Full details for the property SP0033.

Spain, ecologically designed property in Garraf, Barcelona.

An exceptionally well designed property with key principles of: 1/High thermal inertia and insulation , 2/ High degree of productive self-sufficiency with renewable energies that satisfy the demands of the house (electricity, hot/cold water), 3/ High degree of collection, re-use of greywater and management of raw sewage. The qualitative jump is high since it contemplates all the aspects of a construction that follows the -CO2,+H2O concept.

The materials used comply with high values of thermal inertia and insulation, with triple glass windows and two air chambers, insulation through cork plates, 60cm walls made of thermal clay (ladrillo de adobe and rammed earth), wood structure (KLH), green covering with soil layers thicker than 20cm., partial burial of the building with a northern orientation, total water treatment, solar capture using plates on the covering oriented southwards, major openings of the main spaces oriented southwards, carpentry with certified wood, thermal inertia of floors retaining solar energy, radiant walls heating, and sanitary hot water and heating/refrigeration using geothermal wells. It is an integral project whose objective is low CO2, high H2O by obtaining the maximum performance of the site.


The project is focused so that the user of the home becomes a producer and not only a consumer. The smallest nucleus of social organization, the family, lives in a house, administrates and produces their necessities to guarantee their comfort being sufficient (conscious of the expenses) and self-sufficient, and, at the same time recovering in the medium or long-term the initial investment.

The main point of the project is defined by the concept of -CO2+ H2O.

The project deals with the experience of living beyond the mere action of occupying space, a house. It is an integral project, applicable to any part of the world, in different degrees and immersed in different social,environmental and economic realities. Under this project the designer's vision is more pluridisciplinar than that of a traditional architect, dealing with other objectives on the blank paper beyond those imposed by aesthetic fashion or rotund projects of recognized architects that work in our cities and landscapes.

The starting point is necessity, and this necessity has 3 perspectives; the satisfaction of an organism inside the body, (the house in itself), the elements outside the body (energies), the obvious waste of the organism (environmental and water management). These three necessities dictate the first drafts of the project, which begins with its design and correct integration in the landscape and the context, as well as its sensitive and aesthetic intentions.

The keystone of the project is the correct management and interpretation of the site, its surroundings and its future users to obtain the maximum environmental efficiency (-CO2, +H2O). The user can become a small producer (of energies, nutrients, etc..), and at the same time a consumer, and even participate in the definition of the landscape of his site, immersed in a broader vision of urbanism and the neighboring houses, identifying community as a whole.

The imperative necessity of -CO2 (LESS CARBON DIOXIDE) is achieved through these following points; maximum inertia and insulation of the materials of the envelope and the closing, self-production and maximum efficiency of the site focusing on the demand for clean and renewable energies (geothermal, biogas and solar panels) that satisfy the equivalent consumption of the users, or sell the energy to the system.

The other essential premise, +H2O, (MORE WATER), is achieved by being present during the whole life cycle of water; capture (pluvial), use, reuse (greywater and raw sewage), nutrients (root systems), and evacuation. As for the aesthetic perspective, the effort is focused on the maximum integration in the landscape by way of immersion in the topography of the terrain, and the consideration of the land as a good thermal inertia and isolation element for the house as well as compositive (for example, green roof).
