Installing a Deck - Framing and Decking
A complete guide to building a ground-level or raised timber deck: from drawing a scaled plan and getting council approval, through concrete footings, structural framing, and laying composite or hardwood decking boards. Includes handrail installation.
Design, Engineer, and Get a Permit
Draw a scaled plan showing footings, beam spans, joist spacing, and ledger attachment. Submit to your local council or building department for approval. Many jurisdictions require a permit for any deck over 600 mm off the ground.
Set Out and Dig Footings
Use batter boards and string lines to set out the deck footprint with precision. Mark footing locations and dig to below the frost line (or per your local code). Footing diameter is specified by your engineer or span tables.
Pour Concrete Footings
Mix or order concrete and pour into the footing holes, inserting a galvanised post anchor while wet. Allow to cure 48 hours minimum before loading.
Install Posts and Beams
Stand posts in the anchors, brace them plumb, then install beams on post caps. Accurate plumbing now makes everything else easier — a post 5 mm out of plumb becomes visible error in the finished deck.
Install Rim Joists and Joist Hangers
Attach the outer rim joists to the beam ends to form the deck's perimeter box, then install interior joists at 400–450 mm centres using galvanised joist hangers.
Lay Decking Boards
Starting from the house side or most visible edge, install decking boards perpendicular to the joists. Use hidden clip fasteners or face screws with consistent spacing. Snap a chalk line and trim the overhang for a clean edge.
Install Stairs and Handrail
Calculate stringer rise and run within code limits, cut the stringers, and install treads. Build and install posts and rails ensuring handrail height meets code (typically 900–1000 mm).
