brick, although he uses a wide variety of materials to create space and light.
