"The more formal seating area with the fireplace is two steps lower than the original floor, yet the ceiling is at the same level," says McNamara. "The extra height enhances the sense of space and defines the lounge within the open-plan living area."
The architect was also able to create a separate media room, which appears as a smaller black box within the large black box that is the house.
"This freestanding element is seen as a separate element, and consequently is more of a design feature," she says. "For this reason also, it is devoid of decoration. It has acoustic insulation, and eventually will be glazed around the top as well."
Enlarging the house was not only a way to give the owners a bigger living space, but also improved the circulation through the house. There is now enough space for a walkway to one side of the media room, leading to the kitchen and living area.
The kitchen was not significantly altered. But a new concrete tabletop was added to the end of a peninsula to provide a perching spot for the family and friends. A built-in shelving unit creates a division between the dining area and the lounge.
Interior designer Tomi Williams says the owners favoured Mid-century Modern design, with an industrial edge. This helped to determine the furnishings.
The design also needed to work with the architecture. The black box that encloses the media room is clad in Decortech, which resembles a scaled-down version of the exterior cladding.
