The project would add three new floors on top of an existing two-story building known as Building D. The building is part of the old Philadelphia Warehousing and Cold Storage complex at 40 Spring Garden St, near the Delaware riverfront. County records describe 36 apartments on the upper floors, above a ground-floor commercial space that is now vacant. The records give a maximum height of 84 feet.
A city Historical Commission review packet from April 2026 describes about 44,000 square feet in total. It lists one or two commercial units on the ground floor and loft apartments on the second floor, with new apartments on floors three to five. The packet is for an early "in-concept" review. It asks for feedback on the addition, façade changes, accessible exits and flood-protection upgrades. It also says nearby buildings in the same complex were approved earlier. No news coverage, opposition or named tenants were found.
What it could mean nearby
- 36 new apartments would add housing near the riverfront and Spring Garden area.
- The vacant ground-floor commercial space could be reused for shops or offices, which could bring activity and some jobs.
- The Historical Commission review looks at how a taller addition fits the historic complex.
- The review packet lists flood-protection upgrades, which suggests the site is in a flood-prone area.
Where it stands
The Historical Commission has reviewed the project at the concept stage, and the latest county filing is dated 2026-06-24. Next steps usually include formal design approval, zoning and building permit review, and then construction.
