To build your own shady retreat, first choose a tree where you would like to sit in a quiet, secluded area, maybe overlooking a favorite part of the yard. The tree should not be tilted too much and should not have many visible roots. The method of construction is to first build the bench in two sections, then to locate the post holes by holding the bench temporarily in place.
Before You Start:
Purchase or rent a power miter box or radial saw -- something that can make precise 30-degree cuts. Measure your tree's diameter18 inches from the ground to determine the inside dimension of the bench. Use pressure-treated lumber for the posts and supports, and cedar, redwood, orpressure-treated lumber for the seat pieces. Draft at least one helper for the final assembly.
What You Need:
- 4x4 posts
- 2x4s for seats and supports
- 3-inch galvanized deck screws
- 5-inch hex bolts, nuts, and washers
