In architecture, there’s often a tension between ambitious designs and practical execution. Many homeowners fear that great design can lead to costly, unbuildable projects. At Kreis Grennan Architecture, Chris Kreis and Christian Grennan expertly navigate this challenge by marrying architectural vision with deep construction knowledge. Their philosophy is simple: a great design should not only look good on paper but also stand tall in reality—efficiently, sustainably, and beautifully. Here's how they ensure their designs are both inspiring and buildable.
The Design-Build Connection
“For us, understanding the material and its potential is key,” Christian explains. “When you design with the material in mind from the start, you can explore its possibilities while avoiding problems during construction.”
Chris elaborates, “We think of the construction process as early as the concept stage. It's not about limiting creativity; it’s about ensuring every design element works practically. If we don’t consider buildability early, you risk forcing a material onto a design, which often leads to inefficiencies, increased costs, or compromises later.”
This approach reflects their combined expertise as architects and builders, with Christian holding a builder’s license and both partners having hands-on construction experience. “Our practical understanding allows us to foresee challenges and address them before they become costly problems,” says Chris.
The Paperclip Philosophy
When it comes to elegant solutions, simplicity often reigns supreme. Christian uses the humble paperclip as a metaphor for great design. “It’s a bent piece of wire, but it’s incredibly elegant because it works perfectly with the material’s properties. That’s the kind of clarity we aim for in our projects.”
Take their Two Under a Hat project, for instance. The clients needed a dual-occupancy solution but wanted to avoid the “cookie-cutter” look of many duplexes. Kreis Grennan’s solution was a single, cohesive roof structure that fit naturally into the neighbourhood. “The design didn’t scream ‘duplex,’ but it met all the practical needs of the clients and worked seamlessly within the site’s constraints,” says Christian. “It’s not about compromise; it’s about integration.”
Solving Challenges Early
At Kreis Grennan Architecture, potential challenges are tackled head-on during the design process. Christian points out that inexperienced designers often overlook key practicalities, like the dimensions of structural materials or the placement of services. “You might end up with a beautiful design on paper, but if it requires a series of columns in the middle of your living space or a downpipe cutting through your kitchen, the entire idea falls apart.”
Similarly, it’s important to critically assess the client’s needs and come up with the ideal solution. “One of the most expensive mistakes a client can make is building a basement unnecessarily. Basements can be great, but they’re costly and complicated. We often ask clients, ‘Do you really need this space? Could the same functionality be achieved through landscaping or a simpler solution?’ It’s about finding alternatives that meet the brief without inflating the budget.” This approach can save tens of thousands, even hundreds of thousands of dollars over the entire project.
This proactive approach not only saves money but ensures the final design feels intentional and well-executed.
Collaboration: The Secret Ingredient
Collaboration is at the heart of Kreis Grennan’s philosophy. They work closely with builders, tradespeople, and consultants to ensure the design transitions smoothly from concept to construction. “We treat builders as partners,” says Chris. “They bring valuable on-the-ground insights, and by involving them early, we can anticipate and resolve potential issues.”
This collaborative mindset extends to their clients. Kreis Grennan takes the time to deeply understand their needs, habits, and future plans. Christian recalls, “We’re not just designing for now. We consider how the house might evolve with the family over 10, 15, or even 20 years. It’s about creating spaces that adapt to the client’s life.”
Sustainability Through Buildability
Great design also considers long-term sustainability. By understanding materials and their lifecycle, Kreis Grennan creates homes that require minimal maintenance while remaining adaptable for future use. Christian explains, “Natural materials, like timber and face brick, age beautifully with little upkeep. In contrast, rendered finishes often crack and degrade over time, requiring constant repair.”
Their focus on sustainability is also evident in how they design for energy efficiency. For example, integrating Passive House principles ensures that their homes remain comfortable year-round while minimising energy consumption. “We design buildings that are not just functional but also responsible,” says Chris.
From Theory to Reality
The Rod Point Twins project is another example of how Kreis Grennan’s approach delivers both beauty and practicality. Faced with a site that offered stunning water views at the front and lush gardens at the rear, they devised a solution that maximised both aspects. The design featured a split-level layout with sculpted brickwork, creating visual interest while maintaining structural integrity. “We added a bit of love to the façade,” says Christian, “but every decision was grounded in what was achievable and efficient.”
Adding Value Over Time
Beyond the immediate build, Kreis Grennan designs with long-term adaptability and maintenance in mind. “A buildable design is easier to maintain and adapt for future renovations,” says Christian. “We encourage clients to think about durability and flexibility—materials that last, spaces that evolve with their needs, and designs that will retain value over decades.”
“Buildable doesn’t mean boring. It means thoughtful. It’s about making smart decisions upfront so the design not only works today but continues to work for years to come.”
Why Buildability Matters
At Kreis Grennan Architecture, buildability is a philosophy, not a limitation. “When design and construction are considered together, the result is a home that’s not just beautiful but practical, sustainable, and a joy to live in,” says Chris.
Christian sums it up: “Great design doesn’t have to be difficult to build. It just takes the right mindset, a collaborative approach, and a commitment to understanding both the materials and the people who’ll use the space.”
Final Thoughts
For anyone embarking on a new build or renovation, working with architects who prioritise buildability is the key to success. Kreis Grennan’s unique combination of design flair and construction expertise ensures that their clients receive homes that are not only architecturally stunning but also perfectly suited to real-world living.
