Competition - OUTSIDER - Rammed Earth House 2021

 

Explanatory Note

The proposal is based on several decisions that determine: the functional disposition of the uses within the maximum surface established in the bases, the disposition of the structural elements, the overall shape of the building and its orientation, and the location on the ground; as well as the requirement to use rammed earth as a structural element.

The functional arrangement is organized along a circulatory axis with an east-west orientation. From the entrance it articulates the living area and the dining area, both facing south, the cooking area with openings to the north, and ends in the sleeping area facing south and the bathroom with opening to the north.

Practically in the center of the space we place a “Russian stove” to complement the caloric inputs supplied by the solar collectors and the direct gains through the openings facing south.

The building has a rectangular floor plan of 7.50 x 4.00 meters which includes the required functional uses and the perimeter wall of rammed earth. The gabled roof with an inclination of 45º, similar to the latitude corresponding to Dobrava, allows us to integrate the solar panels that produce hot water into the south-facing roof.

The structural wall is on the inside of the building, isolated from the outside in order to take advantage of the conditions of the rammed earth to accumulate the heat from the hot water that circulates through the conduits integrated into the ground, the direct solar contributions and the complementary contributions of the Russian stove.

On a continuous perimeter footing of lightly reinforced concrete we raise the 24 cm thick perimeter wall of rammed earth stabilized with binder where we will support the wooden trusses, all this is surrounded by the envelope formed by wood-insulating-wood sandwich panels and finished in chilla wood. The exterior carpentry will be made of wood and double or triple glazing.

We chose the location of the building, within the area indicated on the bases, in the south end free of trees in order to take advantage of the natural sunlight.
