The Shark House is a bold four-storey waterfront residence located in Blackwall on Darkinjung Country, on the NSW Central Coast
Replacing a modest weatherboard cottage, the project is a knockdown rebuild that responds to a highly constrained 460-square-metre site, bounded by the water to the front and a steep rocky reserve to the rear. With limited footprint and strict planning controls, the design adopts a vertical strategy to maximise floor area, views and amenity.
Designed as a home for entertaining, the residence is organised to place living spaces and experiences where they are most impactful. A rooftop infinity pool and entertaining terrace crown the building, freeing up ground-level space while delivering panoramic views across Brisbane Water to the Rip Bridge. This elevated outdoor zone becomes the home’s social heart, complete with an outdoor kitchen and amenities, all accessed via lift.
Materially, the architecture is defined by off-form concrete, natural stone cladding and timber-look detailing, selected for durability in the coastal environment and to visually anchor the building within its rocky setting. Black-framed glazing captures expansive water views while maintaining a restrained, sculptural exterior.
Arrival is marked by a distinctive entry sequence of stepping stones crossing a pond inhabited by tropical fish and baby sharks—an element that gives the house its name. Internally, a floating stair rises through a full-height glass atrium, drawing daylight deep into the home and reinforcing a strong vertical connection between levels.
Inside, the main living level is oriented entirely toward the water, with floor-to-ceiling glazing, refined joinery and a dramatic glass-bottom pool overhead that filters light through the space. The Shark House transforms site constraints into architectural opportunity, delivering a striking yet serene coastal home deeply connected to water, light and place.
Exterior Architecture & Facade Details
The exterior facade of the Shark House is a sculptural response to its rugged coastal environment, designed to be as durable as it is visually striking.
To combat the marine conditions, we utilized a robust material palette that anchors the four-storey residence into the steep rocky reserve.
The facade is a play of heavy, permanent masses—like off-form concrete and natural stone—contrasted against the lightness of expansive glazing and a rooftop pool that seems to disappear into the horizon.
Interior Spaces & Features
The interiors of the Shark House are a sophisticated study in coastal modernism. The design prioritizes a seamless transition between the rugged, rocky landscape of the rear reserve and the expansive waterfront.
By utilizing a vertical design strategy, the interior achieves a sense of monumental scale within a compact footprint, characterized by light-filled voids and a disciplined, sculptural approach to materiality.
Subterranean Shark Pond
The arrival experience is defined by a dramatic entry sequence where geometric concrete stepping stones float over a custom pond. Inhabited by tropical fish and baby sharks, this feature provides an immediate, immersive connection to marine life that establishes the home’s unique identity.
Deeply connected to the tides and the terrain, the Shark House is more than just a residence; it is a living ecosystem designed to celebrate its unique waterfront context.
While the architecture is defined by its bold concrete forms and sophisticated engineering, its true soul lies in the quiet moments—the dappled light filtering through the pool overhead and the gentle movement in the entry pond below.
As the home’s namesake resident settles into his geometric sanctuary, he serves as a living reminder of the project’s core philosophy: a home that doesn’t just overlook the water, but truly belongs to it.
