An interactive installation reconsiders the definitions of enclosure and openness.
Warren Techentin Architecture’s digitally-designedLa Cage Aux Folles, on display at Materials & Applications in Los Angeles through August, was inspired by a decidedly analog precedent: the yurt. “Yurts are circular,” explained Techentin, who studied the building type as part of his thesis work at Harvard’s Graduate School of Design. “That began the idea of using small-diameter rods and taking software and configuring sweeps with some special scripts that we found online.” But while the yurt’s primary function is shelter, Techentin’s open-air installation, built of 6,409 linear feet of steel pipe, is a literal and intellectual playground, its form an investigation of the dualities of inside and out, enclosure and openness.

Once the architects became familiar with the scripts, which allowed them to manipulate multiple pipes simultaneously, they found it easy to generate designs. The hard part was settling on a final shape. Then an off-hand observation narrowed their focus. “Somebody made a comment about, it looks like a crazy cage,” said Techentin. “We realized, ‘Oh, there’s this cage component. What if we imagine spaces inside spaces?’ That’s where these interiorized conditions came through, kind of creating layers of inside and outside.”
Technical constraints further influenced the form. “We had to jump out of the digital world and decide how this was made in reality,” said Techentin. To minimize materials costs, the architects decided to work with schedule 40 steel tube, which is available in 24-foot lengths. Returning to Rhino, they broke apart their model and rescripted it accordingly. They modified their model again after learning what radiuses their metalworking contractor could accommodate. “It was kind of a balancing act between hitting these radiuses, the 24-foot lengths, and repetition—but how do you get difference and variety,” said Techentin.

Warren Techentin Architecture originally sought a digital fabricator for the project. But the quotes they received were too high, and they could not locate a manufacturer able to work with pipes longer than six feet. They contacted Paramount Roll and Forming, who rolled and bent the tubes by hand for one-tenth of what digital fabrication would have cost. “It wasn’t what we wanted, but in the end we wanted to see the project through,” said Techentin. Paramount sent the shaped steel to Ramirez Ironworks, where volunteers interested in metalworking helped assemble the structure. The design and fabrication team then disassembled it, painted the components, and transported them for reassembly on the site, a small courtyard in the Silver Lake neighborhood.
La Cage Aux Folles invites active exploration. “My work draws great influence [from] architecture as something that you interface with, interact with—that envelops you, becomes part of an environment you participate with,” said Techentin, who overheard someone at the opening call his structure “a constructivist playground.” “We fully intended people walking around in there, lying down,” he said. “The surprise factor were the number of people who feel inspired to climb to the second and, more ambitiously, the third cages. We’re not encouraging it, but people do it.”
