For about $50 in materials, you can build this 4 ft. tall lighthouse in one weekend. The entire lighthouse is made of standard 2 x 4’s, and the square shape doesn’t require any unique angles. Make it out of regular 2 x 4’s and paint it, or go with pressure-treated lumber for a natural, wood look. The body of the lighthouse easily lifts off so you can access or hide objects in the base. Downloadable woodworking plans read like a book and include photos at every step. Instructions for painting it the Cape Hatteras theme is included with the plans.
