A Stunning Millboard Deck Transformation in Castlecrag, Sydney
This recently completed project in Castlecrag on Sydney’s Lower North Shore is one of our most impressive builds to date. Perched above Middle Harbour with sweeping water views, the brief was to transform a tired outdoor space into a premium, low-maintenance entertaining zone — and the result speaks for itself.
We specified Millboard composite decking throughout — a premium, 100% wood-free board that delivers the authentic look of real timber without any of the maintenance. No oiling, no sanding, no warping. Just beautiful, durable decking that performs in Sydney’s coastal conditions year after year.
Project Scope
- Large multi-level entertainment deck — spanning the rear of the home with space for outdoor dining, a BBQ kitchen and lounge area
- Curved pool surround — Millboard boards cut and laid to follow the pool edge, with integrated LED deck lights
- Feature staircase — full-width timber-look steps with LED risers, descending from the upper entertaining deck to the pool level
- Frameless glass balustrades — maximising the Middle Harbour views while keeping the space safe and compliant
- Sandstone wall integration — the deck was built to sit perfectly against the existing sandstone retaining wall
Why Millboard for a Harbour-Side Property?
Millboard Enhanced Grain composite decking is the premium choice for waterfront and coastal properties. Here’s why it was the right call for this Castlecrag project:
- Zero maintenance — no annual oiling or sanding like hardwood timber requires
- Salt and moisture resistant — ideal for harbour-side environments where salt air accelerates timber deterioration
- Slip-resistant surface — P4 rated for wet areas, making it safe around the pool
- 25-year product warranty — genuine long-term peace of mind
- Authentic timber appearance — each board has a unique moulded grain that looks and feels like real hardwood
- Eco-friendly — 100% wood-free, no tropical hardwoods used
For a property like this one in Castlecrag — elevated, exposed to the elements, and used heavily for entertaining — Millboard is simply the right product. The client won’t need to think about the deck again for decades.
LED Deck Lighting — The Finishing Touch
One of the standout features of this project is the integrated LED step and deck lighting. Recessed into the stair risers and along the deck edge, the lights transform the space at night — creating a warm, inviting ambiance while also improving safety on the steps and around the pool area.
LED deck lighting is increasingly popular on premium builds in Sydney’s North Shore suburbs, and it’s something we’re happy to incorporate into any project — new or replacement.
