Clinton Cole is what you might call the thinking person’s architect. While most people looking to build or renovate are understandably focused primarily on budget and aesthetics, the motivations of his clients tend to run to deeper roots.
Take, for example, this house in the Sydney suburb of Manly.
With uninterrupted ocean views in one direction and national park in the other, the temptation for the owners was to do as their neighbours had done and build a multi-storey mansion that directed all attention to the water.
An extraordinary site with almost endless possibilities, it sits on a larger parcel of land owned by the Catholic Church and sold as a longhold lease. When the owners bought the lease, there was a small 1960s cottage on the site that was inadequate for the needs of the family of four. Its position sandwiched between bushland and the surf also meant it is within a wildlife corridor and bushfire risk zone.
The clients, who are originally from Austria, wanted a home that would not only take in the ocean view, but make them and their tween-age daughters feel a part of the natural environment, all with an overlay of luxury.
They were also interested — very interested — in making the house as environmentally sustainable as possible, both in its construction and its ongoing functioning.
So when they discussed the brief with Cole, director of CplusC Architects + Builders, rather than talk about bedrooms and bathrooms or European appliances, they expressed how they wanted to experience spaces.
“They’re outdoorsy — it’s kayaks, bikes, paddle boards, bushwalking,” Cole says. “They talked about, at that first meeting, how they really loved the experience of walking through a shallow creek, the canopy of the trees hovering over the creek, that dappled light and the light reflecting off the water and how beautiful that was. I said: great, there’s your concept.”
The little cottage had to go. In its stead, Cole conceived a three-storey, four-bedroom house with study, a spacious eat-in kitchen packed with integrated storage and multiple living areas, including a rumpus room, of sorts.
“They talked about it more as an art room or entertainment room, but the entertainment was more just listening to music and occasionally watching TV,” says Cole.
“It was really a room for doing craft and art — a very craft-driven, rather than an entertainment-driven, rumpus room.”
A lower ground garage next to the entry and partially dug into the site provides storage for the family EV, as well as e-scooters, e-bikes, surfboards and two storage batteries to make maximum use of the energy generated from the 66 solar panel, 24.5kw system.
“Initially they only had one battery but they were gifting so much power to the grid that he said, ‘now I’m getting two’.
“They don’t pay a power bill,” says Cole. “There’s also a 15,000L rainwater storage underground next to the pool.”
Key to the concept was the indoor and outdoor spaces becoming one, allowing for abundant natural light and optimum but controlled air flow, as well as a family pool that relies on natural processes for filtration.
“It’s a natural pool so there’s no chlorine,” he says. “There’s frogs and fish in the pool.
“The frogs are having the time of their lives, as are the bandicoots — the site is in a bandicoot corridor as well.”
Placing the pool alongside the living areas — pool fencing regulations notwithstanding — was not just about providing somewhere for the clients to swim, and even fish, when the mood takes them.
“This was an opportunity (to create a space) where they described that dappled light and that feeling of walking up against the flow of a creek,” says Cole. “It was just obvious to put a body of water as the outlook (for the house), and have it on the north side.
“Then you get light dancing on the ceilings and refracting through glass at all different times of year.”
That desire to refract light also influenced the decision to install coloured glass in the double height living space, creating dynamic interiors that change with the passing of the sun over the day. It reiterates Cole’s position that how you live in your home day to day is often not about the most obvious view.
“Views are great when you walk into a house when you buy it but as time goes on, it’s less important,” he says. “I think Harry Seidler made me aware of this when he designed his own house. He designed his dining room table so he and his wife sat at the pointy end of the table and all the guests sat around looking out to the view.”
After researching the options, they chose to pour the slab using a low carbon concrete called Envisia, by Boral.
“It has about 30 percent of the embodied carbon of normal concrete and it doesn’t cost any more,” he says. “It also has a higher plasticity and a longer curing time. The higher plasticity is beneficial in terms of its slightly better waterproofing qualities.”
Because his team were also responsible for constructing the house, once the foundations were laid, the rest of the house was built from timber.
“We are a carpentry-based team so our workers have those skills to erect structures of that nature — and you can’t get a lower embodied energy than timber,” he says.
The initial plan was to demolish the old cottage and deal with the materials on site, but after careful consideration, it was decided it was not a feasible option.
“The plan was to crush that little house up, crush up the rock that was on the site and then use that for the walls of the landscaping, retaining walls and the garage wall below,” says Cole. “It turned out that retaining that onsite and getting the crusher to do that was about $50k. The (owners) did consider it but if we brought in crushed material, it was about $5k.
“It was a beautiful idea of doing it onsite but the practicalities of storing it and bringing in this 50 tonne crusher didn’t add up.”
Thanks to its position next to national park, the house was also subject to a Bushfire Attack Level (BAL) of 29. While not the highest rating, it meant that all external timbers had to be fire resistant hardwoods.
Choosing to take a wholly sustainable approach came with a higher price tag but not only were the clients willing to pay, they fully understood why they were doing it. Now retired, one of the owners is a former member of the executive team of a global software company that prides itself on achieving a high level of corporate responsibility and he carried that ethos of ESG into this project.
Cole says the clients were intentionally engaged in every aspect of the design and build process, which resulted in more than 30,000 emails being exchanged over the course of the two-year project to nut out the details.
“It meant there was no room for confusion,” says Cole.
While Cole admits it’s one of the toughest projects he has worked on, he says it has also been the most satisfying, creating opportunities to explore ideas and methods and refine notions about sustainable design and building practices.
“It’s as close as we have ever come to getting everything right, because we were pushed by the client, to be honest,” he says. “We had the time and we were allowed to do the research to get it to this point. Even if it cost more, even if there was a supply issue, we were able to provide the client with an informed choice.”
