Home╱A Natural House
Hemp, lime and marés, a natural house. This is the name Ideo Arquitectura have baptized this house in the south of the island of Mallorca. They have faced the project under the premise: "think global, act local". Or what is the same, "0" pollution and local resources.
HEMP. The house is 200 years old and suffered from a huge problem of rising damp. After evaluating options, they took a risk and decided to use it. They are pioneers in the islands in the use of hemp, and they hope to be an example for other architects. In Mallorca, and in almost all of Spain, this material has not yet been worked on due to ignorance and lack of companies that manufacture it (in 1961 the United Nations prohibited its cultivation, now lifted). Hemp is suitable for areas with high ambient humidity such as the island, since the hygrothermal regulation caused by this material increases comfort and saves energy.
They use hemp on the roofs due to its very high thermal capacity (three times higher than conventional treatments), and in the walls separating rooms due to its extraordinary acoustic capacities (high density). We learned that the raw energy consumed in its manufacture is very low, fast growing and easy to cultivate. It is healthy and highly durable. They have to know that the use of hemp in construction contributes to sequestering, and even reducing, greenhouse gases during the useful life of the building. Without a doubt, it is one of the materials of the future since it is also beginning to be used as a structural system, penalizing our esteemed concrete.
To make this rehabilitation an environmentally effective place, first of all, they had to consider what to do with the rubble generated by the work. Two maxims to begin with; reuse and recycling. The rubble from the demolition has been used to consolidate façade walls. The “marés” blocks from the old dryer have been used for the new furniture in the kitchen and bathrooms. The existing, very deteriorated pavement has been given a second life, reusing it in the lintels of the new openings in the façade. All of this contributes to reducing the use of the planet's resources.
Ideo Arquitectura have kept the northern pine (also from Mallorca) in mind for the doors and windows of the facades. They have endowed the carpentry with enormous personality with a new system of pre-frame-frame in a single piece in the shape of a "T" that Virginia del Barco has invented. The design responds to the lack of flatness of the interior facings of the 70 cm thick walls. Why not leave the gaps free and place all the carpentry on the inside face of the wall? Ideo Arquitectura did that. The "T" is embedded in a wound in the wall made for this purpose to consolidate the frame, and all the carpentry is directly visible. Again, the material in its essence, our goal always.
Lime construction is an ancient technique in Mallorca. Until now, it was only used on facades and vertical walls. They have dared and have also used it on floors and ceilings. The result of aesthetic and plastic continuity throughout the interior reveals an atmosphere of peace and calm, one of the few customer requirements.
建築師運用馬略卡島的北方松，打造立面門窗，也請木工發揮特色，採用新的預鑄系統。木構件由建築師維吉尼亞・戴爾・芭可（Virginia del Barco）發明，為單一的T型木件。這項設計能解決室內七十公分厚的牆體不夠平的問題，可保留牆面的平面落差，木作則完全嵌入室內牆面以內。T型木件嵌入牆體內特地打造的開口，以鞏固框架，而所有的木作都清晰可見。如此建材即可保留其特質，也吻合設計者的目標。
