Georgis & Mirgorodsky is an architecture and interior design firm in New York City with a design office in La Jolla, California. Originally established as William T. Georgis Architect in 1992, Ilya Mirgorodsky was made a partner in 2017, when a new firm was established.

Georgis & Mirgorodsky works collaboratively with clients in a variety of styles—the past and present and an obsession with detail and craft inform all projects.

The firm has designed and completed numerous residential, institutional, and commercial projects in the United States, Mexico and the Caribbean. These include new houses in Southampton, New York, the Bahamas, Montana, La Jolla, California, Aspen and New York City, the Tiffany Gallery at the Museum of the City of New York, The Grill and The Pool restaurants at New York’s Seagram Building, interiors of a Gulfstream G650 jet, and the renovation of the public spaces of the landmarked Lever House in New York City. In addition, the firm has completed the design of Manhattan condominium projects at 350 West Broadway, 530 Park Avenue and 100 East 53rd Street. Georgis & Mirgorodsky has also completed designs for the Gramercy Park Hotel and a line of furniture for Maison Gerard, New York.

A monograph of the firm’s work Make It Fabulous: The Architecture and Designs of William T. Georgis was published by The Monacelli Press in 2013. The firm has been included in the AD 100, Architectural Digest’s international guide to the top one hundred architects and interior designers since 1996.
