Home Efficiency & Technology Special Contest
Traditional constructive elements were used such as the tile roof, walls of stone, ceramics and brick, solid wood beams, and others. Likewise, passive energy solutions, natural resources, and materials were used in proximity to the site. The site, with incomparable views of the city of Barcelona, Montjuic Mountain and the Mediterranean Sea in the background, creates unusual lighting conditions.
The SV House consists of three levels. On the ground floor are the common areas, living room, kitchen and dining room. Other services in a third module which adjusts itself to the limits of the plot. In the basement, there are the services, with independent access. As well as the guest bedroom, the multipurpose room and bathrooms with access to the garden and the garage.
The spaces of the house are open to the outside. On the facade, the walls and the planters cross the boundaries. Through the garden and its elements, the relationship between the interior and the environment is established, a house connected to the exterior without discontinuities, blurring the boundaries.
The unit of the brick and its dimensions studied, determine the size of the spaces and the module of the metal frames of the steel structure, which rest on the brick walls. This metal grid sets the project in an elastic way, according to the desired needs and limits. It is then a flexible systematization that gives an implicit order to the entire project.
Oak: solid oak beams are integrated into the steel profiles by means of lace made in the upper and lower parts of each element. After being cut, they were allowed to dry in the sun for 3 months.
Steel: the steel grid establishes order and its dimensions are adjusted according to the limits of the project according to its functional program.
Brick: the brick walls are used to structure the spaces and receive the steel grid.
A mixture of sand and clays from the Baix Camp and Baix Ebre regions was used to make the brick. Together, they give the mixture a balance of elasticity and hardness. The manufacturing of the pieces is a handcraft process where the raw material is mixed, passed through the crusher and water is added prior to its passage through the pasteur. The clay formed was introduced in specially crafted wooden molds.
The pieces are left to dry for 2 days on the floor and then when they had consistency, the imperfections (grains) were removed with a sting. Afterward, the drying process continued, under open porches. This process can take up to 30 days.
They were stacked and taken to the furnaces where he used crushed olive bones as fuel. They were baked for a week at high temperatures reaching up to 1000 degrees Celsius; An interesting fact is that depending on the exposure of the piece to the flame, more or less reddish colors are obtained.
To form the rigs, the bricks were designed with four molds of different dimensions according to their function. Two of them are in the corners, one to fill and another, the main piece that configures the rig, allowed the desired end. The 1cm thick joints were built with lime mortar, creating a shadow between pieces. The 0.5cm joint was recast. The white color of the board keeps the walls in harmony with the straw color of the bricks.
