From the Latin for ‘solid ground’, terra firma was an expression used by mariners to describe their nostalgic
yearning for land and a solid foothold. A life at sea is subject vast ocean currents, shifting tides, and
treacherous winds; returning to port, safe harbour provides a contrasting feeling of stability and permanence.
The inhabitants of this home are sailors, their boat sits at anchor just a few meters from their front door, and
though discrete in their instructions, Luigi Rosselli understood there was a subconscious desire for their home
to satisfy a yearning for solid ground, terra firma in the architecture.
Thirty-five years previously, Luigi had a similar experience with the house he built at Cottage Point on the
Hawkesbury River for Andrew and Shelley Farris, as modern day mariners, travelling the world with [the band]
INXS, all they desired was to introduce a sense of permanence to their existence, a place to rest. Somewhat
ironically, the resulting design for that home resembled the prow of a ship excavated from the riverbank.
With this new home, it is not excavated from, rather perched upon a sandstone outcrop overlooking one of
the many sheltered bays scattered throughout the tidal estuary of Sydney Harbour, and it is anchored to the
ground by a robust rammed earth base with a warm sandstone colouring. The two levels above the rammed
earth level are of a brickwork construction using bricks retained from the demolition of the cottage that
originally occupied the site. Privacy, and shading from the sun, are ensured by the use of recycled terracotta
roof tiles assembled in geometric patterns.'
In its four primary construction materials (rammed earth, and recycled brick, terracotta tiles, and reclaimed
sandstone) the house is the embodiment of Domus Terrae, an earthly abode. Unsurprisingly, such natural
materials, particularly those that have been reclaimed from the same site and repurposed, hold the lowest
embodied energy ratings of any materials available to the construction industry. Where concrete was required
in the construction, Boral Concrete’s Envisia product was used, which represents a fifty-percent reduction in
the emissions produced to make a standard concrete product. To cap off the house, a vast array of solar
panels adorns the roof.
Luigi Rosselli Architects enjoy working with a counterpoint technique in their designs; the solidity of the
materials is contrasted by the fluidity of the forms. Employing a ‘J’ shaped plan, with a swimming pool and
terrace embedded into the scoop of its hollow side, the house enjoys a cruiser-like elevated deck, and on the
upper level there is a ‘captain’s bridge’ master suite, complete with funnel and flagpole mast.
The human condition is one that is full of contradictions; a mariner may long for terra firma, but once back on
dry land they are drawn again by the siren call of the sea. This house is an expression of that contradiction.
