Built for
Texas architecture.

Glasshaven started in 2019 with one idea: modern homes deserve marketing as considered as their design. We've since become Austin's go-to brokerage for architect-built and design-forward property.

Our story

From one listing to a Texas-wide practice

Founder Maren Ellison spent eight years designing homes before she spent a single day selling them. That background shapes everything at Glasshaven — we represent a property the way an architect would present it: honestly, and with respect for the materials.

Today the team works across Austin, Dallas, and the Hill Country, representing buyers and sellers of contemporary, mid-century, and ranch-modern homes from $900K to $12M.
