House raising
House raising (house lifting, house jacking, barn jacking, building jacking) is the process of separating a building from its foundation and temporarily raising it with hydraulic screw jacks. The process is the first step in structure relocation in which the building is moved to a different location. House raising may also be a part of a renovation to build a foundation under an existing house or make a house larger by building a new floor level creating a two story house. Often employed in areas that are prone to flooding and storm damage, this process can be achieved through the use of either timber piles or helical piles. Once a house is raised and supported on cribbing, a new foundation can be constructed beneath it. After Hurricane Katrina and Hurricane Sandy large numbers of houses in parts of Louisiana, New York and New Jersey were raised to avoid future flooding.
Earth house
Unlike traditional residential houses built on the ground, the aim of building an earth house is not to live under or in the ground, but with it. If ground and house are separated, a house is built “into the air”, resulting in the loss of heat and humidity, and the exterior shell of a building loses lifespan. The earth house concept uses the ground as an insulating blanket that efficiently protects it from rain, low temperatures, wind and natural abrasion. An earth house does not have to be built under the ground, it can be placed onto naturally grown terrain. The earth house is a flexible construction which can be built according to the wishes of its owners, fulfilling 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 brings to mind habitable sculptures, incorporating artistic claim and sculptural quality.
