Front elevation of the Phototropic House, a Boulder custom home designed by AsOne Architecture where roof forms, windows, and outdoor spaces are organized around the movement of sunlight.

PHOTOTROPIC

A home built by phototropism, where movement, structure, and view follow the sun.

Dynamic roofs and purposefully placed windows organize this home around the sun’s path, aligning space, structure, and daily life with light.

Light-filled living room of the Phototropic House featuring exposed timber beams, expansive glazing, and interior spaces oriented toward natural daylight and garden views.

QUIET PHENOMENA

natural forces that shaped this project

Quiet Phenomena icon celebrating natural topography and landforms as inspiration for architecture that responds to terrain instead of resisting it.
Quiet Phenomena icon inspired by natural exoskeletons, influencing expressive structural systems that protect while revealing architectural form.
Quiet Phenomena icon inspired by exposure to sun, wind, and weather, guiding architectural responses to climate, orientation, and seasonal change.
Quiet Phenomena icon exploring the horizon as inspiration for long views, proportion, and the relationship between architecture and landscape.
Quiet Phenomena icon inspired by branching river systems, informing circulation, interconnected spaces, and flexible residential architecture.

Rebuilt on the framework of the original house, the new design follows the behavior of phototropism — the way plants bend and grow toward light. Open kitchen, living, and dining spaces share illumination from multiple directions, while exposed beams and sloping ceilings stretch upward like branches reaching the sun. A south-facing deck rotates west to capture mountain views, with the existing tree softening summer glare. The breakfast nook cantilevers outward on a V-shaped steel column, projecting into the light like a new limb extending from the canopy. Inside, solar-evocative fixtures and an all-white bathroom amplify and reflect daylight, extending the home’s orientation to the sun deep into its daily life.

Covered outdoor dining terrace oriented toward the sun, extending the home's daylight-filled living spaces into the landscape.
