NEW DIGS: Accessories designer Jérôme Dreyfuss held a cocktail Tuesday night to inaugurate his signature label’s new showroom at 31 Rue Charlot in Paris’ Marais district.

“It was my dream to design it and build my own house,” he said, explaining that it took six months to sketch the plans. “I have had a big passion for architecture since I was a kid.”

His grandparents were good friends and neighbors of Jean Prouvé, so Dreyfuss’ exposure to architecture started at that point. He said he’s an admirer of the modernist movement.

“I am a huge fan of all the Japanese architects, all the Brazilian architects and all the French ones — from the Thirties until the end of the Seventies,” he explained. “The house is just a mix of everything I like.”

The concrete walls wink to Oscar Niemeyer, for instance, while interior bow windows give a nod to the likes of Le Corbusier.

The wooden structure is ecological, with plants in a central courtyard and soon to be sprouting on the roof terrace. There are also metal columns and a communal kitchen/eating area.

“It’s important to show my world to the client,” he said, adding the conception of the building was somewhat similar conceiving a bag or shoe collection — with the intent of being helpful and practical.

The three-story building, which is set back deeply from the street through courtyards, had formerly been a dilapidated factory. To construct the sprawling 7,220-square-foot showroom-cum-office, Dreyfuss added land.

His prior Paris showroom had been located on Place de la Bastille.

As reported, Dreyfuss in late 2015 opened his first store in London, a cozy corner that faces Bruton Street and Berkeley Square that measures 1,728 square feet. It was the designer’s eighth store globally.

Prior to that, his brand had opened units in Manhattan’s SoHo, Seoul, Tokyo, Taipei and Paris.
