Building bigger is not better

Did you know Australia boasts the larges average home size anywhere in the world? The market is full of oversized, inefficient homes that aren’t sustainable or necessary and we’re sick of it. That’s why we sat down with Imogen from IP Architecture, who’s challenging the ‘bigger is better’ mindset and setting new standards for sustainable living. Imogen’s journey in architecture began with the mud brick house her parents built. "My parents built their own house when I was a baby, and it was a mud brick house with recycled materials. That was really influential on me," she recalled. This early exposure to sustainable building materials and passive solar design principles stayed with her as she pursued her architecture degree and later her career. Today, Imogen's designs continue to reflect her commitment to sustainability. She strongly believes in the principles of passive solar design, which involves working with the natural environment to heat and cool homes efficiently. "For me, the principles of passive solar design are just basic architecture," she explained. "It shouldn't be something that’s celebrated; it should be the norm." I’m sure you know how passionate we are about the Passive House movement, and Imogen shares this enthusiasm. Passive houses take passive solar design a step further, using advanced building physics to create airtight homes that maintain a comfortable indoor climate year-round. Though it might mean more initial embodied carbon due to extra insulation and mechanical systems, the long-term operational energy savings are undeniable. Our conversation then turned to a pressing issue in the Australian building industry—our penchant for oversized homes. It seems like every year they get bigger and bigger, with another guest room, or media room, or kids room. Imogen has successfully made it her mission to show clients that a well-designed, compact home can meet all their needs without the excess. "One of my favourite things about being an architect is making people's briefs work in the most compact building envelope," she explained. She’s developed a process that involves deeply understanding her clients’ lifestyles and future needs. Asking detailed questions helps her clients re-evaluate their actual needs versus their initial desires, leading to more efficient, sustainable design solutions. However, it’s not only client expectations that complicate matters. Real estate market norms and outdated policies are significant barriers. Imogen shared how challenging it can be to convince clients to build for themselves and not for resale value. "People need to realise that a well-designed, comfortable, and sustainable house will be invaluable to someone else too," she stated. Changing the building industry to favour sustainability requires both bottom-up and top-down efforts. As designers and builders, we can lead by example, showcasing projects that highlight the beauty and practicality of sustainable architecture. Meanwhile, we must advocate for policy reform that allows for modern, eco-friendly innovations even within heritage contexts. Imogen is proof that real change is possible, it just requires dedication, creativity, and a willingness to ask the hard questions. So, take this as a challenge, get out there, and push for more sustainable, innovative, and thoughtful solutions in our industry. Together, we can make sustainable and efficient design the standard, not the exception.
