Earth House by BCHO Architects

BCHO Architects have completed this house buried in the ground in Seoul, Korea to honour the late Korean poet Yoon Dong-joo.

The concrete-lined residence has two courtyards with earth floors, to which all rooms are connected.

The earth used for the walls is from the site excavation. 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.

Rammed Earth walls provide all the interior spatial divisions and the walls facing both courtyards.

Rammed-earth walls make use of the excavated earth while wood from a pine tree from the site is embedded in the concrete courtyard walls.

Bio-Engineered Sand Brick

The winner of the 2010 Metropolis Next Generation Design Competition proposes a radical alternative to the common brick: don’t bake the brick; grow it. In a lab at the American University of Sharjah, in the United Arab Emirates, Ginger Krieg Dosier, an assistant architecture professor, sprouts building blocks from sand, common bacteria, calcium chloride, and urea (yes, the stuff in your pee). The process, known as microbial-induced calcite precipitation, or MICP, uses the microbes on sand to bind the grains together like glue with a chain of chemical reactions. The resulting mass resembles sandstone but, depending on how it’s made, can reproduce the strength of fired-clay brick or even marble. If Dosier’s biomanufactured masonry replaced each new brick on the planet, it would reduce carbon-dioxide emissions by at least 800 million tons a year. “We’re running out of all of our energy sources,” she said in March in a phone interview from the United Arab Emirates. “Four hundred trees are burned to make 25,000 bricks. It’s a consumption issue, and honestly, it’s starting to scare me.” Read more…

Modern Rammed Chalk

Dan Brill Architects has designed a £50,000 extension to an Edwardian home on the outskirts of Winchester using rammed chalk. The chalk, which makes up the soil of the site was considered as it is a traditional technique in the region and because of the large amount of excavation required to accommodate the addition.

The clients, who wanted something contemporary and innovative, appreciated rammed earth and more so the pristine appearance of the stark, white chalk walls. The material has been used in modern construction in the Pines Calyx project. It was also used in the construction of eight experimental cottages at the Department of Industrial Science and Research at Amesbury between 1919 and 1921. Construction is slated for later this year.

Oaxaca School of Plastic Arts by Mauricio Rocha

The Oaxaca School of Plastic Arts was designed by Taller de Arquitectura—Mauricio Rocha at the request of artist Francisco Toledo, in collaboration with the Benito Juárez University. An important premise incorporated into the project was the presence on the plot of land of a Mixtec ball game, used on weekends by players.

Several campus construction project occurring at the same time made available a tremendous amount of earth, inspiring Rocha to construct several of the buildings within complex out of rammed earth. This enhanced the quality of the exterior courtyards and created a comfortable micro-climate within the building optimal for Oaxaca. Other buildings are made of stone and create a series of inhabitable terraces.

Exterior courtyards suggest a floor layout in the shape of a chessboard, where the alternation between mass and space in the walkways creates a variety of views and paths.

Casa Entre Muros: A House Between Walls

The Casa Entre Muros, built in Tumbaco, Quito, Ecuador and designed by al bordE Arquitectos (David Barragán and Pascual Gangotena), was generated from the starting point: “There is always another way of doing things and another way for living”. Far from the pollution of the city, the house is set in the hillside of the Ilaló volcano in a indomitable land. It’s limited by two streams opened to the landscape of the valley. A cut in the sloping land helps to generate a platform for the project and also to get enough raw material to build the massive party walls.

The waving form as a result of this cut in the land, defines the position and order of every wall. The succession of rammed earth walls and the different heights of the roof caused the division of the house even for the activity or the user. To avoid the domino effect, the party walls break their parallelism solving the structure and strengthening the character of each space within. A long corridor is used as an element that isolates the project from their immediate neighbours and reinforces the autonomy of every space.

This architecture aims to highlight the nature of the material elements that compose it, promoting the aesthetic, formal, functional and structural qualities as well as the maximum respect of the environment.

Martin Rauch Builds His Own Home

Notable rammed earth building Martin Rauch, with the assistance of architect Roger Boltshauser recently completed his own rammed earth home in Schlins, Austria. The house which was finished 2008 reacts in its position and in its character directly to the topographic gradient of the slim plot and its genuine landscape context: A monolithic structure becomes a sculptural bloc, an abstract and artificial nature pressed upward from the underlying earth.

Haus Ihlow

Berlin based architect Eike Roswag’s Haus Ihlow is a renovation and addition to a historic stone barn using rammed earth built in the country side near Berlin. It is the first load bearing housing project in Germany since the 1950s. The construction is based on the “Lehmbauregeln”, but build with surprisingly thin walls (30cm) and large openings for windows.

The house has passive solar heating with a 60 m2 hot water collector and can store 4,000 liters of water supplemented by a wood fire place, connected to a floor and wall heating system. The owners use rain water for toilets and do wastewater treatment before draining the water on their own ground. Roswag’s firm, werk_A has many other projects in rammed earth.
