These downloadable DIY lawn lighthouse plans include illustrated, step-by-step instructions, a materials and tools list, and construction photos to guide you through the build. They’re written in a book-like format rather than as blueprints. Most designs use about one sheet of plywood, though some require an additional half sheet. For painted lighthouses, MDO plywood is recommended; exterior ¾-inch plywood is another option. Finish your lighthouse with a Chesapeakecrafts top or beacon, or add your own post or pathway light.
