He tracked down the organization that owns the apartment, the Association Auguste Perret, to see if he and his wife could rent the unit as a pied-à-terre. To his surprise, they said yes.
In the dining room, a marble-topped table by Eero Saarinen is ringed with Eames wire chairs. Through oak accordion doors, the atrium beckons with red Utrecht armchairs by Gerrit Rietveld and a yellow Diana table by Konstantin Grcic.
A framed vintage Michelin map of France—“the same one my parents used to drive us around,” says Claus—leans against the oak-paneled wall in the bedroom, alongside an AJ floor lamp by Arne Jacobsen and a lacquered metal Fronzoni 64 bed by A.G. Fronzoni.
The calf leather–upholstered banquette between the grand salon and the bedroom was designed by Perret and is original to the apartment; Claus likes to imagine that it’s where Perret would curl up for a nap.
Reflected in the bathroom mirror is a photograph of a Perret-designed building in Le Havre, shot by Dutch architectural photographer Kim Zwarts. “It’s impossible not to pay homage to him within the space,” says Claus.
Renting the apartment was a dream come true for Claus, who founded his firm in Amsterdam, but had always wanted to live in Paris. “Why? Anyone who’s visited the city will know the answer—it’s self-explanatory,” he says. He currently spends most weekends in his second home—“I couldn’t live here permanently; I’d find it too overpowering,” Claus says. He frequently throws parties for fellow design aficionados. “It’s fantastic for entertaining, simply because most of my friends and contacts, as architecture fans, are thrilled to have a chance to spend time here.”
