Pirihueico house in Chile is designed by Aalejandro Aravena and completed in 2004.

“So be it the force of self construction, the force of common sense or the force of nature, all these forces need to be translated into form. and what the form is modelling and shaping is not cement, bricks, or wood. It is life itself. Design’s power of synthesis is just an attempt to put the innermost core of architecture the force of life.”  – Alejandro Aravena

To establish an identity to this house, any priori architectural language related to this volcanic site is erased.  

Design philosophy

The requirements of the client included building the house in the color of shadows, creating an equation taking into account various design aspects which affect the planning, design process. The major challenges included procuring the materials to this remote site, developing a new identity for the building. Owing to the extreme weather conditions, less risks were taken to ensure safety.

The language of vernacularism and sustainable building techniques are evident all over the place. This house was developed on the lines of climate-responsive architecture.

Planning and Design

The spaces are arranged in a linear configuration yet allowing more natural light into each of the spaces.

The site being exposed to extreme climatic conditions, the double sloped conventional roof is provided on the second floor in contrast to the first floor which is a dry resistance box to deal with the seismic actions in the ground, moisture, weather. The lower level is sunk into the ground for the same reason. 

Construction

Considering the site context, a double sloped conventional roof suits the site best. But slowly the roof of this house is modified owing to extreme winds, capturing magnificent sceneries and to create visual interest.

The wooden frames on the ground floor support the starting points of the roof.

French doors and windows are used to create a seamless view towards the breath-taking natural setting. These window frames act as arrivals and exits and on the upper level, they function as columns supporting the roof structure.

Materials

The earthy material palette consisted of wood and stones which were obtained from the clearance made on site for the house. The darkness of the object retains the original density of the place and is achieved courtesy of stones used on the facade. These materials also merge the building with surroundings rather than dominating.

The interiors were painted white bringing harmony in the exteriors and interiors.

This building is an ideal example of a rational approach to the requirements.
