The geniuses Gaudi and Pere's adventures with early 20th century windows
Interviewer: Shunsuke Kurakata (architectural historian)
"I want you to see Antoni Gaudi's windows. They were a pioneer of modern architecture, just before Wright and Mies. Your eyes will be drawn to the sculptural buildings, but if you focus on the windows, you will see that they are actually modern engineering structures."
Kurakata is referring to Casa Batlló, which was renovated by Gaudi.

Renovation: 1906. An apartment building in Barcelona, Spain, originally built in 1877, was renovated by Antoni Gaudi. The large glass windows that open onto the street are a distinctive feature of modern architecture. Some of the windows have louvered windows at the bottom for ventilation.

"The size of the windows was out of the ordinary for the time. By separating the windows from the structural pillars, large glass surfaces were created, and in some cases the upper part was divided into a light window and the lower part a ventilation window. The way the windows are designed controls the way light and air circulate."
Just as blood circulates through the human body, architecture becomes organic when invisible elements circulate well. This is what Gaudi believed. The shape of the windows and the complex structure of the buildings were all created with the circulation of air, heat, and sound in mind.
"Why is Gaudi's architecture so full of life and so moving? The answer is revealed in his windows."

The architect Auguste Perret, who was also Le Corbusier's mentor, created the windows as huge surfaces of light using exposed concrete and colored glass.
"Notre-Dame de Le Raincy is a building that receives light from all sides. Perret, who pursued concrete architecture, also created bold windows of light by freestanding the structural columns, just like Gaudi."
What is astonishing is that these beautiful windows are made by assembling countless factory-made concrete parts. "These challenges of their generation led to the ever-expanding adventure of the modernist window."
