Studio GGSV was founded in 2011 by Gaëlle Gabillet and Stéphane Villard. Their collaboration encompasses a diverse range of approaches, from curating to research design, from objects to interior architecture. In parallel, Stéphane Villard leads the INFORME project studio at the École Nationale Supérieure de Création Industrielle, ENSCI / Les Ateliers, Paris.

They were awarded the VIA Carte Blanche in 2011 for their project "Objet Trou Noir." This research project, recognized by VIA, explored the use of "black matter" derived from ultimate waste and reinterpreted household appliances in connection with tableware and decorative arts, focusing on the concept of decluttering.

"Objet Trou Noir" is now part of the permanent collections of the Centre Pompidou.

Gaëlle Gabillet and Stéphane Villard have their works published by Made in Design, Petite Friture, and Galerie Cat-Berro. Their pieces are regularly exhibited at various venues, including MUDAC, Pavillon de l'Arsenal, FRAC, Museum für Angewandte Kunst in Frankfurt, Biennale Design Saint-Étienne, Center for Contemporary Art Castle of Rivara in Turin, and the Milan Furniture Fair. Recently, they were responsible for the interior architecture of La Commune, the national drama center in Aubervilliers. They won the Paris Shop & Design Award in 2014 and, in 2016, they secured the interior redesign of the Musée d'Art Moderne de la Ville de Paris in collaboration with H20 architects.

They also serve as exhibition curators. They curated the exhibition "Form follows information" at the International Biennial of Saint-Étienne in 2015 and the exhibition "Zones de confort" at the Galerie Poirel in Nancy, along with Juliette Pollet, design curator at CNAP (National Center for Visual Arts). They were invited to celebrate the 40th anniversary of the Centre Pompidou and create a workshop-exhibition at the Galerie des Enfants.

Gaëlle Gabillet and Stéphane Villard regularly give lectures about their work at various institutions and events, including the Centre Pompidou Paris, Université Paris 8, Pavillon des Arts et du Design, Cité du Design, Musée des Arts Décoratifs, Cité de la Mode et du Design, Maison & Objet, OECD, Ecole Camondo, and Ecole des Hautes Etudes en Sciences Sociales.
