How the Building Process Works

Building a deck or pergola involves several key steps to ensure a durable and visually appealing result.


First, the design is planned, considering the property layout, intended use and aesthetic preferences. Next, the site is prepared by clearing and levelling the area.


For decks, footings are installed to provide a stable foundation, while pergolas may require posts to be securely anchored. The framework is then constructed using durable materials to ensure strength and longevity.


Once the structural elements are complete, finishing touches like decking boards, pergola roofing or decorative elements are added.


Finally, the structure is inspected for stability and quality.
