Freestanding Pergola
A freestanding pergola is supported by at least four posts and is not attached to any edifice or structure. Because freestanding pergolas are not anchored to walls or buildings, their columns must be firmly mounted – usually in concrete footings.
A freestanding pergola is also called a 'self-supported' pergola. Supported by four posts, it is totally independent from the house. In contrast to lean-to pergolas, freestanding pergolas are not attached to the house, which will avoid damaging the exterior walls.
