Converting office buildings to residential uses has been a hot topic around Philadelphia, and across the country, given the softening office sector as remote and hybrid work remain strong. Alterra Property Group, a prominent Philadelphia real estate development and management company, deemed 1701 Market Street in the heart of Center City as a prime candidate for such a conversion. The design vision by NORR and Eileen Tognini Design is to transform the 18-story high-rise building into a modern Class A residential mixed-use complex focusing on wellness.
Built in 1957, the exterior design preserves portions of the original Indiana limestone. To bring a tripartite facade and vertical expression to the horizontal tower, limestone strips were cut at the floor line allowing the incorporation of taller windows. A channel shape made of metal panels will lead up the façade to the sky frame which will capture unique views of the city.
The project is scheduled to open in June 2025 and DAG looks forward to welcoming the development, design, engineering, and construction team to discuss the details of the project, share some of the lessons learned during design and construction, and reflect on the unique challenges inherent in this type of office to residential conversion.
This event will be held at the Center for DesignPhiladelphia, 1218 Arch Street, Philadelphia PA 19107.
Registration is not required for in-person events, however it is helpful for our planning. Light refreshments will be served.
