What a pergola involves

  1. 1
    Posts and base

    Posts set in concrete (or on a patio) carry the frame — the structural part that keeps it stable.

  2. 2
    Frame and material

    Timber is cheapest and warmest-looking but needs maintenance; aluminium is low-maintenance and modern.

  3. 3
    Roof options

    An open frame gives shade and structure; a louvered or covered roof makes the space usable in the rain — for a higher cost.

A pergola defines and dresses an outdoor seating area, lifting garden photos on a sale for relatively little. Timber suits a traditional look on a budget; a louvered roof turns the space into an all-weather room — match the spend to the property.
