Freestanding and attached arrangements
A freestanding pergola carries its loads through its own supports, while an attached arrangement needs a suitable connection to the adjoining structure. Both require a complete foundation and framing approach. The post layout can affect movement, seating and lawn access. On an existing deck, the supporting frame needs assessment for the proposed addition. Specify how the pergola is supported before choosing visible beam profiles, so the structure does not rely on an assumed connection or insufficient backing beneath the deck boards.
