Klein bottle

"A three-dimensional object in which there is no distinction between inside and outside."

An extended version of the Möbius strip → The surface is connected → If we create it in our 3D space, we will inevitably break through it midway.

When it becomes an architectural space

• As I was walking down the corridor

• Without realizing it

• It's on the back side of the building

• Neither the walls nor the floor are cut.

• A single continuous surface

"Architecture where the interior and exterior disappear"

都市スケールの有機生命体

都市の地形　SECTION

The ground rises, and a soft, membrane-like surface appears in the city.

People walk there and before they know it, they're inside the building.

Suddenly, the sky becomes visible, but I'm still walking on the same floor.

Like a giant balloon.

There is no moment when you enter the building.
