Jeff Sydness, the founder of Sydness Architects, has created an international practice which specializes in both commercial and institutional work, ranging from high-rise residential and office towers to a master plan for a university in India and commercial interiors. Known for his ability to combine creative design solutions with the realities of large scale development, he brings over 30 years of design experience in corporate, commercial, hospitality and residential buildings to a wide range of U.S. and international clients.

Mr. Sydness founded Sydness Architects in 1996, after winning an invited international design competition for the Shanghai St. Regis Hotel. He built steadily on that success, with commissions for major projects in some of the fastest growing areas of Asia and the U.S. They include The Alexander, a 25 story residential tower in New York City; a mixed-use complex proposed in Cairo, Egypt; the repositioning of One Light Street in Philadelphia; a planned community for Phoenix, Arizona; and residential towers in St. Petersburg and Tampa, Florida.

Previously, Mr. Sydness was a partner with Johnson/Burgee Architects, a leading international architectural firm of the 1980’s and 90’s. Working closely with Philip Johnson and John Burgee, many of the buildings he designed have become significant landmarks, including 500 Boylston Street in Boston; Puerta de Europa in Madrid, Spain; and the Conrad International Hotel in Singapore. He received his BA degree from Principia College and his Master of Architecture degree from the University of Minnesota.
