Earth House, Switzerland

The house is located in Switzerland. People call it "Earth House" as part of the wall is made of residential mounds planted with ornamental grasses. So the impression that the house is shown together with the surface of the Earth. Grass accents also appear on the page.
In order not to damage the plant ornamental grasses, the homeowner gives footprints so that people are free to walk in the yard as well as the park.


An earth house (also known as the embankment soil or earth sheltered home) is an architectural style characterized by the use of natural terrain to help form the walls of the house. An earth house is usually set partially into the ground and covered with thin growth. Modern earth houses are built with concrete walls and insulation.

Unlike traditional residential houses built on the land, the aim of building an earth house does not live under or in the ground, but with it. If ground and house are separated, the house is built "into the air", which resulted in the loss of heat and moisture, and the loss of life of the building exterior shell. Earth house concept uses the ground as an insulating blanket that efficiently protects from rain, low temperatures, wind and natural abrasion.

The main entrance to the house earth sometime in the roof.
An earth house does not have to be built under the ground, it can be placed onto naturally grown terrain. Earth house is a flexible construction that can be built in accordance with the wishes of the owner, to meet the requirements for individuality and energy conservation.
The structural engineering of an earth house creates for an organic design requiring spatial sense and creativity. Earth house architecture reminiscent inhabited sculpture, incorporating artistic claim and quality of sculpture.
The entrance to the house earth to the roof. Home early earth had no windows, but modern earth houses can have windows on the roof that can mean more natural sunlight than their entry in an average home. Houses earth does not have to be simple in design and low cost, "The Burrow" in Canterbury, England, went on sale for £ 2 million in May 2007. It featured five bedrooms and was designed by Patrick Kennedy-Sanigar, who is now trying to build a "village" using this type of housing.

Structural engineering

Meshed metal stretch net construction
The structure, designed as integral arches, can be constructed as stiff individual objects or by means of sprayed concrete procedure. Arches made of sprayed concrete provide free form and organic, allowing the space to be filled with light. Sprayed concrete procedure was first used by the natural scientist Carl Akeley in 1911. Akeley patented a device able to spray smooth concrete. While sprayed concrete is mainly applied in underground engineering and tunnel construction, Friedrich Kiesler was the first to use this technique for building construction. Swiss architect Peter Vetsch improve the technique for several years. To date, he has built more than 40 homes using concrete sprayed earth, and therefore it can be regarded as a leading authority in the field of keahlian.The sprayed concrete applied to finely meshed nets that stretch metal welded to the supporting armature. The curves are bent and shaped according to the desired shape of the building. A 20 cm thick polyurethane solid-foam-insulation is sprayed onto the outside of the arch, to protect the house from the low or high temperatures. A fleece filter mat is then placed on top and the building is covered with a thick layer of soil some 80 cm to 3 meters thick. The foundations of the building were designed by Peter Vetsch are built conventionally. The Earth's interior walls fitted using loam rendering which provides superior humidity compensation. Loam rendering is finally coated with white lime cement paint.

Design and architecture

The interior of the house earth

Earth houses by exponents like Peter Vetsch or Arthur Quarmby based on the interpretation of architecture, ecology environmentally conscious and progressive. They stand out due to their closeness to nature and allow the experience beyond the four walls of their regular and right angles. Earth house concept uses the environment as an advantage - the surroundings are not adapted to the building, the house was formed in order to preserve the natural environment. Modern earth-house architecture incorporates the latest interior finishing, such as contemporary kitchens, bathrooms and home-control system. In addition, each new home is designed in accordance with the wishes of the owner. Each house of the earth so it can be regarded as an object that is very individual. The focus of the planning process is a human being, who was given the opportunity to integrate the "third skin" into its own architecture. Earth houses can be built as a single dwelling house or housing.

Profit

The advantage of an earth house, especially ecological and security.
Insulation, energy and CO 2 savings
One major benefit of the ecology of the earth-house architecture located in a natural insulation. Unique architecture house cool down in the summer and warm in winter. A further advantage is the higher humidity from 50 to 70% compared to conventional home overheated room in the winter. In addition, as the earth penetrated, they can be considered ideal for AC control.
Windstorm and earthquake protection
Unique architecture of earth houses protects them against severe windstorms. They can not be torn apart or pushed winds. Structural engineering and, above all, lack of corners and exposed parts (roof), eliminate vulnerable surfaces which would otherwise suffer from storm damage. Furthermore, earth houses benefit from improved stability due to a more natural arch.
Landscape protection and land use

Compared to a conventional building, earth houses fit into their surroundings. Soil-covered roof helps integrate the environment, protecting natural landscapes, and contribute to the oxygen-nitrogen balance of the soil, which should be covered by the foundation fixation, nitrogen traditional home hampers and soil aeration. Contrary to conventional roofs, earth-house roofs to restore the surface area that can be used for the environment. They can also be built as a multi-storey structure if appropriate slope, so that land use is much less, because the structure can be built up to the property boundary. Because construction means thick, more green space remains available. In addition, the earth-house structures can easily be built into the hill, as opposed to a conventional house, which will require flat land.
Fire protection
Compared to other building materials, such as wood, earth houses because it features an efficient fire protection for the use of concrete and insulation provided by the roof.
planting Roof
Roofing done using minerals that allow for useful plant. As the roof to collect and bind most of the rain water, the river and the sudden release of large amounts of water.
Light
Earth houses can be built using wide glass façades and dome-lights, allowing the room to be bright and filled with light. Dome-lights provide natural light for bathrooms and secondary rooms.
Structure and Resilience survivability
Because the mass of the earth between the living room of a house and grade earth surface, the earth offers significant protection from impact / blast damage, or associated with a nuclear bomb fallout.

Disadvantages

Specific architecture of the earth usually cause non-corrected, round the walls, which can cause problems on interior decoration, especially the furniture and large paintings. However, this problem can be anticipated during the conceptual design of an earth house.
Unless properly ventilated, earth-sheltered homes can have very high levels of moisture, causing mold or mildew growth. Orientation many underground earth sheltered home can allow accumulation of radon or other unwanted material.
Despite the large window (usually facing south), earth sheltered homes have many dark areas in the opposite window. All the natural light coming from one side of the house can provide a "tunnel or cave effect". This can be overcome with the strategic use of skylights, solar tubes, or other sources of artificial light.
