Overview
Decking Built to Structural Standard
A deck is a structure, not just a surface — correct framing, post footings and fixings matter as much as the decking boards themselves. We build every deck to structural standard, whether it's a small platform or a large elevated entertaining area.
Timber choice has the biggest impact on both cost and longevity — from standard treated pine through to premium hardwood, each with different maintenance needs and price points.
A smaller deck starts from around $2,200+ cost of works at our budget rate for 10m², scaling up for larger areas, glass balustrade or under-deck drainage.
Ground-level decks still need adequate subfloor ventilation and clearance beneath the boards — skipping this to save a little height is a common shortcut that leads to premature timber rot, particularly in Perth's damper winter months.
What's typically included
Engineered framing and post footings
Decking boards in your chosen timber
Fixings and structural hardware
Stairs and balustrade where required
