Ep 186: The Rules of Modernism

Every rule was made to be broken, except in architecture, where even the act of breaking rules seems to come with its own set of rules. Modernism promised liberation from the past, but it quickly wrote its own commandments into the story—flat roofs, open plans, white walls, and exposed structure became the expected vocabulary. A movement that arrived as rebellion soon carried the weight of convention, and those conventions still shape how we design and judge buildings today. This week, Andrew and I are taking a closer look at the commandments of Modernism—where they came from, why they matter, and what they mean for the way we practice now. Welcome to Episode 186: The Rules of Modernism.  [Note: If you are reading this via email, click here to access the on-site audio player]  If you are interested in seeing just a few of the houses I mentioned on the podcast, you can see them listed on the Realtor.com (here and here are just a few of them) The Roots of Modernism jump to 6:30 Modern architecture did not emerge in a vacuum. It was a response to seismic shifts in society, technology, and culture that took place in the late nineteenth and early twentieth centuries. Industrialization had transformed the way people lived, cities were expanding at unprecedented rates, and new materials like steel, reinforced concrete, and large sheets of plate glass were suddenly available to architects. These inventions were not simply practical tools, they were symbols of a new age. Architects began to ask why they should keep designing buildings that looked like medieval castles or classical temples when the world around them had become faster, lighter, and more efficient. The very idea of progress seemed incompatible with copying the past, and so Modernism positioned itself as the architecture of a new century - an architecture that would represent industry, rationality, and optimism for the future. This rejection of the past was more than an aesthetic preference, it was a manifesto. Ornament was not just unnecessary, it was cast as dishonest and wasteful. Historical references were treated as evidence of cultural stagnation. In their place, Modernists put forward ideas of functional clarity, open planning, and structural honesty. The promise was bold: architecture would no longer serve as a backdrop for tradition, it would become a tool for shaping a better society. Housing would be healthier, cities would be more efficient, and design would finally align with the realities of modern life. It was not only about how buildings looked, but about how they could transform the way people lived … and that is why the roots of Modernism matter to this conversation. The movement began as a radical break from the architectural traditions that came before it, yet it also established a new set of values that quickly hardened into conventions of their own. Before we can explore the “rules” of Modern design, we need to understand the cultural and historical conditions that gave rise to them. Only then can we appreciate the irony that a movement born from revolution became one of the most codified design languages of the twentieth century. By the time Modernism had established itself internationally, the movement that began as rebellion had already created its own set of unwritten rules. Architects may not have published them in a single manifesto, but they were understood all the same. You could look at a building and know whether it was ‘Modern’ or not, based on a handful of essential qualities. These rules were never carved into stone, yet they became the code that defined the movement for decades. To understand Modern design, and to really grasp how it operates, we need to lay out those unspoken commandments - the ideas that quietly dictate what belongs inside the Modernist tradition and what falls outside of it.
