GJ House by Estudio GMARQ
GJ House anchors a double lot in Hudson, Argentina, as a clear study in minimalist residential architecture by Estudio GMARQ. Conceived as a modern family house, it balances privacy toward the street with a long, glazed relationship to the garden. Inside, concrete, white volumes and warm wood make everyday routines feel composed without losing ease.
From the street, a pale prism rests calmly on a concrete base while narrow openings keep daily life discreet. At the garden side, full-height glass pulls light deep inside and frames the green lawn as part of the interior.
This is a house shaped for a young family in a gated community on Buenos Aires’ outskirts, where modern architecture meets a direct connection with nature. Estudio GMARQ arranges the volumes as a white upper rectangle atop an exposed concrete ground level, using a restrained palette to organize public rooms below and private rooms above. Materials and light do most of the work, steering the experience from closed frontage to open garden edge.
Concrete Base And Prism
The composition starts with that concrete plinth on the ground floor and the large white rectangular prism above it. Toward the street, few openings keep the façade quiet and protect the family from view. The result is a pure, almost abstract volume that sets a clear figure against the suburban context. To the rear, the structure changes character as broad glass panels slide past the concrete and invite the garden into daily routines.
Living Rooms To The Garden
On the ground level, the plan gathers living room, kitchen, dining room, playroom and services around that long garden edge. A closed barbecue room extends toward the lawn, turning weekends and gatherings into an easy indoor-outdoor sequence. Floor-to-ceiling windows define most of this level, bringing natural light across the concrete floor and softening the boundary between terrace and interior rooms. Large volumes stay simple so the view, not decoration, carries the scene.
Wood, Neutral Tones And Light
Inside, a sculptural stair with floating wood treads connects both floors as a warm counterpoint to the structural concrete. A wood-clad volume separates dining from kitchen, while an exposed concrete wall on the opposite side visually ties the room back to the exterior shell. Neutral colors set a calm backdrop; wood adds warmth and texture, and the surrounding greenery becomes the third key hue. This restrained palette keeps focus on proportion, daylight and the changing pattern of shadows.
Quiet Bedrooms And Skylit Hall
The upper floor holds three bedrooms and a playroom, organized as the most intimate zone of the house. Toward the street, walls remain mostly closed to maintain privacy, while the rear elevation opens toward the garden and planted roofs. Along the corridor, a run of skylights casts shifting light into the interior and washes the walls with moving shadows during the day. Black aluminum sliding brise soleils shade the façade and allow the family to tune glare, views and privacy with the seasons.
In the playroom, windows look toward two green roofs, one above the street side and one above the garden side. These planted surfaces extend the domestic landscape upward and round out the project’s quiet presence on its double lot.
By evening, the white prism glows softly above the concrete base as interior light washes the deep window reveals. GJ House reads as a simple form from outside, yet inside, careful use of concrete, wood and daylight shapes a daily setting that stays clear and calm.
