David Smotrich & Partners LLP designed the first U.S. flagship day spa for Sothys Paris, renowned for its luxurious skincare products. Located on 57th Street, the four-level spa includes ten treatment rooms, a spacious retail area at street level, a makeup area, café, multiple waiting lounges, and a manicure/pedicure salon.

The design prioritized creating an elegant, serene environment that balances privacy with inviting customer spaces. This guided the selection of colors, materials, circulation, and acoustic treatments. A dynamic ceiling feature incorporating moving video enhances the retail experience, adding a contemporary sensory dimension.
