Mr. Dougherty, who is now in his 60s, has a portfolio of over 200 amazing pieces from houses that look like a grove of trees to large pavilions that seem to have been built by a beaver. We call it art, but he calls it “stickwork.” That’s also what he named his book of thirty-eight of his most eye-catching these works which was published last year. Check it out here.
