One Column House In Río Negro Province, Argentina


The One Colum House represents the result of a successful refurbishment and extension process that was carried out by NE-AR for a modern summerhouse in Río Negro Province, Argentina. Featuring 4,999 square feet of space, the residence impresses with a modern, spacious design that emphasizes panoramic views and comfort.

The new extension separates the social and private living spaces, and it highlights the differences between the old and the new. The existing abode incorporates two large bedrooms as well as a main bathroom at the ground level. The public spaces are organized linearly and are included in the new extension. We are talking about the open kitchen, the lounging area and a dining space, all of which are linked to a wide-open terrace that faces the lake shore.

The main material used for the extension is reinforced concrete. The design comprises a planar roof that is supported by four inverted beams, all of which converge into a single load bearing vertical element – a column.

From the architect:

NE-AR has completed an extension and refurbishment for an existing summer house on the shores of a Patagonian lake in the South of Argentina: the One Column House.

The existing summer house was lacking of optimum spatial and functional distribution conditions that could fulfil the needs and the ways that the house was used and experienced: the house was sitting far away from the lake shore neglecting the most privileged views towards the lake and its landscape, while at the same time both neighbour houses at the sides block the vistas towards the lake since their footprints were settled closer to the lake shore. Besides, the interior spaces were characterized by a deep dark dinning/ living area with limited relation to the outside.

NE—AR decided to incorporate a detached volume as an extension to the existing house located closer to the lake shore and oriented towards the best landscape vistas, creating an internal patio between the existing house and the extension volume. Thus the new extension establishes a clear division between the public and private areas, the old and the new. While the existing house will host two large bedrooms and the main bathroom in the ground floor, all public areas will be linearly organized within the extension volume: open kitchen, dining place and the lounge area; all these spaces will share a wide open wooden terrace deck facing the lake shore.

The extension structure is mainly built in reinforced concrete: a planar roof runs widely from one neighbour boundary line to the other and is strengthened by four inverted beams that converge in the only load bearing vertical element of the house. This column is formed by a pair of concrete shear walls described by ruled surfaces.

One Column House researches upon the multiple performances a column could achieve beyond its structural capacity. Firstly, it is an element that marks a central place by integrating in itself a fireplace, while articulating the program by organizing the different functional spaces around it and orienting site-specific vistas. At the same time, it stores the fireplace logs and works as an infrastructural device where the rain water pipes are embedded within the twisted shear walls while opening up the concrete roof enabling natural zenith light to come through.
