This waterfront address promises to be sublime. With only the Bassin de Chalais in view, the furnishings blend seamlessly into the environment. By reviving the fashion for canoeing, but also the codes of the guinguettes along the Seine, the Impressionist Masters are subtly summoned.

The layout is designed to reflect the natural environment in all its organic, living forms. The space opens onto the pond through bay windows. Retaining the building's exposed metal framework, origamitically-shaped wooden slat sub-roofs take shape, responding to the historic Hangar Y building designed by Henri De Dion. To complement this timeless venue, Guillaume Sanchez is integrating Hangar Y's culinary program.
