Vaucluse is one of Sydney’s most exclusive and breathtaking suburbs. Perched on the cliffs above Sydney Harbour, with some of the most valuable real estate in the country, decking here is often ambitious — and the results are extraordinary. Here’s what you’ll invest in 2026.
Decking Costs in Vaucluse (2026)
Vaucluse is at the top end of the Sydney decking market. Elevated sites, complex access, and premium finishes all contribute to higher costs — but the results justify every dollar.
| Material | Cost per m² | Notes |
| Premium Hardwood | $600–$800 | Ironbark, Spotted Gum |
| Millboard / Trex Composite | $750–$1,200 | Top-tier brands |
| Custom Timber | $800–$1,500+ | Architect-designed builds |
Vaucluse’s Unique Challenges
- Steep cliff faces — complex engineering and structural requirements
- Harbour exposure — maximum salt air and wind — only the best materials will last
- Access — many properties require specialised equipment and crane lifts
- Scale — Vaucluse decks are often large multi-level structures
Woollahra Council & Heritage
Vaucluse properties fall under Woollahra Council. The area has significant environmental sensitivity given its harbour foreshore location, and most larger decks will require either a CDC or full DA.
