Infilladelphia: A Template for Urban Infill Development

We are working on a prototype for urban infill development that focuses on the planning and design process at the neighborhood and block scale.

Infilladelphia is an award-winning competition proposal that tests out this decentralized development model in the Mantua-Belmont neighborhood of Philadelphia.

In areas such as Mantua-Belmont, where urban vacancy and blight exists in close proximity to high land values and urban cores, gentrification is a risk. Development in similar areas commonly results in multi-parcel buildings that are significantly larger in scale than the existing housing stock and escalating property values that challenge the local community. Total neighborhood health is a first principle for Infilladelphia. Social well-being, physical well-being, and economic well-being are seen as key components in a continuous feedback loop to sustain long-term community health.


Infilladelphia proposes a neighborhood development methodology that incorporates tactical interventions into a long range planning process, uses new data resources to optimize key community programming, creates low-rise housing prototypes to facilitate parcel-by-parcel development, and engages a financing model that lowers the bar to home ownership by allowing community stakeholders to become partial owners and financial stakeholders as their neighborhood changes.


Supernormal is collaborating with a cross-disciplinary team of finance, design, planning and real estate professionals to move this proposal from idea to reality. Infilladelphia is the first in a string of tests to build out a replicable urban development template for changing communities with high levels of infill development potential.

We are actively seeking partners for this effort and are considering neighborhoods in Pittsburgh, PA and Holyoke, MA as test cases for an executed prototype.
