The cousins Cédric and Nicolas Hervet first partnered on a construction project as teenagers; their fathers, who are brothers, both had workshops filled with machinery that the boys used in an attempt to recreate the hoverboard they’d seen in “Back to the Future II.” “We took the entire thing seriously, sketching and welding an aluminum box that was filled with helium,” Nicolas says. “Our grandfather ran over the prototype with his car. Of course, in the end, it didn’t work anyway.”

More than two decades later, Nicolas, 39, and Cédric, 41, have successfully designed a collection of furniture and smaller items (an aluminum yo-yo, a leather cuff) under the name Hervet Manufacturier — and last Thursday, they opened their own showroom in Paris’s Second Arrondissement. The imposing block desks, swanky coffee tables and space-agey Le Satellite that houses a Bose sound system combine futurist forms, the highest quality wood and traditional woodworking techniques like marquetry and veneering. Nicolas, a furniture restorer by trade, oversees the production process in Normandy and ensures that every piece is up to snuff (as such, only a dozen are made in each style); Cédric, an École Boulle alum, handles the communications and business side.
