The Best Green Architects in Philadelphia, Pennsylvania

10 Min Read



As one of the oldest municipalities in the country, Philadelphia is home to a lot of old but very important buildings. Its long list of national historic landmarks—67 to be exact—includes the meeting place of the founding fathers of the United States. While history is a source of pride to Philadelphians, there is more to the city than meets the eye.

Philly is a thriving economic center and one of the most relevant educational hubs in the country. The city has been going through an urban transformation for the past few years. And with urbanization comes the call for conservation, both historically and sustainably. The city of brotherly love is now taking steps to go green as it joins The Nature Conservancy’s Urban Conservation Initiative. This will put the city on the road to becoming one of the greenest cities in America.

The architects in this list are some of the best contributors to Philly’s green initiative. These 10 green architects are the best in sustainable design in the region and they were selected based on their impressive portfolios and inspiring commitment to green building.
