Philadelphia’s Newest Waterfront Neighborhood

Ensemble is creating an enduring legacy at the Navy Yard, a legacy comprised of a collection of projects which are enriching and connecting the fabric of Philadelphia.


Active on the campus since 2010, Ensemble has committed more than $500M to a portfolio of assets that total more than one million square feet of Class A office space, state of the art laboratory and GMP manufacturing buildings, and a hotel, all with an eye on stewarding the development of public lands, for public good, for generations to come.
In 2020, Ensemble partnered with Mosaic Development Partners, responding to and winning the exclusive development rights to an additional 109 acres at the Navy Yard. This is a $4.8B, 15-year program that includes the development of life science, corporate, residential, hospitality and retail properties – what amounts to the creation of Philadelphia’s newest waterfront neighborhood.


The Ensemble/Mosaic team is harnessing Ensemble’s considerable investment in its existing commercial properties and continuing to transform the Navy Yard into a nationally recognized place – one of the most successful redevelopment projects in the nation.


This vision, based on the 2022 Comprehensive Plan which was shepherded by Ensemble/Mosaic in 2022, is unlocking the full potential of this distinctive place. The plan calls for more than 2.5M square feet of life science and office, 4,000 residential units, dynamic neighborhood retail, new hotels, and thoughtful open and gathering spaces.
