Eddy Residence

Michael and Lisa Eddy dreamt of living in a home that was designed to showcase their love of nature and appreciation for the environment around them in Colorado. Designed by JCL Architecture, their fantasy home made of rammed earth is characterized by a continuous trellis that greets you at the entry and leads you through the warmth of the house and out into the open backyard towards the landscape beyond. Aside from being beautiful, the house incorporates passive solar strategies and high thermal mass. Proper roof overhangs and southern exposure were calculated to allow maximum solar gain in the winter while minimizing heat gain in the summer. The thermal absorbent qualities of the rammed earth walls and dark stained concrete floors on both levels stabilize temperature swings from night to day and mitigate the need to run an air conditioning unit during the summer. These features are then further supported by a high-efficiency geothermal radiant floor heating system as well as soy-based insulation in the roof and walls.

Adobe Homes for All Climates

Adobe Homes for All Climates: Simple, Affordable, and Earthquake-Resistant Natural Building Techniques, by Lisa Schroder and Vince Ogletree, is ideal both for first-time do-it-yourselfers and for experienced adobe builders seeking to improve their craft. Drawing on the experience of more than fifty major adobe projects since 1993, Adobe Homes for All Climates describes Adobe Building Systems’ patented reinforcement and scaffolding systems, showing readers how to construct adobe homes more easily and safely, and with superior strength, durability, structural integrity, and aesthetic appeal, as compared to earthen homes of the past.

Computer Modeling to Build Better Mud Bricks

Rammed earth and stabilized mud block or brick are cheap, easy to make, usually durable materials widely used for building homes and low-level structures, especially in developing countries. Despite their widespread use and long history, the structural properties of these materials are not well understood, so how they could be manufactured to better withstand destructive natural forces, such as earthquakes and weathering, remains a goal. Craig Foster, assistant professor of civil and materials engineering at the University of Illinois at Chicago, hopes a specially tailored set of computer models he is developing may provide the necessary answers. He has just won a three-year, $243,000 National Science Foundation grant to conduct the work.

Emerging Ghana

Enviu selected Emerging Ghana by Ana Morgado, João Caeiro, Lara Camilla Pinho, Maria de Paz Sequeira Braga and Maria de Carmo Caldeira, from Portugal, Mexico and Brazil, as the winner of the Open Source-House competition. The materials used are bamboo and dahoma, a local wood, for the modular and lightweight panels. These are held together with strong rammed earth walls. Due to the modular design, inside and outside spaces can be created depending on different needs and environments. Natural ventilation is archived throughout the building, due to the earth walls that keep the spaces cool and shaded areas.

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.

EARTHWORKS: International Summer School

EARTH WORKS: International Summer School will take place September 1st – 18th, 2010 in Gmunden, Upper Austria. Instructed by Martin Rauch and Anna Heringer, the aim of the summer program is to acquire intensive hands-on experience and to gain application-oriented knowledge in buiding with earth to associate this timeless material to innovative architecture. The central focus in to obtain practical experience and to learn by doing.

The program is jointly organized by BASEhabitat, the Technical University Munich , CRATerre-ENSAG and the UIA. Closing date for application: 28th of June 2010. For further information and online-application, please visit www.basehabitat.ufg.ac.at

How to Survive the Coming Bad Years


How to Survive the Coming Bad Years, 2008. Soil, straw, water, timber, lime and ceramic pipes. Attingham Park, Shropshire, UK. Commissioned by Meadow Arts for the exhibition Give Me Shelter

In an ancient woodland at the core of Attingham’s vast 4,000 acre land, an immense clay structure rises through the trees like an oversized Dalek. Both alien and primeval, How to Survive the Coming Bad Years, by Heather and Ivan Morrison, is inspired by traditional rookeries found throughout the Middle East where in return for shelter, the birds provide squab to eat and guano to fertilise the land on which food is cultivated. Ivan and Heather Morison’s huge lime covered cob sculpture suggests the vestige of an other worldly civilisation or perhaps a post-apocalyptic future. In this case the structure will provide a nesting environment for Attingham’s bird-life, but in return they must give up a share of their young.

Handmade Houses & Other Buildings: The World of Vernacular Architecture

Vernacular architecture, by its very nature, is built from local materials that are readily to hand and is thus defined by the geology and ecology of the region and by local climatic conditions. Constructed by the community using traditional tools, these structures are highly practical, energy-efficient, and blend with the landscape. They carry many of the attributes that we are now seeking in green architecture as we struggle to adapt our built environment to the demands and concerns of the climate-change era. Handmade Houses & Other Buildings: The World of Vernacular Architecture looks at everyday structures all over the world, from whatever wood, grass, earth or stone that was to hand, in ways that offered practical solutions to the challenges of climate or terrain. Based on immemorial principles, but highly relevant to our newly found environmental concerns, these buildings show the simple and satisfying ways in which humans have worked out how to live and live well, in harmony with their surroundings.

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…
