The architect who brought adobe back to the Valley: what his homes are and how to recognize one.
Bill Tull in Paradise Valley (Updated Q4 2026)
By Clayton Wolfe, Partner at The Agency · Published November 2, 2026 · Last updated November 2, 2026
Bill Tull was a Phoenix-area architect and artist, widely credited with reintroducing adobe design to the Greater Phoenix area in the 1970s. He died in 2000. His homes are hand-built adobe in the territorial and Santa Fe traditions, and a Tull house is bought as much as a piece of regional art as a residence. His Paradise Valley work includes custom adobe estates along the golf corridors.
Clayton Wolfe and The Agency Scottsdale are not affiliated with the Bill Tull estate unless stated. Attributions are from public records and published portfolios.
Tull homes trade rarely and are usually marketed on the strength of the attribution. Specific closed sales are being confirmed from the recorded deeds and ARMLS history before they are tabled, so no sold-homes table is shown yet rather than an unverified one. These are scarce; when one comes up it is often a quiet sale.
Hand-built adobe mass. Thick, rounded adobe walls with soft, organic edges rather than crisp corners.
Territorial and Santa Fe detail. Exposed wood lintels, vigas, corbels, and deep-set windows in the New Mexican tradition.
Earth-toned, handcrafted finish. Plaster, clay, wood, and stone in natural desert tones, built by hand rather than machined.
Low, grounded profile. Homes hug the ground and the desert rather than rising for views.
Interior warmth and mass. Thick walls that hold temperature, kiva fireplaces, and intimate, textured rooms.
One-of-a-kind character. Each home is distinct; Tull worked as an artist, so no two are identical.
How to verify attribution. With a deceased architect, confirmation relies on the original permit and plan records, the recorded ownership history, and documented provenance from prior listings or the family. A true Tull adobe has a paper trail; an inspired-by or Tull-style home is a different thing and should be described as such.
What these homes typically require. Adobe is beautiful and demanding. Walls need periodic re-mudding or sealing, roofs and parapets need careful drainage management because water is adobe's enemy, and repairs call for craftspeople who work in earthen materials, not a general contractor. Insurance for a hand-built adobe can be specialized; confirm replacement-cost coverage and that your carrier understands the construction.
How to find current inventory. Tull homes are rare and often sell quietly. For current or upcoming availability, use my Paradise Valley search and reach out directly.

It needs specialized care: re-mudding or sealing, careful water management, and craftspeople who work in earthen materials.
Often not with a standard policy. Confirm replacement-cost coverage with a carrier that understands adobe construction.
