Studio ST Architects is a full-service, award-winning, woman-owned, NYC architecture firm. We design residential, multifamily housing and institutional buildings including new synagogues and places of worship from the ground-up. As NYC architects, our renovations range in scale from community centers, schools and high-end apartments to affordable real-estate developments, including duplex renovations, duplex combinations as well as apartment combinations.


NYC architect, Esther Sperber founded Studio ST Architects in 2003 to focus on sustainable, innovative and responsible design. We strive to combine leading technologies with evolving environmentally-friendly design and production methods, and apply these tools in creative ways. Our firm combines unique expertise in architecture and psychology to design inspiring buildings and renovate spaces that transform our client’s experiences, build deep and inclusive community connections, and create a sense of health and well-being. We pride ourselves on listening carefully to our clients and working collaboratively with them and our partners to create an enjoyable design and construction process.

Our new boutique-style Jones Street multifamily apartment building in Jersey City is nearing completion. We are also working on a number of synagogue architect designs including Ansche Chesed on the Upper West Side in NY and SVAJ in Skokie, IL, which are both slated to complete in 2022. We love designing synagogues and places of worship and find this work to be deeply meaningful and inspiring. Studio ST Architects have completed many institutional buildings including the renovation of the 14th Street Y in 2010 and plans for the Hudson Yard Synagogue, an $8 million renovation project in Manhattan.

Our residential work spans from designing buildings to interior architecture for apartment renovations and combinations. We also work extensively as a duplex architect to combine apartments in NYC, including condominiums and co-ops and convert single family houses. Studio ST is committed to exploring low-budget, green designs as well as high-end residential interiors.

Studio ST’s work has been published in architectural magazines and monographs in North America, Europe, and Asia. In 2019 the SynaCondo project received the AN Best of Design Award honorable mentions. In 2008, Studio ST was selected by Wallpaper Magazine as one of the “World’s 50 Hottest Young Architectural Firms” and the Swell House was selected by Architectural Record as “Best Unbuilt House” for 2008.
