What Makes This Arbor Stand Out?

The metal balusters are the signature detail. Set between the posts on each side, they add a crisp, ironwork pattern against the warm, rough-sawn timber and give the arbor a finished, gate-like look without closing it in.

Overhead, arched beams with two decorative keystones and Champion beam ends carry 2″ × 8″ rafters and 2″ × 4″ shade planks. The Early American stain is a warm, medium brown that suits the green, wooded landscape around the home.

How Does a Timber Arbor Hold Up in a Wet Washington Climate?

Western Washington is known for wet winters and drier summers, so an outdoor structure there has to handle long stretches of rain and moisture. Solid Douglas Fir timbers, a quality stain finish, and regular upkeep are what keep an arbor looking good in that kind of weather.

Every Western Timber Frame kit ships with touch-up stain, and the long-term maintenance guide explains how often to re-stain based on sun and weather exposure.
