Keystone Property Group, the owner of the One Belmont Avenue property in Bala Cynwyd, has proposed redeveloping part of the site. County records describe three new buildings totaling about 17,115 square feet, a new public gathering space, streetscape and landscape improvements, and an overflow parking structure. The records classify the project as retail and commercial.
The whole property covers about 6.76 acres. A 2016 magazine report described it as an office property at Belmont and City Avenues with a large surface parking lot. The same report said the owner was considering mixed-use development on that lot.
No recent news, township agendas or minutes specific to this proposal were found. Tenants, approvals and opposition are unknown.
What it could mean nearby
- The overflow parking structure suggests the plans aim to handle parking demand on site. The records give no traffic study results.
- The new public gathering space and streetscape work could add walkable open space near City Avenue.
- Three small commercial buildings could bring shops or services and some jobs. The tenants are not known.
Where it stands
A filing was made with the county on 2025-08-22. No approval decision was found. Township review usually comes next, covering the planning commission and then the elected commissioners for land development approval.
