South Coast Beach House || An Intergenerational Retreat Built to Weather the Coast
Every multigenerational holiday eventually comes down to the same negotiation, quiet versus company, and this South Coast house settles it by floor: private rooms tucked low, shared living lifted into salt-toughened brick and copper above.
Sited on flat land at the edge of a lagoon, a short walk from a surf beach, the house faces north toward wetlands, lime green pastures and the distant ridge of the Great Dividing Range. Designed by Casey Brown Architecture for extended family holidays, the home's plan separates the rhythms of a multigenerational stay before anyone has to ask for space, without sacrificing the panorama that drew the family to the site in the first place.
At dusk, the recessed garage and curved white brick volume present a composed, private face to the street.
From the street, a recessed garage and a curved brick volume present a composed, private face, the first sign of a central spine that runs the length of the ground floor. Inside, the spine rises and falls in height, punctuated by light shafts that draw daylight down past a sequence of bedrooms toward a private master suite and a northern garden terrace beneath a deep cantilevered balcony. A media room curves outward from this spine, its rounded form meeting the front door in a single gesture that softens what is otherwise a fairly disciplined plan, and offers the family a second gathering point once the bedrooms have done their job of giving everyone a door to close.
A cobalt blue mudroom, fitted with a curved bench and pegs for sun hats, marks the transition from coastal exterior to the timber-lined stair leading to the private bedroom level.
The media room's curved brick walls wrap a custom yellow sofa, its rounded form softening the geometry that defines the home's street-facing curve.
A parallel stair leads up to a different register entirely. One open living, dining and kitchen space spans the upper floor, its floating timber ceiling curving north to chase the sun and the view. Two decks project from the room, and a full configuration of opening doors erases the line between inside and out. Above it all, a deep cantilevered roof shelters the glazed northern facade, supported on steel columns so slender they nearly disappear, leaving a band of glazing that wraps the upper level in light and keeps the wetlands and mountains within constant view.
The central spine corridor, its concrete ceiling curving overhead like a wave, links private bedrooms to a striped lounge and the home's hidden red bar.
The material palette is doing more work than it lets on. White brick, rustic outside and more refined within, wraps a concrete structure left exposed throughout, a pairing chosen for its ability to shrug off salt air rather than for its looks alone. The roof, clad in copper, shifts angle gradually from front to rear, while brass doors, windows and railings stand in for materials that would corrode within a season this close to the surf. Stone floors run throughout, heated electrically and powered by a solar array hidden behind the street-facing roofline, with batteries stored in the garage. Combined with double glazing and generous roof overhangs, the house manages its own microclimate without asking its occupants to think about it, sustainable luxury that never announces itself as such.
Beneath a curved timber ceiling that lifts toward the view, the open living, dining and kitchen space draws the lagoon, pastures and mountains into the heart of family life.
A freestanding fireplace anchors the upstairs living area, its dark steel flue rising against brick the colour of the surrounding dunes.
None of this reads as sacrifice. Concrete, brick, brass, copper and tallowwood were shaped by hand, by craftsmen given the kind of time a one-off family house allows, and the result feels less engineered than earned. The privacy downstairs and the gathering space above follow directly from the site, shaped by what the land and climate demanded of a house built to host the same family for decades of holidays to come.
On a lagoon's edge where salt and sun test every material, this house gives a family the rarer gift: room enough to be apart, and reason enough to come back together.
Clad in copper and lifted on slender steel columns, the sweeping roofline appears to hover above the white brick base as evening light catches its underside.
