A quiet enclave of distinctive homes, Sandy Hook was developed by its namesake, Mary Rockwell Hook. A pioneer in the study of architecture—at a time when women were considered unsuited to the industry—Hook designed the first two winter cottages in the tropically secluded community, just off Ocean Boulevard on Siesta Key. ... more.Today, Sandy Hook continues to embody the spirit of Hook's passion for art and architecture. The 42 single-family homes that share this private beach location are living monuments to that passion. For those who prefer, there are condominium residences available in the Sandy Cove section of the community.
