Our innovative approaches to sustainability are recognized throughout the multi-family industry and our award-winning green projects demonstrate our commitment to excellence – and to the planet.  During the past three decades in Mid-Atlantic and the Northeast, we have transformed 28 historic properties into more than 3,100 units of mixed income housing in mixed use communities and completed the largest deep energy retrofit of an existing affordable housing development in the nation, as well as the mixed income housing conversion of an historic building that is now Boston’s only mid-rise LEED Platinum certified project. We are in the midst of renovating the iconic, 12-story Sibley Building in downtown Rochester for commercial and academic uses, as well as market rate and affordable housing. To learn more about Sibley Square click here.
