Architecture
Look around you. Every wall, window, and roof is the result of human decisions. Architecture is the blend of science and art, ensuring that the places we live, work, and play are safe, functional, and inspiring. Let us explore how we build our world!
The Invisible Framework
Structure holds it up, infrastructure makes it work! The structure is the beams and walls. The infrastructure comes from Latin words meaning "the structure underneath". It includes all the hidden pipes, electrical wires, air conditioning ducts, and fire sprinklers that keep the building functional.
They use flexible wooden joints and no nails! These incredible centuries-old buildings feature a massive central column and loose, interlocking wooden pieces. When the ground shakes, the joints flex and absorb the vibrations instead of snapping under the pressure.
Test Your Engineering Instincts
Think about the materials and shapes needed to construct massive structures. Pick an answer below to test your knowledge.
Stone is too heavy! While stone is incredibly strong under compression, it is incredibly dense. If you stack stone columns too high, the massive weight will cause them to bow, flex, and eventually collapse. Steel is much stronger for its weight.
The Triangle! A triangle cannot be deformed without breaking its sides. Architects use series of triangles, known as trusses, to hold up massive roofs and heavy bridges!
The Science of Design

Key Concepts
Form Follows Function
Tap to learn moreThis is the golden rule of architecture. It means a building's shape (its form) must be based directly on what the building will be used for (its function). A firehouse needs massive doors, while a train station needs open walkways.
Foundations
Tap to learn moreA building is only as strong as its base. A narrow building will easily topple over, but distributing the weight across a much wider, solid foundation allows architects to build structures incredibly high into the sky.
Architectural Views
Tap to learn moreArchitects use three main drawings to explain a 3D building on flat paper. The Elevation View shows the outside straight on. The Section View shows a slice of the inside. The Plan View shows the floor layout from the top down.
Trusses & Triangles
Tap to learn moreBecause the triangle is the strongest physical shape, builders connect parallel beams using triangles to create a truss. These interlocking frameworks are incredibly stiff and are used to support massive roofs and bridges.
Arches & Domes
Tap to learn moreAn arch carries the weight of a roof along its curve directly down into the outside walls. A dome is just a circle of arches hooked together. Both designs allow architects to create huge open spaces without needing central columns.
Geodesic Domes
Tap to learn moreA geodesic dome is a spherical structure built entirely out of interlocking triangles. It is an architectural marvel because it surrounds the greatest amount of volume using the least amount of surface area and building material.
Steel Frameworks
Tap to learn moreModern skyscrapers are built using internal skeletons made of steel I-beams (beams shaped like the letter I). Steel frameworks are significantly stronger and lighter than stone, allowing us to build hundreds of storeys into the sky.
Infrastructure
Tap to learn moreIt is not just about the walls! Infrastructure refers to all the vital systems mapped out in the plans. Without carefully placed water pumps, transformers, and air filters, a building would be completely uninhabitable.
Interactive: Structural Stress Simulator
Test the structural integrity of different architectural designs! Select a building blueprint, then subject it to severe environmental hazards to observe the physics of material flex, tension, and load distribution.

Design Challenge: The Wind City
Imagine you have been hired as the lead architect to design a new skyscraper in a city famous for high winds and frequent, minor earthquakes. Based on what you have learned about building materials, foundations, and shapes, write a short paragraph describing three specific architectural features you would include to keep the building safe and stable.
What Has Changed Since This Episode Aired
This episode originally aired in 1997. Since then, the worlds of engineering, materials science, and digital design have completely transformed architecture!
Then (1997): Architects relied on flat paper blueprints and tiny cardboard scale models to plan buildings.
Now: Engineers are using massive, robotic 3D printers to extrude concrete and literally print entire, full-sized houses layer by layer in a matter of days!
Then: If an architect changed a wall on the paper blueprint, the plumber and electrician had to manually redraw all their infrastructure plans.
Now: Advanced 3D software allows the architect, engineer, and plumber to work on the exact same digital model simultaneously. If a wall moves, the software automatically warns the plumber that their digital pipes need to be moved!
Then: Infrastructure consisted of standard, fixed electrical wiring and water pipes.
Now: Modern buildings are wired with the Internet of Things (IoT). Thousands of hidden sensors automatically track where people are in the building, instantly adjusting the heating, dimming the lighting, and controlling the airflow to save massive amounts of energy.
Then: Dr. Kobori studied how ancient Japanese pagodas used flexible wooden joints to survive earthquakes.
Now: To protect modern super-tall skyscrapers from earthquakes and high winds, engineers suspend massive, multi-tonne steel balls near the roof. These "tuned mass dampers" act like giant pendulums, swaying in the exact opposite direction of the building to cancel out the vibrations!
Then: The rule was "form follows function," with a primary focus on human utility.
Now: Architecture is at the forefront of fighting climate change. Modern "green" buildings incorporate living roofs covered in grass, vertical forests on the balconies, and passive cooling systems that use natural wind to completely eliminate the need for air conditioning.
