Text description provided by architect.
Earth House is a house of the sky. It is a house built in honor of Yoon Dong-joo, a Korean poet, who wrote beautiful poems about the sky, the Earth, and the stars.
It is a house which focuses on the primal relationship between nature and humans. It is built with careful consideration of constructional efficiency and our somatic senses.
The 14m x 17m concrete box is buried in the ground and contains 6, 1-pyeong, rooms and two earth filled courtyards. The ‘small house’ is open to the courtyard which is open to the sky.
The one pyeong rooms originated from the size of one kan (6x6 ja; 1 ja = approx. 30cm) which are just large enough for an adult to lie down straight.
The house has a small kitchen, a study, two resting rooms, a bathroom with a wooden tub and toilet, and a wash room. The rooms are all adjacent to each other and open directly to the earth filled courtyard.
The lateral pressure from the earth on four sides is resisted by thick concrete retaining wall and a flat roof and base plate. There is also a hidden steel column in the center wall that reinforced the structural plates.
Connecting rooms can be joined to create a bigger room. The house doors are small, entering the house requires making your body into a smaller shape.
A combination of passive cooling and geothermal tubes which are buried in the earth around the buildings keep the temperature cool in summer and warm in winter.
Our hope is that this Earth House would be a house where we can reflect on ‘ourselves’ while living in the present era.
As Yoon’s poetry which he tried to achieve through self-restraint and self-reflection.
The wooden canopy protecting the entrance into the small house uses 39mm tensile wires.
Rammed Earth walls provide all the interior spatial divisions and the walls facing both courtyards. The earth used for the walls is from the site excavation.
A pine tree which was cut down from the site, was sliced into 80mm thick discs and was cast into the concrete walls of the courtyard so as it decays, it will host small plants and new life will arise with time.
The house uses a geothermal cooling system with a radiant floor heating system under the rammed clay and concrete floor. Off-peak electricity is used at night to heat the small gravel under the floor.
Even though the viscosity of the existing earth was low, only minimal white cement and lime was used so the earth walls can return to the soil later. Four gutters are placed in the corners of the courtyard for drainage.
