Step-by-Step Guide to Building Your Deck

Planning Your Deck

Start with a simple sketch of your desired design. Assess your garden's size and shape, ensuring your plan complements existing space. Consider lighting placement and any necessary permits.

Preparing the Ground

Clean and level the area where the deck will be placed. This ensures a stable foundation. Lay down a breathable membrane if necessary, then use OSB boards for added stability.

Installing the Frame

Position your tanalised timber framing. Begin by creating a perimeter and then lay internal joists for support. Ensure framing is square and secure using galvanised fittings.

Laying the Decking

Fasten your decking boards to the frame using appropriate screws. Leave a small gap between boards to account for natural wood expansion and contraction.

Cladding and Finishing
