WHAT OTHERS ARE SAYING
“For Guillaume Coutheillas, work is inextricably tied to style.”
–San Francisco Magazine
“Coutheillas’ studio is famed for cultivating collaborations between forward-thinking design brands, and this exhibition is no different.”
–Aspire
“Coutheillas flips the traditional approach to real estate on its head by partnering with galleries, artists and developers to introduce their pieces to potential buyers.”
–Robb Report
“His company offers soup-tonuts branding for real estate projects ... and Coutheillas sees the design of a sales gallery or a model residence as a natural extension of that work.”
–AN Interior
“The creative connoisseur assembled a team of equally keen and imaginative tastemakers for the job.”
–New York Interiors
“I’ve had a personal relationship with Guillaume going on a decade. I trust his taste, his aesthetic. We originally were in talks just for the web presence, but it became a logical extension to do the model unit.”
