Located in the heart of Barrio Viejo, this c.1885 Sonoran-style mud adobe offers a rare expression of Tucson's earliest residential architecture. Spanning 1,288 square feet, the home retains remarkable authenticity with two-foot-thick adobe walls, high ceilings lined with original saguaro rib detail, and early pine floors worn smooth by generations of use. Layered throughout are later artistic touches that feel both intentional and deeply rooted in place--artisan mosaics and the striking, life-size ''water-breathing dragon,'' echo the creative spirit long embedded in Barrio Libre and Barrio Viejo. The interior unfolds with proportions true to the era--intimate, efficient, and adaptable--while the primary bedroom offers a more generous retreat with walk-in closet. Additions introduce polished colored concrete floors alongside a curated mix of architectural salvage: pressed tin ceilings, historic light fixtures, and stained glass windows. These elements act as "house jewelry," thoughtfully layered to reflect the home's evolution over time without compromising the integrity of the original adobe structure. Outdoors, a terraced backyard follows the natural slope of the land, framed by mature vegetation and punctuated by mosaic work that extends the artistic narrative beyond the walls of the home. The setting feels both sculptural and lived-in, a continuation of the property's creative identity. Situated on a corner lot, the property offers off-street parking--an increasingly rare amenity in these historic districts--along with meaningful potential for an accessory dwelling unit. The lot's orientation and access provide flexibility for future expansion while preserving the character and presence of the original home.
