The full picture AI research · Nov 1, 2026
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
- 46 new apartments would add housing on a lot that is vacant now.
- The accessory parking garage suggests some parking will be on site. The records do not give the number of spaces or say how it would affect street traffic.
- The green roof and roof deck are private building features. They are not public open space.
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.
- Nov 18, 2024 News report says permits were issued for the 46-unit building
- Nov 13, 2024 Latest county filing
- Jun 2021 Earlier news report of permits for a 33-unit, three-story building at 2800-24 Diamond Street, which may be a prior plan
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.
