Roman and Williams Buildings and Interiors is the New York City-based design studio of principals Robin Standefer and Stephen Alesch.

Roman and Williams is, first and foremost, focused on people and their experiences of a space. The firm, named after Standefer and Alesch's grandfathers, was founded in 2002. Having worked together for a decade designing sets for significant Hollywood films, the pair took their first steps away from film when Ben Stiller asked them to design a home for him in Los Angeles.

They believe that the story of a space is just as important as the design and the objects that go into it – it all plays into the experience. As a firm, they are never focused on a definitive style from any era, instead choosing to strip things down to their essence. They focus on a vernacular language, because vernacular is beyond design. They are known for their contradictions and use of layers and eclecticism. Roman and Williams is interested in spaces and objects that people can truly use and things that genuinely last, and the firm's work is devoted to rebelling against disposability and the common stereotypes of what it means to be “modern” today.

Roman and Williams has also launched a product-design division and is designing several product and furniture lines, which range from the highly refined to the more accessible and reflect all aspects of the Roman and Williams’ psyche. Such work includes the R.W. Atlas line for Waterworks, released September 2012 and Roman and Williams + MatterMade, a line of custom light fixtures, accent tables, and a reader chair designed in collaboration with New York deign gallery Matter, premiered at ICFF in May 2013. The line was praised by the New York Times for having “laserlike attention to details.” They have also collaborated with Ace Hotel on a hotel project in Manhattan and a partnership with world renowned luxury French company Lalique.
