Our invention calls for a simpleton four-post structure, ideal for covering a humble patio or providing an command processing overhead time shelter for a garden bench. The purpose is quite simple : four upright 4×4 posts ; two horizontal beams made from pairs of 2×6 lumber sandwiched around each stake at the top ; a serial of 2×4 “ rafters ” spanning the joists and running perpendicular to them ; and ultimately, 2×2 lattice strips running across the rafters. The result is an overhead shield social organization that offers pleasing dappled shade or a base to support a canopy of vines .
The Basics of Arbor Construction
Building this arbor will be simplified if you keep in mind five steps in the construction process :
- Digging holes for four post foundations
- Embedding 4×4 posts into the holes with concrete, aligned so they are perfectly upright (plumb)
- Sandwiching pairs of 2×6 crosspieces to serve as beams around opposite pairs of posts at the top
- Installing 2×4 “rafters” to span across the sandwiched beams
- Installing 2×2 lattice strips as an open roof surface over the rafters, aligned so they are perpendicular to the rafters
The costs of your arbor can vary well depending on the size you choose to build and the type of baseball bat you select. A 6×6-foot arbor built with pressure-treated ache log will be well cheaper than a 10×10-foot spindle built with high-grade cedar or redwood lumber. If you are building a larger spindle, the size of the morphologic lumber may need to be increased. For case, a 12×12 arbor or larger may require 6×6 posts, 2×8 or 2×10 beams, and 2×6 rafters .
While the skills required are not particularly unmanageable, some preciseness is required to erect the posts so they are perfectly plumb and to secure the beams and rafters in place. This work will be well easier if you have two or three helpers to assist you .
Before Getting Started
In our model, we are building a 7- to 8-foot-tall arbor with an capable space of 8 feet square between the posts. Over the beams, six 10-foot-long rafters spaced 2 feet apart span across the social organization. last, over the rafters, there are 11 2×2 lattice strips to form an open grid as a ceiling.

however, you can ( and should ) adapt this blueprint to your own needs, adjusting the materials list as necessary. Your costs will be less if you choose to build a smaller arbor, such as you might use to cover a minute walk .
Make surely to choose log that is repellent to decay and insect damage. The least expensive alternative is pressure-treated ache, which has been impregnated with chemicals to hinder decay and insect damage. Pressure-treated lumber can be painted or stained after a short period of drying. other, more expensive alternatives include cedar or redwood, both of which have a natural resistance to decay .
