In hot and humid regions like Southeast Asia and parts of South America, bamboo has long been a go-to for architectural construction. However, the once-traditional material is now garnering increasing attention in modern architectural design around the world. The advantages of bamboo as building materials include strength, flexibility and availability (in areas where it is grown locally), promising well-ventilated and quickly-built spaces.
One reason that architects are now reconsidering the materials’ architectural potential is due to sustainability. Bamboo is a fast-grown, lightweight natural material that requires little effort in terms of cultivation. Research is mounting to investigate its potential as an alternative to steel (e.g. bamboo reinforced concrete); for now, it is more often used as a structural material that stands alone.
Located on the rural island of Chongming, Shanghai, this winding structure aims to bring vitality to an empty site by providing a stage for social interactions. The structure is held up by a bamboo skeleton and then wrapped in sliced bamboo strips to form half enclosed spaces. Eight different types of bamboo joints are designed to realize its curvy form.
This 425 foot (130 meter) long pavilion is an extended entrance that invites visitors into Jim Thompson Farm. The pavilion is a combined steel and bamboo structure. Bamboo strips and stakes are skillfully twisted and fixed to mimic the running Mekong river, while the steel portions of the building are disguised. Far from a random assemblage, the overall form and shape of the structure consists of 5 distinct parts, each referring to a significant geological feature of the Mekong river.
This bamboo pavilion is sited on ecologically restored land that used to be a refuse landfill. Several fully grown bamboo stakes became the frames of this wing-like structure. For more convenient maintenance, the project team used steel components to connect these bamboo stakes, ensuring that that could be replaced individually should the need arise. Between the frames are sliced bamboo strips that form louvre roofs; they create a sheltered feeling that simultaneously (and somewhat paradoxically!) reinforce the openness of the space.
Diamond Island comprises a series of bamboo pavilions that scatter on an islet next to the Saigon River. The pavilions covered in thatches can host a variety of events such as parties, banquets and conferences etc. Supporting these circular roofs are bamboo stakes that are bound and woven together. The tall roof structures shelter the space underneath, helping to avoid overheating not only by blocking the sun, but also by allowing the heat emitted from the ground to escape out the open walls. With the heat going upwards, cooler air near the water is drawn into the ground space, keeping it comfortable and ventilated.
The commission specifically required a large-span space to shelter different mega-events that normally include the whole town’s population, including seasonal tea trading, agriculture products trading, weddings and funerals. The project team chose the lightweight bamboo stakes to tackle this requirement. Sitting on walls of rammed earth and concrete, the roof that spans 60 feet (18 meters) wide consists of 4 layers of bamboo structure and is topped with timber planks, membranes and steel tiles.
The structure of this lotus-inspired sports hall is built entirely from bamboo, which results in its extremely low carbon footprint. The sports hall has a capacity of 300 people and accommodates courts for futsal, basketball, volleyball and badminton. The roof’s iconic wave harmonically resonates with the style of the surrounding buildings. Using bamboo stakes of different sizes, the project team bound large bundles of thin stalks that, together, form structural units that are as strong as a single thick branch would be. The aesthetic benefit of the former is to add visual diversity and intrigue.
On top of a post-war Vietnamese building stands this undulating bamboo structure. Flexible bamboo stakes are carefully bent to form this cave-like interior intervention. The ceilings, formed by smoothly woven bamboo stakes, create a cozy yet stunning environment for guests beneath them. The whole café is softly divided into subspaces by the bamboo vaults. In the backdrop of these spaces is the cityscape framed by the vaults.
These clouds of bamboo float on top of the circulation space between two performance spaces of a local show, Impression Sanjie Liu. The riverside site is backed by a continuous bamboo forest, which presents a relaxing natural context. Stretching 460 feet (140 meters) long, these canopies are hand-woven in a rather random way, using sliced bamboo strips to form subtle and organic shapes.
