After spending about $247K on land, Matt Goodman saved on square footage and splurged on glazing to build a minimalist getaway on stilts that feels like it’s floating.

Matt Goodman had been keeping an eye out for vacant blocks along the Great Ocean Road in Victoria, Australia, for years.

The architect and his wife, Corrie, hail from Wollongong on Australia’s east coast, although they’re based in Melbourne and they often holidayed in the small nearby towns of Separation Creek and Wye River, drawn to their simple lifestyle and similarity to the coastline where they grew up. Building their own beach house in the region was a long-held dream.

In the Australian town of Separation Creek, architect Matt Goodman built a compact beach house for about $270,000 USD. The cabin hovers over the site on stilts, giving it a floating effect.

Such was their connection to the locale that in December 2015, when a wildfire tore through the area, Matt felt compelled to step up. He put word out through local businesses, offering to help residents who had lost their homes rebuild. "It was around the same time that I started my office and I didn’t have a lot of work—and then instantly I had three pro bono jobs," he recalls. "I was busy, but still not making much money."

The custom kitchen counter and dining table set the couple back $5,600 ($3,350 USD), but Matt says it’s now the hub of the home. They installed the wall shelf after moving in at an additional cost of $2,600 ($1,550 USD). It had initially been scrapped to save money, but they quickly realized the extra storage it offered was essential after all.

The silver lining was that the pro bono work gave Matt valuable insight into the landscape. When vacant blocks popped up for sale, "I was able to weed out whether a site was good, or too difficult, or too expensive," he says. "I had knowledge that I could put into our own build, so that we could try to do it for a song."

In 2018 they secured a "perfect" site on a hill overlooking the ocean, but their budget for the build was just $400,000 ($250,000 USD). "We knew the house needed to be compact and simple and cost-effective," Matt says, "but we also wanted it to be a beautiful space where the experience of being down there, surrounded by nature, was really intense."

The cabin’s corrugated iron cladding (Colorbond steel in Windspray) riffs on the quintessential Aussie beach shack’s fiber cement sheeting, but is far more fireproof. When not in use, the cabin can be completely closed off with a sliding gate.

Matt drew inspiration from the area’s ’50s and ’60s beach shacks: small, humble dwellings made with fiber cement sheeting. "They’re often just rectangular footprints, so they’re fairly easy to build, and they’re on stilts, so they’re dealing with the slope in the simplest way," he explains.

Arriving at the cabin is now a joyous ritual. "Every time we push the gates back and see the view, it’s this sense of ‘we’ve arrived,’" Matt says. The cabin’s three walls of corrugated iron sheeting cost $15,000 ($9,000 USD).

Embracing the same spirit of economy and practicality, he designed a contemporary two-bedroom version clad in fire-resistant corrugated iron, hovering over the slope on steel stilts. "We kept the footprint as tiny as possible—it’s just 91 square meters," he says. "The bedrooms are tiny and the ceiling heights aren’t huge, but we did things like using full-height doors and full-height tiles to make the space feel more generous."

That set the stage for the home’s star detail: a wall of glass that doesn’t so much frame the view as immerse you in it. With glazing for the project racking up $37,000 ($22,000 USD), it was the only true splurge, says Matt.

"Where we let loose was on the window," Matt says. "It’s an aluminum window frame, which is bushfire compliant and easy to install, but the way that we detailed it was about hiding the frame so that the eye is drawn into the space."

The couple’s strategy was to save with cost-effective materials such as laminate joinery and fiber cement sheeting, and to spend on a few key details, like the window. Even so, they ended up stripping out many "extras." For instance, they had hoped to wrap the bathroom in bluestone, but they swapped the material for plain porcelain tiles to cut costs; a hidden roller blind for the front window was also scrapped. "By the time we were halfway through construction, we were so broke that every decision was cost-driven," Matt admits. "There’s a handful of power points and downlights that we deleted to save money that we now wish we had."

In lieu of a TV, the Hay modular sofa faces the view, inviting quiet contemplation. Sliding glass doors open to the covered deck, which has a narrow opening in the roof, allows more light into the small space.

After renting several holiday houses in the area, Matt knew a fireplace was a must in this cool coastal region. The Stuv 6 freestanding fireplace from Oblica subtly delineates the dining and living areas.

Matt also did the internal painting himself after baulking at a $15,000 ($9,000 USD) quote, but he says in hindsight, he’d fork out for a professional job. "Painting raw plasterboard is terrible, and we had just three days to get it done before the joinery went in," he says. "We were basically camping on-site—and our daughter, who was one at the time, had chickenpox, so it was the biggest disaster weekend!"

Laminate joinery in the kitchen was one way Matt was able to save costs. "It’s a low-spec material, but we treated it really carefully to make sure it was all quite refined," he says. The range hood from Whispair doubles as a soft light at night.

While their carpenter sourced the blackbutt timber for the combined island bench and dining table at the beginning of the project—a blessing given costs skyrocketed during the pandemic—Matt says the custom piece still felt like a splurge at $5,600 ($3,350 USD). It paid off: the couple and their two young daughters Eadie, three, and Daisy, six months, now spend much of their time together there.

"Looking back, if we had done it any other way, or changed to a cheaper material, the project would’ve been worse off because of it," Matt says.

The bathroom is utilitarian, with simple matte white porcelain tiles and bluestone flooring. The tiling throughout, including the bluestone floor in the kitchen and deck, cost $6,000 ($3,500 USD).

Sisal carpet in the two bedrooms adds natural texture. The Anton aluminum wall light is from Volker Haug Studio, and the bed is a floating blackbutt timber frame from Create Estate.

It was a valuable lesson learned for future client projects, too. "Doing a few things well is really important to the office now," Matt says. "If everything feels cheap, the whole house will feel cheap—but if the things that you actually touch feel really refined then the whole house will feel refined, even if a lot of it was done on a budget."

The family enjoy watching black cockatoos and other wildlife like wallabies, kangaroos, dolphins, and seals from their sofa.

Despite the concessions, Matt says that spending weekends in their new beach shack is "brilliant."

"You feel like you’re floating, surrounded by the trees and the birds," he says. "There’s no TV in the house, so we have music on, and you can switch off and focus on the black cockatoos that have landed in the tree, or listen to the hum of the ocean. Being surrounded by nature, hearing it...it’s so beautiful it makes you want to get out into it."
