Keystone develops and invests in commercial properties that inspire and unlock potential to succeed. We believe dynamic buildings attract dynamic people. And when dynamic people work together, companies thrive. There's a fundamental change in the way people think about work. The spaces we occupy need to reflect that.

From collaborative facilities that help spark your next big idea to integrated technology that lets you share it from anywhere, we’re redefining properties so that every detail is designed to bring people together and give them the space to push boundaries. By staying a step ahead of the way work is changing, we can unlock your potential to succeed.

As Unusual

When you sign a lease with Keystone, we’re more than tenant and landlord—we’re partners. We understand what your business needs are when you first move in, as you grow into the space and when you’re ready to take on something bigger. We make sure your building is working its hardest to help you succeed, and we give you the support structure and flexibility to flourish.

Since 1991, we’ve been creating vibrant and productive communities out of commercial real estate.

of Success

Since 1991, we’ve been creating vibrant and productive communities out of commercial real estate. We acquire, develop, lease and manage real estate, working with office, flex and industrial spaces in major markets throughout the United States. We also work with investors, private equity real estate funds and joint venture partners, overseeing the management, financing, securitization and disposition of all fund assets on their behalf.

Most commercial real estate was built before any of the major shifts in the workplace began to take root. That means today, we have the opportunity to take those buildings and completely reimagine them, integrating technology and creating spaces where wellness and community are a priority.
