Exterior & Curb Appeal
The exterior of this ADU showcases a clean, contemporary look with subtle cottage influences. Its straightforward rectangular shape and sloped roofline create a balanced profile that feels both modern and timeless.

2D Floor Plan & Interior Layout
Inside, the thoughtful floor plan maximizes usability without sacrificing flow. The front door opens directly into a bright living area that connects seamlessly to the kitchen and dining space. The open-concept arrangement makes the home feel larger than its square footage, with high ceilings and wide windows adding to the airy atmosphere. The kitchen features efficient counter space, a pantry area, and room for full-size appliances—ideal for everyday cooking and entertaining in a compact home.
The two bedrooms are positioned along one side of the home for privacy. The larger primary bedroom includes a generous closet and direct access to the shared bathroom, while the second bedroom can function as a guest room, office, or creative space. Between them sits the bathroom, conveniently located for accessibility and designed with modern fixtures and clean lines. Every room benefits from natural light, giving the home a bright and cheerful interior feel.
Porch & Outdoor Living
Although small in size, the front stoop serves as a cozy transition between the outdoors and indoors. It’s large enough for a small chair or decorative plants, adding curbside warmth. For those wanting more outdoor living, the addition of a side patio, small deck, or pergola-covered seating area can extend the living experience beautifully. The home’s simple exterior design makes such enhancements easy to integrate, giving homeowners flexibility for their lifestyle needs.
