Luxury Penthouse Living with Soaring 3-Metre Ceilings

Occupying a coveted penthouse position at St Clair, apartment 812 is a near-new residence of genuine quality, completed in April 2026, in one of the Sunshine Coast's most sought-after waterfront precincts. Framed by sweeping views across the lake, parkland and hinterland, it delivers natural beauty in the morning and spectacular sunsets in the evening, all from the privacy of your own home.
The design is considered throughout. An expansive open-plan layout is elevated by soaring three-metre ceilings, abundant natural light and a seamless connection between indoor and outdoor living. Floor-to-ceiling glazing draws in the outlook, while the oversized covered balcony is made for morning coffee, long lunches or evening drinks as the sky changes color.
At the heart of the home, the designer kitchen balances refined aesthetics with everyday function. A coastal-inspired palette is paired with premium stone benchtops, an induction cooktop, plumbed refrigerator space and generous custom cabinetry, equally suited to entertaining or relaxed family living.
The main bedroom offers a genuine retreat, with a walk-in robe and a beautifully appointed ensuite. Two additional bedrooms each include built-in wardrobes and are serviced by a well-finished main bathroom, where quality materials and elegant detailing carry the home's standard throughout.
Comfort has been designed in, not added on: zoned ducted air conditioning, ceiling fans throughout, a European laundry, secure intercom entry and premium finishes in every space.
