Exploring the sweet spot of urban density—mid-rise buildings, gentle intensification, and housing forms that balance livability with sustainability.
essayEvery city runs on quiet skill: the nurse who steadies a night shift, the teacher who holds a classroom together, the bus mechanic who keeps the morning fleet alive. If these workers cannot afford to live in the city they serve—or reach their jobs quickly on transit—the urban promise frays.
essayOn a Manhattan street, a four-storey building does quiet economic math: a ground-floor shop generating eight times the per-square-foot rent of three floors of apartments above. For the owner, waiting is rational. For the city, the building is a piece of underused land in a housing emergency. Understanding the difference requires treating zoning, rent regulation, and real-estate markets as one spatial regime, not three separate technical problems.
The number arrives like a diagnosis: 2.8 billion people worldwide lack access to adequate housing. That's 40 percent of humanity living in structures that fail basic tests of safety, security, or sanitation. And for the first time since economists began systematically tracking housing affordability, every major market has crossed into unaffordable territory.
essayArt Nouveau taught us that good geometry and human-scale engineering are productivity tools for happiness. This sequel assembles a pragmatic code: what to keep, what to improve, and where the biggest opportunities lie for climate, comfort, mobility, and cost. When the city is run like good software—clear interfaces, reliable defaults, honest metrics—everyone debugs less and enjoys more.
essayArt Nouveau—call it Jugendstil, Secession, Modernisme, Liberty—was never just ornament. It was a coordinated urban technology for living well in dense neighborhoods: daylight engineered through bay windows, structural walls thick enough to buffer heat and noise, floor plans that cross-ventilate, stoops calibrated for convivial streets.
essayThe sustainable city doesn't need to choose between endless suburbs and glass towers. It needs mid-rise: five to eight storeys of mixed-use, walkable blocks. Three ambitious cities show how.
How cities are tearing down urban highways to reconnect neighborhoods, restore ecological corridors, and reimagine what these corridors can become.
The evolving relationship between cities and water—from flood control to drought resilience, from buried streams to daylit rivers.
