      300 sq. ft. ADU Floor Plans

      Backyard cottages differ in size and layout, catering to diverse homeowners needs. A 300 square feet ADU is a small accessory dwelling unit that may suit a young couple that just started out and need an affordable living space. Or, if you wish to accommodate your elderly parents in the comfort vicinity of your primary residence to reduce tedious visits between houses.

      In any case, the 300 square feet ADU project by A+ Construction & Remodeling offers an effective floor plan that utilizes the limited space in the most beneficial way.

      300 sq. ft. ADU betenfits

      Careful consideration is required to pick the right type and size of ADU for your property. For instance, some properties are narrow, cramped, or have other structures scattered around them, leaving little suitable place for construction. Otherwise, you may have enough space but not enough money to pay for a larger-scale project. Also, it makes sense to take into account privacy considerations: a detached ADU always has more privacy than an attached one.

      A 300 square feet studio ADU boasts the following perks:

      1. Efficient use of space;
      2. Easy access to all parts of the ADU house;
      3. Ability to accommodate enough functional furniture and appliances;
      4. Minimalistic design that allows you to keep your area decluttered;
      5. Budget-friendliness.

      Whether you decide to create a rental unit, a guest house, or a granny flat for your aging loved ones, we hope our studio ADU of 300 sq. ft. will serve as a useful input!

      300 sq. ft. Studio Unit Features

      Our 300 square feet model has an open floor plan. The benefits of open floor plans are an opportunity to maximize habitable rooms and create a comfortable living area by combining the sitting room, sleeping, and kitchen areas into one open space. It incorporates only essential furniture and storage solutions, facilitating easy walking throughout the space.

      300 square feet ADU is:

      • easy to clean and maintain;
      • gathers less clutter;
      • has many windows for natural light;
      • encourages you to spend more time outdoors.

      Cozy Spot for Relaxation

      A+ ADU model of 300 sq. ft. boasts a generous living area with a sofa and a small coffee table in front of the TV. The furniture-free center of the ADU allows for unobstructed movement and a feeling of spaciousness despite moderate general footage.

      Sufficient Lighting and Fair Colors

      White-painted walls and brown, beige, and gray accents create a minimalistic yet stylish and modern design complemented by contemporary decor. Good lighting adds a sense of flow between the distinct types of living spaces, creating a more cohesive and seamless ambiance.

      Dedicated Sleeping Area and Bathroom

      We placed the bedroom in the corner to maximize free zones and to provide some privacy to the ADU residents. The bed is spacious enough for two people, catering to both individuals and couples. Also, the bedroom area has convenient closets to store your belongings. The bathroom contains a full shower/tub, a sink, and a toilet, providing essential facilities for the inhabitants.

      Premium Features and Durability

      A+ uses quality materials in the interior and exterior finishes to withstand the test of time. Our surfaces resist water, mold, rot, and pests and are toxic-free. Also, the ADU boasts an array of amenities like all-electric appliances, a full-size washer and dryer, along with other high-quality fixtures. The functional wooden kitchen combines elegance with convenience of use, its premium material cabinets adding a touch of luxury to your property.

      All Appliances Included

      Our 300 square feet ADU features a laundry area, fridge with top freezer, dishwasher, and microwave in the kitchen, an effective heat pump, and insulation for energy efficiency.

      Frequently Asked Questions — FAQ

      Do ADU units have a mini-kitchenette or a full-fledged kitchen?

      All units are different, so it depends on your preferences, available space, and budget. The law does not regulate this matter, so if you decide to build an ADU with a full-sized kitchen or small kitchenette, a dining area, or a vast living room, you can do it, given you abide by laws and regulations. Otherwise, you won’t be able to obtain building permits.

      What are the different types of ADUs?

      There are ADUs that you construct from scratch and ADUs you convert from a basement, a garage, or other structures in your backyard. New-construction ADUs are attached and detached ADUs. The second type is conversions and internal ADUs. Typically, all of them have their own separate entrance.

      Can I choose custom built-in storage solutions, doors, curtains, or a deck for my ADU?

      Sure. If you have your own design and layout in mind or have some special consideration for your ADU style, we’ve got you covered! A+ is ready to create a unique work of art on your property, whether it is a pitched roof, glass door, or specific wall sconces.

      Does an ADU building process require landscaping?

      It depends on such factors as local regulations and specific property needs (for example, the need for site grading to build a solid foundation). Contact A+ Construction and Remodeling professionals to learn more about what the ADU building process is!
