What is Infill Development?
Infill development is the process of building new housing, commercial buildings, or amenities on vacant or underutilized land within existing urban areas.
Why Infill Development Matters in Real Estate
In Canadian urban planning, infill development supports smart growth by making efficient use of existing infrastructure and reducing urban sprawl.
Key benefits:
- Revitalizes older neighbourhoods
- Supports transit-oriented communities
- Reduces pressure on agricultural or natural lands
Understanding infill development helps municipalities, developers, and residents balance growth and community character.
Example of Infill Development in Action
The city encouraged infill development by offering incentives for building new townhouses on a former industrial site.
