UNLOCKING THE POWER OF TOGETHER

Flowing through the heart of Austin, the Colorado River—the sixth river south of the Red—has long been a source of beauty, sustainability, and vitality for the city and its residents. Inspired by this steady and life-giving force, Sixthriver was born in 1994, named after the river that embodies the attributes we strive to emulate: strength, consistency, and the power to bring people together.

Founded by a group of architects and designers deeply connected to Austin’s culture and heritage, Sixthriver has grown from a local design firm to a trusted name across the nation. Our portfolio includes over 50 million square feet of built environments, spanning office buildings, mixed-use developments, student housing, corporate interiors, and hospitality projects.

As a woman-owned and led firm, we are proud to hold HUB, WBE, and DBE certifications. With 81% of our team actively engaged at every level of design and execution, we champion collaboration, equity, and innovation in all we do.

From our roots in Austin to projects in over 30 states and 75 cities, Sixthriver remains dedicated to creating spaces that inspire, connect, and serve communities. Whether tackling large-scale developments or smaller, intimate projects, we approach every challenge with the same care, sustainability, and attention to detail that reflects our clients' visions.

At Sixthriver, the story of the Colorado River is woven into our identity. Like the river, we aim to provide vitality and vibrancy—crafting designs that leave a lasting impact for generations to come.
