A piece of sustainable architecture in Buenos Aires

The system of water basins and the outer shell that encloses Casa Holmberg by Estudio Borrachia, transform the house into a dynamic ecosystem in the heart of the city.

On a plot of 10X17 meters in the Belgrano district of the Argentine capital, Estudio Borrachia builds a three-storey house for a young family of four.

The dry-assembled steel framework structure of the volumes identifies three courtyards on the ground floor: an entrance garden, a pond enclosed between the buildings and a back garden with a swimming pool.

Thanks to a flexible and undivided floor plan, all the rooms in the house overlook the patios through the continuous glazed surfaces that buffer the volume, generating constant cross-ventilation.

But the peculiarity of the project is its casing. In addition to shielding the house from the sun, the vertical pipes that make up the façade are crossed by hot and cold water that draw from the shaded water basin on the ground floor and from the one in the sun on the roof, making it possible to thermally condition the house and transform it into a sort of large radiator.

This integrated thermoregulation system has generated a real oasis in the city, inhabited not only by the family but also by a very rich variety of birds, insects and plants.

The result is a project whose architectural image corresponds to its sustainability.
