Features
The first floor welcomes you with a covered front porch

The first floor welcomes you with a covered front porch (19′-2″ x 4′-4″), creating an inviting entry transition into the home. Inside, the open-concept living area seamlessly blends the kitchen, dining, and living room, making the space feel larger and more connected. The kitchen is positioned along one wall with ample counter space, a full-size range, and a double-basin sink, complemented by a central island with seating for casual dining or entertaining. Adjacent to the kitchen, the living area comfortably accommodates a full-size sofa and seating arrangement, while natural light enhances the openness of the space. A full bathroom is conveniently located near the staircase, optimizing accessibility without interrupting the main living flow. The centrally located staircase efficiently connects both levels while minimizing wasted square footage.
Upstairs, the second floor is dedicated to privacy and comfort. The primary bedroom (12′-8″ x 9′-11″) offers generous proportions for a queen-sized bed and additional furnishings. A walk-in closet (5′-0″ x 6′-5″) provides ample storage, while the adjacent bathroom features a shower, toilet, and vanity in a compact yet functional layout. A unique highlight of this level is the flexible nook (8′-9″ x 7′-9″), which can serve as a home office, reading area, or even a small nursery—adding versatility to the design.
Alamo Vista Plan offers efficiency & balance
Architecturally, this ADU aligns well with contemporary aesthetics, featuring clean lines and efficient vertical stacking of plumbing and mechanical systems for cost-effective construction.

Overall, this ADU balances modern livability, efficient design, and flexible use, making it an excellent solution for homeowners looking to expand property value while maintaining a stylish, functional environment.
