The Pergolakit.org website provides reviews and ratings for four commercially available pergola construction kits from two manufacturers. Garden Craft offers the Pergola Hardware Kit and the Redwood Garden Pergola Kit, while DC America sells the Wall Pergola as well as the Toscana Double Bench Arbor with Pergola Kit.
The two Garden Craft kits reviewed on Pergolakit.org vary by materials. The Pergola Hardware Kit contains the fasteners needed to construct a do-it-yourself pergola, as well as a stencil to modify the lumber, sold separately, to have the curved ends commonly found on these structures. Use the contents of this kit to build an 8-by-10, 10-by-12 or 12-by-14 foot pergola with any type of wood.
In contrast to the Hardware Kit, the Redwood Garden Pergola Kit comes with the necessary hardware and lumber, pre-cut to size, to assemble a 10 foot wide by 12 foot long by 8 foot tall free-standing pergola. The redwood lumber is guaranteed to be 100 percent sustainably-forested wood.
DC America offers two metal pergola kits. The Wall Pergola, not a full free-standing unit, is an accent model made of white powder-coated aluminum. It measures 10 feet long and is used over doors, windows and garage doors to provide exterior decor. In contrast, the Toscana Arbor with Pergola Kit, made of heavy-duty powder-coated steel, is a free-standing pergola that features a pair of integral benches.
