A free-standing pergola utilizes the traditional post and beam construction, and is often used to create the feel of an open-air outdoor room without requiring external supporting walls for securing. Since it is a stand-alone structure, it can be erected virtually anywhere and is perfectly suited for entertainment areas, outdoor living rooms, and to provide coverage over hot tubs, decks and patios.
Attached pergolas are attached to an existing structure or building such as your home, poolhouse, or a deck to support one or more of its four corners. Often serving as an extension of the home, they can provide additional living space and offer a charming transition from the house to your garden or yard.
A colonnade pergola balances the rafters on a single beam rather than spread across two beams. This type of pergola is often used as an aesthetic structure to define an edge, provide some privacy or to accent the landscaping.
