Tree House Plans from Treehouse Guides

We begin by taking a closer look at three designs from Treehouse Guides, two of which are shown at the top of this post. The San Pedro tree house is affixed to a single tree, and it offers 64 square feet of floor space, including some outdoor square footage. Six windows and a landing with railings are additional highlights. [from Treehouse Guides]

Next we have the Zelkova treehouse, which is built across two trees and features four windows that let the sunlight in. A covered deck is a key feature of this eye-catching design, which also offers 64 square feet of floor space. [from Treehouse Guides]

The Outpost tree fort provides 42 square feet of floor space, and while there is no roof, this fort is surrounded by railings for safety purposes. A ladder guides inhabitants through a trap door in the floor for a grand entrance that is truly fort-worthy! [from Treehouse Guides] 

Tree House Plans with Prominent Railings

Like the fort above from Treehouse Guides, many a tree house incorporates a sturdy railing into the design. Like this Salt-Treated Lumber tree house from JCM Enterprises! The plan is easy to read, and the dwelling features beautiful salt-treated lumber. Build this structure on a solid tree base, on stilts, or on the ground:

Our next DIY tree house endeavor comes from EZ Treehouse Plans, and it features a traditional railing, as well as an abundance of lattice siding. An open layout with a front and back deck are design highlights:

Our next three tree house designs come from Nelson Treehouse and Supply. Below we see the Methow tree house (left) and the Omak tree house (right). Both plans showcase a modern sensibility, as well as a wonderfully sloped roof. Although not evident from the picture, the Omak features a large window, and it can fit a queen bed, two chairs, and a small table.

The Oso tree house also boasts a sloped roof, as well as a series of windows that welcome the sunlight and add a true retro effect to the design. This design benefits from the support of multiple trees, as shown below:
