The Ranch Mine is a national award-winning, husband & wife design firm specializing in the design of modern homes in historic and mid-century neighborhoods in Arizona. The majority of our work is comprised of infill houses (new houses on vacant lots) and significant renovations and additions to modest ranch homes, mid-century modern homes and historic properties. Our expertise in combining the character found in older homes and neighborhoods with today's modern desert living uniquely enables us to help you create a one of a kind home that inspires your everyday and contributes to the betterment of your community.

Phoenix, like any other city, has a reputation, a calling card, some easy ways for people to identify it. For a long time the design and development community has been identified as beige, over run with sprawl and speculation, and littered with an obsession for anything perceived as standard or safe. This I.D. did not bring itself into existence. We all hold a stake in the state of our cultural environment. For this reason, we created The Ranch Mine.

Everything we do is grounded in empowering you to be a positive and influential force in the development of your city, and it all starts at home. Home is the foundation of each and every day. If it is strong and inspired, we can carry those qualities into our communities.

In 2009, Cavin Costello received his Masters degree in Architecture and made the drive to Phoenix, Arizona sight unseen, inspired by the complexities and opportunities to be had in the rapidly urbanizing southwest. There he met Claire Costello, then Claire Aton, a Phoenix native looking to make the most of her recent move back home. The two quickly bonded over their ideals of the built environment, how to improve upon it and its ability to influence. Not settling for a hard hit economy to dictate their next move, the duo decided to act. So, they bought a fixer upper and experienced first hand the trials and tribulations of redesign.

The two continued paving their own path developing the First Phoenix Green Construction Code project, designing for visionary real estate developers, and creating inspired homes for unique homeowners like you.
