When I was nine years old, my mom asked me what I would want my house to look like, and I drew this fairy mushroom. And then she actually built it. (Laughter) I don't think I realized this was so unusual at the time, and maybe I still haven't, because I'm still designing houses. This is a six-story bespoke home on the island of Bali. It's built alm... Read More

Key Insights

• 🏡 Using bamboo as a building material allows for unique and sustainable architectural designs, such as a six-story bespoke home in Bali that is almost entirely made from bamboo and includes features like curving roofs and woven pods.
• 🌱 Bamboo is a sustainable material that grows on otherwise unproductive land and can be harvested in just three years, providing a viable alternative to timber.
• 💪 Bamboo has impressive strength, with the tensile strength of steel and the compressive strength of concrete. It can withstand heavy loads and is lightweight enough to be lifted by just a few people.

Q: How does the speaker describe the properties of bamboo?

Bamboo is a wild grass that grows on unproductive land using rainwater, spring water, and sunlight. Out of the 1,450 species of bamboo, they use only seven of them. Bamboo is lightweight but has the tensile strength of steel and the compressive strength of concrete.

Q: Why did the speaker's father choose bamboo for building Green School in Bali?

The speaker's father chose bamboo for all the buildings at Green School because he saw it as a promise to the kids—a sustainable material that would not run out. Bamboo is abundant, strong, elegant, and earthquake-resistant, making it a perfect choice for the school.

Q: What is Ibuku and what does it do?

Ibuku is a team of artisans, architects, and designers founded by the speaker and some of the original builders of Green School. They are creating a new way of building using bamboo. Over the past five years, they have built over 50 unique structures, including homes and classrooms.

Q: How did they overcome the challenges of using bamboo as a building material?

They needed safe treatment solutions for bamboo to protect it from insects. By using borax, a natural salt, they were able to turn bamboo into a viable building material. They also aimed to build something extraordinary to inspire people and change their perception of bamboo as a poor or rural choice.

Q: What are some of the innovative design elements they incorporate into their bamboo structures?

Due to the curving and tapering nature of bamboo, they had to invent their own rules and design techniques. They ask the bamboo what it is good at and design accordingly, respecting its strengths. They create scale structural models from bamboo, design round doors, weave ceilings, carve kitchen countertops from boulders, and use handmade bamboo pins for structural connections.

Q: How do they approach the durability of their bamboo structures?

While the structural connections are reinforced with steel joints, the majority of their buildings are handmade using bamboo. They use whittled bamboo pins and thousands of them in each floor. They also employ techniques like using bamboo skin for glossy and durable floors, creating textures that affect the way people walk.

Q: How do they ensure the longevity of bamboo structures?

By treating bamboo with borax and designing carefully, the speaker mentions that a properly treated bamboo structure can last a lifetime. Treating bamboo protects it from weathering and ensures it does not get eaten by insects.
