About X House

X House is an innovative residential project set on an urban corner lot in Buenos Aires, Argentina. The design responds directly to its immediate context by leaning against the neighboring structure, a move that opens broad views, strengthens natural ventilation, and creates a quieter setting within the city’s busy fabric.

At the center of the house is a reinforced concrete exoskeleton that gives the building its structure and its character. Diagonal supports carry loads down to the ground, freeing the interior from conventional columns and allowing an open-plan layout that moves easily between functional zones.

That structural strategy makes room for generous glazed curtain walls. Glass draws daylight deep into the interior and keeps the house in steady conversation with the surrounding landscape, while the exposed concrete frame brings a raw, tactile surface to the composition. The contrast between solid concrete and transparent glass gives the house its balance of weight and lightness.

The exoskeleton also serves a practical role in a seismically active region like Buenos Aires, where stability matters as much as openness. Its capacity for seismic resistance joins engineering and architecture in a single system, giving the house durability without closing it off from the city.

X House presents shelter as both structure and sequence. Here, engineering is not hidden; it shapes the way light enters, how air moves, and how the rooms relate to the corner site around them.
