The project at 2800 Diamond Street in Strawberry Mansion is a new four-story apartment building with 46 homes. County records say it will have a green roof, a roof deck, two small rooftop stair structures (pilot houses) and an accessory parking garage.

A November 2024 news report says building permits have been issued. It puts the building at about 46,713 square feet. The site is a fenced vacant lot where a church once stood. The report describes the exterior as gray brick on the ground floor with siding on the upper floors.

No opposition, zoning hearing or future tenant details turned up. Earlier coverage of a 33-unit, three-story plan at a similar address (2800-24 Diamond Street) appears to be an earlier version, but the sources do not confirm that.

What it could mean nearby

Where it stands

Permits appear to have been issued by November 2024, so the project has likely cleared city review and can start construction. Next steps are usually construction inspections and then a certificate of occupancy before tenants move in. No construction progress was found.

Want to weigh in? Permits appear to be issued already, so no further approval is known. Residents can contact their City Council district office or the Philadelphia Department of Licenses and Inspections with questions.

Who's behind it

Design Pro Development · A news article credits this company for the project's renderings. The county filing instead lists 2023 N 29th St LLC and Axis Construction Management LLC, and the sources do not say how the three companies are related.
