But both sprang from the imagination and innovative spirit of Jeanne Gang, a 2011 MacArthur Fellowship winner described by the foundation as "an architect challenging the aesthetic and technical possibilities of the art form in a wide range of structures."
"The way that I start a project is by thinking of working with a material and working within the many constraints of the project," says Gang.
"A lot of people these days start with a form and then try to work the functions and the materials into it, and we really work from the other side of that."
The aforementioned Aqua building stands as a case in point. For all the visual poetry of the building's façade, with its distinct balcony shapes for each floor, Gang was trying to address the experiences of those who would live there, she says.
"The whole reason for doing a high-rise – making it possible for a lot of people to live in a very small footprint – is very appealing to me, because it's more sustainable," adds Gang.
"On that particular site, the whole idea is to be able to get views for people. By pulling in and out (the placement of the balconies), people can see in and out of buildings (nearby) and get views they wouldn't ordinarily see."
Yet this gently undulating effect was possible because Gang employed new technologies in shaping the building's concrete floor plates. By using the latest digital tools in her office and at the site, Gang could shape the concrete so that each floor of the building had a different contour.
"A lot of people treat (concrete) so it looks like stone," says Gang, "but it's liquid and capable of being fluid."
Another Gang creation unfolds inside Columbia College's Media Production Center, where film students learn to create the illusion of depth on the flat screen.
"We thought we would try to embody that in three dimensions inside the building," adds Gang, in explaining why she opted to "create windows that cut through the building, (so) you create these sequences of space," she says. The students are "learning how to make film, and they're in a space that's kind of compatible with it."
If Gang's rising international profile suggests she doesn't need the $500,000 prize or cachet of the MacArthur Fellowship, she offers another perspective. The money, she says, can underwrite research that's not funded by clients; and the MacArthur imprimatur holds personal meaning, she says.
"It's a vote of confidence that other people think that what you're doing is interesting and worthwhile," she says. "It's a vote for us for what we're going to do in the future."
