Tree Top Builders designs and builds custom tree houses. We're located in West Chester, Pennsylvania, and offer services in North America. Our tree houses often come equipped with solar panels to power some lights inside - a big plus for adult and kids tree houses alike! As carpenters and arborists, we care deeply about the trees we build in, and work to minimize our total environmental impact. As tree house building experts, we not only offer full service construction, but we offer consulting, design, custom materials, and instructional workshops for contractors and other self treehouse builders.
