Plan Overview

Small Footprint, Real Livability

This 25 by 12 studio casita keeps the plan simple, bright, and practical. The open living and kitchen area does the heavy lifting, giving the space room for seating, dining, flexible sleeping, or a work-from-home setup without wasting square footage on hallways.

The full bath anchors one end of the plan, while the kitchenette and storage run along the main wall for an efficient daily-use layout. A 12 foot sliding glass door brings in natural light and helps the studio connect directly to a patio, courtyard, or backyard retreat.

Build Quality

Designed For Arizona
