Napa Valley Rammed Earth House

THE first clue that a visitor to Tatwina and Richard Lee’s hilltop property is headed somewhere unusual is the approach, as it’s known in landscape design parlance. The nearly half-mile of dusty road winds dramatically up an intermediary ridge of the Diamond Mountains above Napa Valley. Each turn raises the expectation that the house will soon appear, as houses normally do, but even when the gravel parking area at the top is finally reached, there’s no sign of a house or a garden, just a simple path of crushed stone edged with mounds of green-gray Sonoma sage and California lilac. This, it turns out, leads over a rise to a low, rammed-earth house hidden on the other side.

The house — really a line of four one-story buildings made of earth, concrete and steel and designed by Steven Harris Architects— sits in the depression between two knolls on a narrow, rocky peninsula, with steep, pine-covered hills swooping down on three sides to vineyards famous for their cabernet sauvignon.

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.

Ancient Rammed Earth Observaory

Only recently rediscovered. An ancient site in the port of Qingdao has revealed the oldest known observatory in China. The Chinese Astronomy Society, learned of the finding at its annual convention. Experts point to historical evidence, that the Langya Observatory in east China’s Shandong Province, was built during the Warring States Period— more than 22-hundred years ago. The three-storey structure stands about nine meters. The original structure was made of rammed earth. The observatory was evidently erected as a site for studying the stars as well as for monitoring conditions at sea. [ Watch ]

North American Rammed Earth Builders’ Association

The North American Rammed Earth Builders’ Association (NAREBA) is a not for profit entity that offers the opportunity for its members to share in the passion for working with earthen materials and to contribute to the advancement of RE construction. NAREBA builders share a resource base of over 150 years of collective building experience and have committed to building RE walls with the highest standards in the industry.

Clan Homes in Fujian

Clan homes in Fujian by Jens Aaberg-Jørgensen, originally published in Danish in ARKITEKTEN no. 28, November 2000, pp. 2–9, is an exceptional resource of photos, drawings and documentation of the round, rammed earth miniature circular castles, constructed from the 11th to 20th centuries that are shared by entire clans; their circular shapes, single point of entry, and weapons portholes were designed to optimize defense. As we reported previously, the structures were recently protected by UNESCO.

Tulou, the unique rammed earth buildings of Fujian Province in southeastern China, were added to the UNESCO World Heritage List on Sunday, during the 32nd session of the World Heritage Committee. According to the submission provided by China’s State Administration of Cultural Heritage, the Tulou buildings have been built since the 11th century. Designed to meet the requirements of a whole clan living together, they usually consist of a rammed earth outer wall and internal wooden framework, often of a circular configuration surrounding a central shrine.
