	This is a photo of an early model where we actually made the columns out of western red cedar. A year later we came up with a way to anchor fiberglass columns to concrete and make them really sturdy. Fiberglass columns won the competition. This is a Freestanding Roman pergola, built with Clear lumber, 4 8 inch Fiberglass Columns and Sealed with Olympic. It has 16 foot rafters and 16 foot purlins with a 24 inch overhang, and stands 8 feet tall. Do you want this exact pergola? Simply enter your zip code below.
