About Us

Sustainaprise is a practice rethinking how we build, use, and share space by developing new ownership models, reusing what’s overlooked, and creating more inclusive ways to live and work.

We focus on creating attainable housing and alternative ownership pathways through co-living, adaptive reuse, and modular development, helping to lower barriers to participation in real estate. At the same time, we partner with organizations by offering outsourced workplace experience staff, workplace strategy, and sustainable operations advisory.

Whether we’re supporting the creation of something new or helping to evolve how people engage with existing spaces, our work is grounded in the belief that real estate should better serve both people and the planet.
