Transform Your Garage Door Into an Architectural Feature With a Custom Pergola

How to Build a Garage Pergola | This Old House · 4:41 · Video: This Old House · Watch at the source

In short: A garage door is often the first thing you see when arriving home. This video demonstrates how to elevate this utilitarian space by installing a decorative pergola, adding architectural dimension and shadow lines using milled brackets and pressure-treated lumber.

Senior technical editor Mark Powers guides the installation process, which involves mounting ready-made cedar brackets directly to the door's casing and the framing behind it. The structure is completed by assembling rafters and purlins designed to complement the home's existing trim. The finished pergola provides a visual upgrade that can stand alone or be draped in flowering vines.

The project requires specific materials including three 12-foot 2x4 pressure-treated boards for rafters, six 8-foot 2x2 pressure-treated balusters for purlins, and three cedar brackets. Essential hardware includes 3-inch and 2-1/2-inch deck screws, acrylic adhesive caulk, and wood plugs for a clean finish.
