Solving housing affordability
by building on existing sites
Turning what's there into what's next
WHAT
WE DO
Existing Plus specializes in adding new units to sites with existing multifamily or commercial buildings. We unlock hidden value in underutilized land—whether it's a parking lot, garage, excess lot space, or rooftop potential—by building high-quality new units that enhance both the property and its long-term performance. Our approach is efficient, infill-driven, and tailored to the realities of existing land use. From feasibility through construction, we help property owners grow their portfolios without starting from scratch.

WHY
EXISTING SITES?
Existing sites have the benefit of being easier to build on because of a number of critical factors which can slow down construction on raw land.

DOING DEVELOPMENT
DIFFERENTLY
We’re rethinking how infill development gets done. While large developers chase big projects, the “missing middle” — small-to-mid-scale multifamily housing — is often overlooked. We focus on these critical, underserved spaces, bringing a more hands-on, adaptive approach that’s better suited to the scale and complexity of infill sites.
