Design for an eco-friendly community is an architectural competition advocating the use of bamboo as a building material. The competition takes place in a virtual rainforest in Second Life. Read more
Our submission aims at uniting the natural properties of bamboo with sophisticated modern construction techniques. High tech equipment and computer simulations should be utilized to analyze the climate, terrain, local materials and weather in order to enable the utmost simplicity and effectivity in the design of the structure. You need not compromise on quality of living or aesthetics in order to value ecology. The project showcases bamboo as a modern construction material with many uses beyond the 'Tiki Hut'.
Bamboo is an amazing material, its tensile strength is close to that of steel and its compressive strength twice that of concrete. Its hollow structure makes it strong because the equivalent shape filled would simply have more deadweight. Bamboo is interesting because its is one of the fastest growing plants in the world and therefore highly renewable.
The house is constructed mainly in woven bamboo. Heat shaped construction bamboo creates a solid framework and structural elements of four black bamboo canes each lifts the construction about six meters above ground. In order to avoid moist damage to the canes and to insure a stable and unobtrusive construction the structural elements are mounted in a steel plate and bolted to a concrete pad foundation. The pad foundation has a low impact the environment and is easy to establish in rough and soft terrain.
The construction is to be build in a tropical climate. Because of the high humidity and temperature it is raised six meters above ground. That way moist damage to the construction is avoided and the breeze can flow through the building. In the woven shape there is plenty of room for insulation to sustain a comfortable temperature and the raised structure casts a shadow beneath the building. This cool shade can be utilized for a terrace or simply a hammock. Outer blinds serves to regulate light and heat from the sun. Windows are made in a special fabric that allow for natural ventilation but keeps out the rain.
The structure is constructed in order to be adaptable to the changes in climate, more insulation can be added and the airflow and light can be regulated.
Cradle to Cradle
The Structural elements can easily be removed from the concrete foundation since it is bolted in place and not hardened. The light woven frame can be removed as panels. The heat shaped framework can be taken apart as independent rips. This allows the construction to be relocated and reused over and over again. The individual elements can also be used for other purposes.
A special thanks to Natalie Mossin neighbour and architect at Building Lab DK for guidance and lending me a library of great architectural books.
