We are often asked how we came up with our company name, The Ranch Mine. Before we formed our company back in 2010, we spent 7 months traveling around Arizona, exploring the rich history of our state. During these trips, a common thread started to emerge: the pioneer spirit. Everywhere we went we heard stories and saw manifestations of the driven, impassioned people, such as ranchers and miners, who were willing to endure hardship in search of a better life. This spirit is still alive and well today and serves as inspiration to design spaces that afford us the opportunity to imagine what’s beyond what we see in the present so we can strive for new experiences.
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. He had not yet been a full day in Phoenix when he met Claire, 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 a major renovation.
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. Cavin and Claire have continued to push the envelope in designing for the pioneer spirit which has won them the 2019 HGTV Designer of the Year for their ‘Red Rocks’ project, a 2015 National American Institute of Architects contest that named them the “Future of Architecture”, landed them features on the NBC Today Show and with HGTV, and had their work published in numerous books and publications on 6 continents around the world.
Behind every project we take on is a highly-skilled team. Following suit, our team is composed of adventurers who each possess the pioneer spirit and strive to break the boundaries of conventional thinking.
Cavin Costello is the son of a civil engineer who endeavored to build his own house in rural Connecticut. It is safe to say that this exposure to building systems mixed with a “go get ’em” attitude laid the foundation for Cavin’s future. Cavin pursued his childhood passion at Northeastern University from which he earned a Bachelor of Science in Architecture and a Master of Architecture degree, graduating Summa Cum Laude. During his schooling he was able to study in and call Florence, Italy home, using that time to explore the country, building his appreciation for history and how culture and context affects the built environment. His enthusiasm for adventure led him to Phoenix, Arizona where he has become a prominent figure in the community. To date, Cavin has designed over 175 projects around the United States and the world, winning multiple national and local awards, including HGTV’s “Designer of the Year” in 2019 and “The Future of Architecture” award from the American Institute of Architects in 2015. Cavin is a licensed Architect in Arizona, Tennessee, Montana, Colorado and North Carolina.
Claire Costello is a native Phoenician who received unique exposure to rambling ranches, mid-century modern and desert architecture. Claire was young when she was asked to pick up a shovel and do some dirty work at her aunt and uncles in Tucson. This “dirty work” was digging dirt to build the first rammed earth house Claire had ever known of. Leaving the desert behind, Claire ventured to the University of Colorado at Boulder where she received concurrent Bachelor of Science degrees in English and Communication. Her time away from Arizona led Claire to travel the world, fueling a desire to make real change and igniting a belief in the power of action. Upon returning to her hometown, Claire sought to make a familiar place new, exciting and her own. Emboldened with an entrepreneurial spirit, Claire is committed to reclaiming her hometown of Phoenix one home at a time. Today, Claire embraces a hands-on approach to design and development and works toward shaping a more vibrant community.
Growing up in Arizona, Rachel developed a robust appreciation for the joys and challenges of desert-dwelling. After years of traveling to different states and countries, learning from various cultures and people, she returned to Phoenix in order to employ that knowledge while engaging with the built environment. This, in addition to her background in both architecture and engineering, has allowed Rachel to approach design with a unique perspective that she continues to develop and apply to every aspect of a project.
Rachel joined The Ranch Mine in 2018 shortly after receiving her Masters of Architecture from UCLA. She also earned her bachelor’s degree in Structural Engineering from Brown University. She is a registered architect in the state of Arizona.
Geoff grew up in Georgia during a time when houses were being built by the hundreds. Walking through those neighborhoods during construction is when he fell in love with Architecture. It was also during this time that he was first introduced to the desert southwest during a backpacking trip to New Mexico.
After undergrad and living in Europe, Geoff moved to Oregon for graduate school for a change of pace and scenery. It's here that his passion for mountain biking, trail building, and architecture began to really formulate. He spent a number of years working on projects of all scales and typologies including; digital fabrication, creative office renovations, performing arts centers, multi-family residential, and various mass timber projects. During this time with Lever Architecture, he was able to focus on his original love of residential architecture, working on a number of residential projects over a few years.
In an attempt to escape the pacific northwest winter, he found himself in Phoenix for a sunny vacation and it's there that his childhood memories of the desert southwest resurfaced and he knew he needed to find his way back there professionally.
Geoff holds a BS in Architecture from Georgia Tech and a MArch from The University of Oregon.
Nicole was raised in Southern Louisiana where art classes, folders of unbuilt treehouse designs and a deep curiosity for the region's unique blend of culture, architecture, music, and cuisine were her gateways into the creative world. Hurricane Katrina expanded her understanding of the boundless powers of nature over the built environment, influencing her choice to pursue an architectural education.
After graduating with a combination BS and MArch from Tulane University, she sought out a new and entirely different locale by moving to Phoenix. She spent over 6 years working in commercial architecture on a varied collection of project types and scales, including multifamily residential, municipal, master planning, adaptive reuse, and behavioral health care.
Nicole enjoys reading, cooking, and exploring, and has gotten to know the desert intimately through camping, offroading, hiking, and paddleboarding. She joined The Ranch Mine in 2022 and is a registered architect in the state of Arizona.
Benjamin was born and raised in the United Kingdom, where he earned a Bachelor of Architecture at the University of Lincoln. Ben went on to work with a variety of successful architects in the UK whilst continuing further studies in architecture. His love of travel ultimately led him to the United States and a move to Arizona in 2015.
Having gained a wide experience in high end residential and commercial projects, both in the US and Europe, his passion for exceptional design continued him on a path to The Ranch Mine in October 2018. Specializing in 3D visualization and representation he became an integral part of any project.
Originally from the gulf coast of Texas, Morgan grew up wanting to pursue a career in medicine. After service in the Air Force and a bachelor’s in biology, she realized the medical field was perhaps not the right fit. Shortly thereafter, she visited a roommate’s architecture studio, and the rest is history.
Graduating with a MArch from UTArlington, she left Texas for Los Angeles. Beginning her professional architecture career in LA, she was able to work on a varied selection of projects both national and international. For the last 10 years, she has been back in Dallas, working on sports arenas, musuems, and NFL Stadia with some residential scattered in between. Her passion is residential architecture, and she is pleased to be working with homeowners again since joining The Ranch Mine in 2022. In her free time, she enjoys anything outside, renovating her home & yard, good food & music, traveling, and probably every cat she has ever met. Morgan is a licensed architect and registered interior designer in Texas.
Stefan grew up in Reno, NV, surrounded by the diverse landscapes of the high desert. Spending summers and winters engaging in outdoor activities at Lake Tahoe, he developed a deep appreciation for the environment. During a high school internship program he discovered his passion for designing living spaces that coexist with nature, drawn by the intersection of rational and artistic potential and the opportunity to influence people's lives.
In college he expanded his knowledge of architectural history in Florence and honed his skills by apprenticing for a professor of architecture in Hamburg. Graduating from the Syracuse School of Architecture, Stefan earned multiple awards for his thesis project on diplomatic structures.
With a decade of experience under his belt, Stefan has worked on large and small projects at every phase of construction. Single family homes, apartment buildings, mixed-use towers, restaurants, and commercial office spaces to name a few. He enjoys navigating the complex challenges of designing and constructing architecture as a trusted advisor of his clients and an enthusiastic partner to the builders he's collaborated with.
Stefan joined the Ranch Mine in 2023. He is licensed in Arizona and Washington, a LEED Green Associate, and certified by the National Council of Architectural Registration Boards. Currently residing in Tucson, AZ.
