About
Stefan Al is an expert in urban planning and architecture who explores how cities can adapt to environmental challenges and push the boundaries of construction innovation. Through his work with TED-Ed, he examines critical questions about urban sustainability and architectural possibilities that shape how we think about the future of our built environment. His expertise spans from flood management systems and urban resilience to the frontiers of high-rise construction and sustainable building materials.
Stefan investigates practical urban challenges, such as how cities protect themselves from natural threats and what happens when urban ecosystems are disrupted. He also explores ambitious architectural concepts, examining whether revolutionary building techniques and materials could transform skylines and construction practices. Stefan's approach combines technical knowledge with accessible communication, making complex urban planning and architectural concepts understandable to broad audiences.
His work helps people understand the engineering marvels that protect cities and the innovative solutions that could define future urban development.

Could we build a wooden skyscraper?
Towering 85 meters above the Norwegian countryside, Mjøstårnet is the world's tallest wooden building, made almost entirely from the trees of neighboring forests. But as recently as the end of the 20th century, engineers thought it was impossible to build a wooden building over 6 stories tall. So how do wooden structures like this compare to steel and concrete skyscrapers? Stefan Al investigates. [Directed by Franz Palomares, narrated by Addison Anderson, music by Stephen LaRosa].
