    330 sq. ft. ADU Floor Plans

    An accessory dwelling unit with small square footage is for homeowners who live alone or as a couple, have a grown-up kid, or have aging parents in need of their own separate space. A 330 square feet apartment is a modern solution for an affordable housing problem, a potential boost to your monthly income, or just extra new space on your site.

    330 square feet ADU by A+ Construction & Remodeling is a pre-designed project we offer to those seeking a compact ADU house equipped with all amenities.

    ADU of 330 sq. ft.: Upgrade Your Property

    How to determine that you need an ADU construction? If you’re a homeowner who lacks living space in the main house but cannot afford to expand the residential area by buying a new house, ADU development is for you.

    Our 330 square feet ADU model can be helpful for California house owners in the following cases:

    1. You need a unit to rent out and generate rental income;
    2. You want to increase the value of your property before resale;
    3. You need a dedicated space nearby for your grown children or retired seniors.

    Traditional ADU projects may serve a variety of purposes, including provision of space for business endeavors, home office work, or creative activities. Our 330 square feet ADU can also provide such opportunities, but for the most part it focuses on creating comfortable living space within a limited square footage.

    ADU of 330 sq. ft. Features

    This one-bedroom ADU consists of three separated areas: bedroom area, bathroom area, and combined area including kitchen and living room. The joint area has an L shape and comprises 159 sq. ft., providing room for free movement in the conditions of restricted space. On the other hand, a separated bedroom with a double bed offers enough seclusion and intimacy that a small ADU may sometimes lack.

    A+ 330 square feet ADU model offers such benefits as:

    • reduced energy bills, easier maintenance, and construction costs;
    • strategically organized rooms and mindfully located furniture;
    • cohesive and modern-style solutions;
    • all electrical appliances and energy-efficient appliances and fixtures;
    • full-size bathtub and kitchen appliances;
    • sturdy and eco-friendly materials.

    Efficient Layout

    Designing the most effective layout is not only a matter of aesthetics. When it comes to small units, we can create a sense of continuity and flow of movement within the space, visually enlarging a limited area. Also, by putting large furniture in the corner, we generate more space closer to the center of the ADU, thereby improving both functionality and visual spaciousness. A closet placed in a convex niche contributes to increasing storage space while allowing you to make the most of that peculiar area.

    Fashionable Interior

    We’re glad to display an example of modern and contemporary style in our 330 square feet ADU model, reflecting in clean lines and neutral walls and doors. Decor in the form of padded and wattled elements adds warmth and homeyness to the otherwise strict modern design. The warm tones of the wooden flooring seamlessly extend across each room.

    Quality Materials

    We use solid wood for cabinetry and choose rot- and water-resistance surfaces to ensure your ADU’s longevity and usability. We also opt for more effective insulation to prevent extensive heating and cooling.

    Economy of Resources

    Our commitment to detail extends to the selection of energy-efficient appliances, such as fridges, dishwashers, washers, and dryers, as well as heating systems, to promote sustainability and minimize energy consumption.

    Fast and Secure Building

    A+ offers uninterrupted construction processes and security by providing a lifetime warranty on selected materials. Finally, we ensure adherence to all city building regulations and ordinances, help with financing options, and submit permit documentation.

    Frequently Asked Questions — FAQ

    What are the types of ADUs?

    The ADU types include detached ADUs, attached ADUs, garage conversions, basement ADUs, and others. Based on the place of manufacturing, we can also name prefab ADU units. Almost all of the construction processes for this ADU type take place at the factory, and the ADU building company transports it to the site ready-made, proceeding to installation.

    How do you do the foundation for an ADU?

    Although types of foundation may range from one project to another, the most common include slab-on-grade, crawl space, and full basement. Before choosing the right one, we estimate your property characteristics and unique conditions.

    Is an ADU worth the effort?

    Since ADU is smaller than a traditional house, it has a more affordable cost. Moreover, an ADU project may utilize your existing garage or other structure to transform it into a functional residential unit that can potentially bring you rental income. This allows you to offset the development price.

    Why do I need site analysis to complete the project successfully?

    Site analysis is one of the tools to confirm the feasibility of the project. A+ offers it for free, as without a proper site analysis, it’s possible to overlook essential aspects of the project. We estimate such factors as available space, utility connections, and potential obstacles.
