OSSO Architecture, DPC, is a New York City based architecture and interior-design firm founded in 2017 by Margot Otten and Douglas Segulja. We have designed and built projects in New York, New Jersey, Connecticut, Pennsylvania and Texas. We specialize in creating warm, meaningful, and functional environments with clarity of form. Our approach is to work closely with clients to articulate and then realize a shared vision, whether the project is a new construction, an interior renovation, or a piece of custom furniture.

She studied architecture at Parsons School of Design (MArch) and the University of Illinois, Urbana Champagne (BS, Architectural Studies).
