1-Bed Modern Cottage ADU with Vaulted Living — 594 Sq Ft
This sleek, one-bedroom cottage spans approximately 594 heated square feet, and is designed with a modern aesthetic and efficient layout. With a vaulted living area, full bath, and an eight-foot-deep front porch adding about 180 sq ft of outdoor space, it’s ideal as a guest house, rental unit, or compact primary dwelling.
Exterior & Curb Appeal
The exterior presents clean lines and minimalist structure with a gently pitched roof and contemporary finish materials. At roughly 22′-10″ wide by 34′ deep, it has an approachable footprint that fits well on smaller lots or as a backyard ADU. The front porch creates inviting curb appeal, offering sheltered outdoor seating and a visual connection to the street.
2D Floor Plan & Interior Layout
Entry from the front porch leads directly into the open living space, where the ceiling vaults to about 13′ high, making the area feel much larger than the square footage would suggest. The living zone flows into the kitchen, which is efficiently placed along one wall to maximize layout flexibility. Toward the rear lies the bedroom and full bathroom. Wall-to-wall design keeps circulation minimal and functional.
Bedroom & Bathroom
The single bedroom is tucked quietly at the back of the home, creating privacy while still staying connected to the main space. The adjacent full bathroom serves both the bedroom and living area, making the plan functional whether used for one occupant or guests. All amenities are included in the compact footprint without sacrificing comfort.
Porch & Outdoor Living
The front porch spans 8 feet deep and adds approximately 180 square feet of usable outdoor living space. This generous porch invites outdoor lounging, greeting guests, or simply relaxing in the shade. It effectively extends the home’s livability outdoors and enhances its connection with the surroundings.
Structure & Specifications
The walls are framed in 2×6 construction, supporting enhanced insulation and structural durability. The roof is stick-framed with a low-profile pitch—about 1:12—which gives the home a clean modern silhouette. The max ridge height is around 14 feet. Ceilings are about 10′-6″ on the main floor, with vaulted peaks near 13′ in the living/kitchen zone. The foundation is a monolithic slab.
Lifestyle & Cost
This modern ADU is perfectly sized for minimalist living or a comfortable guest dwelling. The vaulted ceiling adds a sense of spaciousness, the efficient plan captures every square foot, and the front porch makes outdoor living part of the experience. It’s ideal for singles, couples, or as an income-producing unit.
In the U.S., an estimated build cost for a home of this size and layout typically ranges between $120,000 and $180,000 USD, depending on finishes, region, site conditions, and builder. With thoughtful design and quality detailing, this cottage delivers style, comfort, and efficiency in a compact form.
