One Logan Square, Office skyscraper in Logan Square, Philadelphia, Pennsylvania.
One Logan Square is an office tower in Philadelphia with 31 floors rising prominently in the Logan Square neighborhood. The building features a modern design combining glass and steel, with office space, restaurants, fitness facilities, and conference areas for its tenants.
Construction of the tower began in 1979 and required special zoning arrangements to meet city height restrictions. A low-rise hotel component was integrated into the design as part of this regulatory accommodation.
Morgan Lewis & Bockius law firm secured an equity stake in the building through their initial lease agreement, establishing a new model for tenant partnerships.
The building sits conveniently close to public transportation, making it easy to reach from different parts of the city. The surrounding area offers various dining and café options within walking distance.
The development cost of 120 million dollars in 1983 represented one of the largest commercial real estate investments in Philadelphia during that period.
