It may seem counter-intuitive, but co-op and condo boards can save money by doing major building repair projects back-to-back. Leon Geoxavier, senior project manager at Howard Zimmerman Architects, and Evan Petkanas, president of STONE Engineering & Architecture, are here to tell us how one building facing both a roof replacement and facade repairs did just that. The price tag was hefty, but smaller than if the projects had been done separately. Leon Geoxavier and Evan Petkanas are interviewed by Bill Morris for Habitat Magazine.
