FosterArchitecture,  Jonathan S Foster is a full service architecture firm specializing in solving space and organization problems with an aesthetic discipline. Jonathan Foster has developed a "collaborative design process" where clients and architect are able to design accurately together in 3-Dimensions on a computer together. This can be demonstrated in large meetings where everyone in attendance is able to understand and sign off on the issues at the same time. This leads to clear thinking about design issues and an appreciation of the "right" solution by all concerned.

Jonathan S. Foster, has had a private practice in Architecture since 1984 in New York City. Mr. Foster, having been in other businesses before going into architecture understands that key is to be able to articulate a hierarchy of values and functions, and design with those priorities. This leads to the architect being able to solve real problems which concern users of the final design.

This approach to design has developed many satisfied and continuing clients such as: Computer Science Corporation, SEI Investments, Yves Saint-Laurent of America, and others. Grace Church in New York, where we recently completed a major renovation of its historic Parish House is a recent client.

Mr.. Foster previously worked with Skidmore Owings and Merrill, and Redroof Design in Job Captain and Project Architect positions. Articles about Jonathan Foster and his work have appeared in such publication as: The New York Times and the San Francisco Chronicle since 1982.

Jonathan earned an AB in Art and Economics from Allegheny College (1967) and a Master of Architecture from Harvard University (1980) where he was a University Fellow. He has since taught seminars and courses at the Cooper-Hewitt Museum and Harvard Graduate School of Design in addition to design critic at other institutions. He has  completed 12 years as Chairman of Landmarks for the New York Community Board No.5 covering central Manhattan.
