The single-fronted Edwardian home, renovated by Clare Cousins Architects, was extended using angled steel baffle-lined walls.
The front garden is dotted with circular corten steel planters containing herbs and vegetables, including artichokes and nasturtiums. Rosemary, mint and sage sprout around the pebbled ground.
The north-facing rear garden includes a South African silk floss tree and various species of cacti frame the antique-finished bluestone pavers.
However, much of the cost of a garden is often in the unseen elements.
“Preparing the soil, drainage and replacing fences can run up the bill,” says Broad, who sees investing in a garden as a lifestyle choice, rather than for a quick monetary reward.
“Our clients engage us for the pleasure of being surrounded by a beautifully crafted garden for the long term,” he says.
For those mindful of the bottom line, Broad suggests focusing on the garden itself rather than big-ticket items, such as outdoor kitchens.
“Do you need a second kitchen when there’s already a great kitchen a few steps inside?” he asks.
Mel Ogden is known for her highly individual gardens, which often include large granite boulders and reflective translucent screen walls.
For an arts and crafts-style house, Odgen worked closely with architects and interior designers.
While the original, old-fashioned front garden, complete with rose beds, suggested a period charm, the rear addition focused on a contemporary design – with landmark boulders and an acidic retro reflective garden wall and a pergola.
“This garden was about 10 per cent of the build price, but it added significantly more, given the outdoor space is used as another room,” says Ogden. “The plants themselves are usually the less expensive part of the program, unless you want an instant garden with mature trees,” she says.
Owner and landscape designer Richard Haigh, of Parterre, in Woollahra, Sydney, says spending on a garden often results in long-term financial benefits.
“If a garden is well designed, you can easily see a 25 per cent increase in what’s achieved on auction day,” says Haigh. “Some people want a house where everything is complete and ready to move in.
“Most people spend 50 per cent of their time outdoors, so it’s worth the investment,” Haigh says.
