How to Build a Garage Pergola
Use milled brackets and pressure-treated lumber to create an elegant canopy over your garage door
The garage door is the first thing most of us see when we arrive home, so it better be a sight worthy of admiration. Impossible? Not at all: Perching a pergola upon shapely brackets adds architectural dimension and intriguing shadow lines to this otherwise utilitarian entry point. Our approach calls for mounting ready-made brackets to the door's casing—and the framing behind it—then attaching an assembly of rafters and purlins shaped to complement your home's existing trim. Follow along as This Old House senior technical editor Mark Powers guides you through making this decorative structure, which looks as good freshly installed as it would draped in flowering vines.
Brackets: Port Orford cedar Original style end bracket, about $88, and Contemporary style center support, about $55, Auer-Jordan.
