ORIGIN • STRUCTURE • VALUES
TUCSON250 (T250) was inspired by Alexander Sexsmith, a Tucson transplant and architect whose love of nature and design took him to different locations within the city and surrounding mountains and desert, finding beauty wherever he went. He recognized the vibrancy of this land while witnessing the devastating disregard and elimination of natural landscapes and communities who have stewarded culture and land.
He began envisioning a vibrant community with thriving, healthy buildings and spaces that would benefit future generations - 250 years from now - ensuring they, too, can experience and appreciate the beauty of the land.
T250 is a unique initiative dedicated to transform and enhance natural building processes. We bring together key stakeholders and change-makers to accelerate the creation of healthy built environments in Tucson and beyond. Established through the collaboration of Heart of New Earth LLC (HNE), Sexsmith Architects, and Vali Homes, our goal is to support individuals who steward life and demonstrate co-creative leadership.
Just as seeds need the right conditions to thrive, we recognize that ideas need the right ingredients to succeed. HNE provides the catalytic energy to bring T250 into form. By fall 2025, we plan to achieve 501(c)(3) status and secure funding to hire an executive director and staff. Our vision is to unite Tucson’s residents—professional creatives, visionaries, and doers—to a global network and collaboratively shape the city’s future in harmony with the spirit of the land.
VALUES
SELF-SOVEREIGNTY = ALIGNMENT = RESILIENCE
We believe that everything we need to achieve our goals is available now within each of us.​​ We believe in creating safe, integral spaces that honor the presence invested by creators in enhancing our lives. We cultivate a decentralized model that ensures equitable distribution of the value generated by their contributions.
​
CREATION FROM FLOW STATE
We create from a state of deep listening and curiosity, discerning inspiration from the noise. We ensure value-engineering is never values-engineering.
​
EXPANDING CONSCIOUSNESS
We strive to expand our capacity to love and gain clarity and awareness within our lived experience through engagement. We tune into the collective and inspired ideas, integrating them into decisions and actions that serve the highest good.
​
​CO-CREATING WITH LIFE
We honor the breath of the natural cycle. We listen, rest, act and adapt to enter the path that moves beyond metaphor toward high performance contemporary natural building.
