From the Ground Up
One of the most exciting challenges of treehouse design is finding ways to build large structures supported by trees. While sometimes necessary, incorporating posts to the ground can affect a treehouse’s aesthetic appeal, limit “play space” beneath the treehouse, and even run the risk of damaging a tree’s root system. Nonetheless, Tree Top Builders strives to minimize the use of ground support posts in all of its design/build projects.
Implementing Glulams Into Our Builds
Using engineered glue-laminated structural timbers, or “glulams,” greatly assists us in this goal. Glulams can be manufactured in various ways, furthermore allowing us to engineer and build two-story treehouses with no intermediate supports. TTB custom-designed brackets and gusset plates can also allow us to connect glulams and trees in various configurations. Additionally, these brackets and plates can be tailored to the structural requirements of each unique build.
We have recently begun to manufacture composite beams in-house, purchased through local hardware suppliers, up to 20 feet. These composite beams are also compatible with the same brackets and gusset plates used in our glulam elements. These elements are available from Treehouse Supplies, along with instructions on making these beams yourself.
