The Victorian terrace house is a common typology in Melbourne, Australia. Sited on a long, narrow lot in the Melbourne suburb of South Yarra, this circa 1930s iteration greets the public with a covered, lacework-decorated front porch; a stained glass bay window; and a hallway tucked along the party wall. Topped with a terra-cotta tile roof, the one-story structure's detailing incorporates elements of the Arts & Crafts and Art Nouveau styles, but its diminutive size “lends itself nicely to a contemporary addition/renovation,” says architect Matt Gibson, RAIA, principal of Melbourne-based Matt Gibson A+D.
And that's exactly what Gibson did, reusing most of the existing structure, recycling and salvaging existing materials, and deploying natural and local products wherever possible to bring the house into the 21st century. “The project provides a case study for the revitalizing of inner-urban, small-plot terrace houses on economic budgets and within sustainable means,” he says.
The architect embraced many of the home's period elements, using them to inform his design. He kept the details on the façade and maintained the size and layout of the two bedrooms in the front of the house, but he moved the bathroom from the rear and extended the back to create an open kitchen/living space. The bath now occupies the middle of the house and has a better relationship to a light-facilitating interior courtyard.
Gibson oriented rooms toward the interior and exterior courtyards to encourage natural ventilation and used vents to these outdoor areas to promote airflow under the house. Interior surfaces are finished with natural oils, natural wax, and low-VOC paints to promote clean indoor air. Large sliding doors and a central pivot door create thermal zoning, and extended eave linings provide shelter from the sun. “Passive cooling and breezeways enable supplementary air conditioning to be used only on the very hottest days,” Gibson says.
The home's interior is a contemporary, yet warm mix of salvaged items—lumber, bricks, and mirrors, for example—and natural products, such as stone walls, sisal carpets, tree bark blinds, and bamboo shade screens. “The kitchen bench top was poured on site using materials from the site, concrete tiles were made locally, the floorboards and furniture timber were salvaged from a local factory in Richmond [another Melbourne suburb], brickwork was reused, and the bronzed outdoor mirror became a last-minute design decision to be reused on the rear fence,” he explains.
“I think the recycling notion in this building is a more holistic approach, as opposed to a literal one of items being recycled,” he adds. “It's the recycling behind the scenes that makes the building cost-effective and embodied energy-effective.”
super savings Salvage lumber and other reclaimed building products are worthy choices, but architects shouldn't forget the intrinsic value of reusing a building's existing structure. This house has its share of recycled boards, bricks, glass, and other materials, but it's the less obvious recycling that provides the biggest bang for the buck, says architect Matt Gibson, RAIA.
“Recycling the building's ‘superstructure'—including its envelope and other structural elements—led to an [approximate savings] of $100,000,” he says.
Recycling incidentals, on the other hand, reduced overall costs by roughly $10,000 to $20,000.
