cristian nanzer cuts skylights into this 'casa cosmos' for a triangulated view of the stars

"From a single point on the plot, the concrete house establishes its geometry in response to three distant landmarks. To the south, the reserve extends toward Las Gemelas hills. To the northeast rises Mount Uritorco. To the west, El Cajón Dam reflects the sky. This triangulated reading of the landscape gives the project its plan and its spatial logic."

"At the center, a triangular skylight introduces diffuse daylight from above. Its geometry mirrors the plan while functioning as a quiet chronometer. As the sun shifts, light traces the interior surfaces, marking the hours across concrete planes and floor surfaces. Time becomes legible through subtle tonal changes rather than through applied devices."

"Through its interior atmosphere, Cristián Nanzer's Casa Cosmos recalls a hollowed promontory. Three deep galleries carve into the polyhedral volume, lending shaded exterior rooms that extend the interior outward. Each opening expresses a thickness and creates a measured transition between enclosure and horizon."

Casa Cosmos, designed by architect Cristián Nanzer, sits on a sloping site in Córdoba, Argentina's Punilla Valley, overlooking a protected natural reserve. The home's geometry originates from three distant landmarks: Las Gemelas hills to the south, Mount Uritorco to the northeast, and El Cajón Dam to the west. This triangulated landscape reading informs the building's plan and spatial organization. The interior features a triangular matrix distributing rooms centrifugally around a central social space, with kitchen and dining areas forming a continuous domestic field. An en suite bedroom and studio branch outward, defined by thick walls that moderate light, sound, and heat. A central triangular skylight introduces diffuse daylight, functioning as a chronometer where shifting sunlight marks time across concrete surfaces through subtle tonal changes.
