Architects Simone Solinas and Gabriel Gallego present their project for 26 bioclimatic social houses in Umbrete. Located in the north area of Umbrete, in a part of the residential surroundings of Seville this project is a result of a search for a prototype of social housing.
The project for the building of 26 Bioclimatic Social Houses in Umbrete aims to define two key concepts at the same time: the standard house and the global image of the intervention, as well as the relation of both with the urban context. Our purpose is to exploit the available surface completely, without leaving any space unused, articulating series of full and empty volumes and establishing a close connection between each other and defining the whole project.
The standard House is repeated always the same, slightly modified only to be adapted to the irregular shape of one side of the plot, generating this way some modifications to the standard model of this social Andalusian houses. The global image is almost not affected by these differences. It allows the formalization of a project where from the outside you just note the different cells by which it is composed, and offers a vision of unity and an image that dialogue with the urban path, living harmoniously with the examples of traditional domestic architecture.
The main planning effort was directed towards a passive energy operating of the buildings, since the construction costs of only 526, 00 Euro/m² and the sale price of 68.355,00 Euro for each house, made impossible the installation of active technology systems. The structure simplicity, and the use of materials easily available on site and well-known by local building workers, have been the central choices; big thermal mass in the foundation, walls and roofs in vaults, allow us to isolate from heat in summer and from cold in winter. The proposed distribution, despite of the unlucky orientation of the plot, allows us to have living rooms and main bedrooms with one side towards the south and the other to the north, as well as taking advantage of a natural cross-ventilation, both fundamental aspects in the climate of southern Spain. Letting the sun come in, taking advantage of the seasonal variation of its angle of incidence, and protecting ourselves with vegetation and typical regional horizontal awnings during the summer, promote a huge quality of the built space.
Starting from the project data and carefully analyzing the context, introducing elements of sustainability, necessary but not sufficient in itself (materials, longevity, energy balance, passive use of environmental, natural light, natural ventilation, orientation, volumes, etc.), we achieve the most advantageous welfare housing, limiting the consumption and waste. The architecture is a great amalgam of elements that must work together (structure, technical installations, economy, passive and active systems, etc.) towards a constructive global act, without forgetting that we have to reach a formal and aesthetical richness too, a fundamental aspect in our work. Promoting and building a sustainable architecture in this century could be a great opportunity for a new revolution in architecture.
