Paris’s 17th Arrondissement, near the city’s northwestern limits, is mostly residential, so it’s not typically front of mind for visitors to the French capital. But the opening of La Fondation, a 58-room hotel with interiors by the New York-based design firm Roman and Williams, might shift that mind-set. It’s part of a new 10-story complex that also includes an office space with rooftop gardens, a gym — which features a rock-climbing wall, 80-foot-long pool and multiple fitness rooms — and a spa with saunas, a hammam and treatment rooms. Hotel guests get access to all of this, along with two French restaurants — a classic bistro and a fine-dining option, both helmed by the local chef Thomas Rossi — and a rooftop bar that offers sweeping views spanning from the Sacre Coeur to the Eiffel Tower. For the hotel décor, Roman and Williams referenced the city’s late Modernist period: rooms feature colour-blocked walls bordered by oak frames — a nod to Yves Saint Laurent’s 1965 Mondrian dress. In the common areas, large-scale commissions such as a wooden wall sculpture by the Croatian artisan Vedran Jakšić or the painted ceramic tiles by French artist Pierre Yves Canard, merge with the architecture. “There’s a constant interplay between refinement and rawness, fashion and function, Paris then and now,” says Robin Standefer, a co-founder of Roman and Williams.