While the house looks and feels like an extension of the environment as it transitions from bushland to sand and surf, it’s every inch a luxurious environment. Perhaps because of the owner’s tech background, the house has been fully automated, from thumbprint entry and touch free lighting to thermal monitors and sensors to control plant watering. Other aspects are decidedly low tech and old school, like carefully placed louvred windows to manage sea breezes and the built-in thermal mass that naturally regulates heating and cooling. Additional temperature control is via a hydronic system embedded in the slab using heat pump technology.
Cole says, with the right approach, it is possible to create a home that is both sustainable and luxurious.
“There’s not many clients who can put luxury and sustainability together,” he says. “Most people think it’s either/or. The architectural industry itself has historically promoted big expensive houses where sustainability is absolutely unimportant. That’s what they think luxury is — and it’s not luxury.”

The enduring appeal of marble has gone into overdrive as designers explore the beauty of coloured stone to create truly inviting and indulgent interiors.
Like all design movements, the return of marble to interiors started quietly enough with the rise of ‘greige’ as the dominant colour palette. A warm version of grey, for a while there, you could barely step into a well-considered residential space without being confronted with the ubiquitous neutral tone.
However, to be successful, this look depended on texture, layering and patterning to provide truly heartfelt spaces with genuine depth. And so Calacatta and Carrara marble entered the room, literally making itself at home in kitchens, bathrooms, and living room hearths, as well as in a myriad of accessories and furniture from small bowls and coasters to coffee and dining tables.
As greige made way for a return to colour in interiors, in recent years designers have turned their attention to bolder choices, moving on from the classic tones of Calacatta, Carrara, and Pietra marbles to Verde Indio, Spanish Gold, and Calacatta Viola.
Not that there is anything new about marble. First documented for use in construction in 3rd century Greece BCE, with evidence it was also used in ancient Turkey and Rome, it was originally chosen for its strength and beauty, as well as its accessibility, extracted from quarries using hammers and wedges and removed using pulleys, levers, and winches rather than the more difficult process of mining. While extraction methods have improved, especially in recent years, the nature of this popular stone is unchanged.
A metamorphic rock composed mostly of calcite, it is formed when limestone is subjected to heat and pressure. When the calcite in the limestone recrystallises, it forms a rock that is a mass of interlocking crystals, creating what we know as marble.
While many countries, including Australia, have marble deposits, about half the world’s supply is sourced from just four countries—Spain, Italy, India, and China. Strong enough to endure extended use, it is also soft enough to be relatively easy to carve while its natural beauty allows it to be polished and honed, giving it a glow that adds depth—and a sense of luxury—to any space it inhabits.
Australian designers have been quick to embrace the use of marble, offering, as it does, the opportunity to create truly unique interiors. Creative director of Mim Design, Emma Mahlook, says while budget is always a consideration, a greater variety of marble has become easier to source in recent years.
“Coloured stones provide an opportunity to create distinctive and striking spaces,” she says. “As such, we are finding that there is a slight shift to bolder and braver choices of coloured stone than the traditional whites and greys.”
For homeowners interested in creating distinctive, outstanding spaces, it is hard to beat, with each piece different from the other.
“No batch of stone is ever the same, which makes it so unique and such an interesting and visually appealing product with colours, textures, and patterns that are sometimes as complex as intricate works of art,” says Mahlook.
She cites a recent commercial project her studio realised for Enoteca Boccaccio, an exclusive Italian restaurant in the heart of the Melbourne suburb of Balwyn, where she specified a selection of coloured marbles to create an intimate and luxurious dining experience that looks to the past, as well as the future.
“The choices of natural stone in Enoteca Boccaccio, which featured marbles Rosso Levanto and Carrara as well as a granite called Domino, were selected to reflect Italy’s streets and embody genuine durability and commitment to the art of preservation,” says Mahlook. “Rosso Levanto and Carrara are archaic marbles with such strong significance connecting to Italy’s rich heritage.”
Colour and Communications Manager at Dulux, Andrea Lucena-Orr, says the interest in coloured marble in Australian design has its origins in more transient hospitality spaces like bars and restaurants, where design is traditionally riskier.
“Typically, it starts in hospitality and commercial environments,” she says. “You tend to get it in high-end homes because it is expensive, but it’s beautiful.”
“That whole natural palette is a huge phenomenon—people are celebrating those imperfections in patterns and shapes now.”
Because no two slabs are the same, Mahlook says there’s the ability to create truly distinctive, personal spaces for clients seeking genuinely idiosyncratic interiors.
“The movement towards coloured natural stones reflects a broader cultural shift towards individuality, sustainability, and innovation in design and architecture,” she says.
For those falling under its spell, Director of Studio Tate, Alex Hopkins, says marble pairs well with other materials such as timber and looks beautiful indoors, particularly in kitchens and bathrooms. However, she cautions there are some things to consider before specifying it at home.
“To ensure marble remains a timeless choice rather than a fleeting trend, we recommend using it selectively and pairing it with contrasting materials,” she says. “It’s crucial to understand its maintenance demands and consider the overall budget, including installation and upkeep costs.”
While it is susceptible to staining because of its porosity, Hopkins says using marble sparingly, for example, in a powder room vanity, can minimise maintenance.
“Different finishes, like honed surfaces, can also help reduce the appearance of wear,” she says. “Working with experienced designers or specialists ensures the marble chosen fits both the aesthetic and functional needs of your space.”
Professionally applied sealants can also make staining less likely.
For those bold enough to take the plunge, Hopkins says the rewards are great.
“Its diverse colour palette and natural veining offer a unique aesthetic that other materials can’t match,” she says.
