3815 Callahan Avenue This exquisite custom estate sits on an oversized corner lot and presents a private sanctuary with abundant possibilities. The thoughtfully designed single-story floorplan includes two lavish primary suites at opposite ends plus two spacious additional bedrooms, while the 693 square foot guest house includes a living room, kitchen and separate bedroom with en-suite bathroom. Fifteen French doors act as walls of glass, bathing the wood beams of the grand vaulted ceiling and custom chef's kitchen in golden light. Granite counters, R/O filtered water, stainless appliances and a walk-in pantry complete the entertainer's kitchen. The dual primary retreats pamper with custom closets, tile floors and upgraded baths. Outdoors, the half-circle driveway with dual electric gates leads to separate gated RV parking. The expansive yard also features a charming courtyard, volleyball court, gazebo and watch tower, yet still offers an abundance of space to customize your ultimate private refuge.
