Debra Heller Stein, a nationally recognized land-use strategist, “NIMBY-ism” expert and advocate for affordable housing and smart growth, died on July 30 in California of complications related to a rare neurologicial disease. She was 48. Stein, an attorney, was co-founder and president of GCA Strategies Inc., a San Francisco-based consulting firm that specializes in building community and political support for land-use projects. She also collaborated professionally with her husband, Jeffrey Heller, president and CEO of Heller Manus Architects, San Francisco. That firm recently was chosen to lead design and construction of urban redevelopment in Guangzhou, China.Projects include the 1970 renovation of Whig Hall at Princeton University, Princeton, N.J., the 1992 addition to Frank Lloyd Wright’s Guggenheim Museum in Manhattan and the 2007 renovation and addition to the Art and Architecture Building at Yale University, New Haven, Conn. On those projects, Gwathmey and Siegel “were given the task of contending with some of the most complex architectural precedents of the 20th century,” says Architectural Record magazine, sister publication to ENR. Pending an agreement with the executors of Gwathmey’s estate, Siegel says he intends to continue the practice’s work. Among other projects, the firm is designing a building for the U.S. Mission to the United Nations. Gwathmey’s association with noted architects Peter Eisenman, Michael Graves, John Hejduk and Richard Meier, known as The New York Five, was another career highlight. Gwathmey Siegel noted its founder’s “dedication, prodigious talent, love of architecture, rigorous standards and enduring commitment to Modernism.” A company spokesman says Gwathmey’s family has not yet finalized details of his upcoming memorial.
