How to Make a Small ADU Look Spacious with Smart Interior Design

Accessory Dwelling Units (ADUs) are one of the smartest ways to add living space to your property, whether for family, guests, or rental income. At Gather ADU, we specialize in designing and building ADUs that feel modern, functional, and comfortable, no matter the square footage. 

Because most ADUs are compact in size, maximizing space through thoughtful interior design is essential. With our expertise, the right design choices can transform a small ADU into a stylish, highly efficient, and spacious-feeling home.

‍Why Interior Design Matters for Small ADUs.

Interior design directly affects how a space feels and functions. In a small ADU, poor design choices can make the space feel cramped and dark. On the other hand, smart design strategies like using light colours, multifunctional furniture, and clever layouts create the illusion of more square footage and improve comfort. For homeowners working with Gather ADU, our design team focuses on maximizing every square inch so your ADU feels open, modern, and livable.

Smart Interior Design Tips to Make a Small ADU Look Spacious

In this guide, we’ll explore proven interior design strategies to make a small ADU look bigger, brighter, and more inviting. From choosing the right colours and layouts to incorporating multifunctional furniture and natural light, these tips will help you maximize every square foot of your ADU.

Use Light Colours to Open Up Your ADU

Light colours are one of the easiest design tricks to make a small ADU look spacious. By reflecting natural light, soft shades like white, beige, and pastels create brighter interiors that feel larger, open, and welcoming for residents or guests.

1. Walls: Stick to whites, soft grays, beige, or pastel tones.
2. Ceilings: Keep them light-colored to add height.
3. Accents: Add pops of colour with artwork, rugs, or cushions without overwhelming the space.

Light, neutral tones also create a timeless look, which is especially appealing if your ADU is used as a rental.

Maximize Natural Light in Your ADU

Lighting is essential in small ADU interior design because it shapes how spacious a room feels. Natural light especially helps expand visual boundaries, making compact living areas look brighter, open, and more comfortable while enhancing the overall design flow.

1. Install large windows or sliding glass doors.
2. Use sheer curtains instead of heavy drapes.
3. Incorporate skylights where possible.

At Gather ADU, we often recommend open floor plans with large windows to bring in as much natural light as possible. If natural light is limited, add layered artificial lighting with recessed ceiling lights, wall sconces, and under-cabinet lighting.

Choose Multifunctional Furniture

Choosing the right furniture is crucial in a small ADU interior design plan. Oversized pieces quickly overwhelm limited square footage, while multifunctional furniture like sofa beds, foldable tables, and storage ottomans maximizes usability, keeps the layout flexible, and prevents visual clutter. Smart furniture ideas for ADUs include:

1. Sofa beds or Murphy beds for flexible sleeping arrangements.
2. Foldable or extendable dining tables that save space when not in use.
3. Ottomans with storage that double as seating.
4. Wall-mounted desks to create a home office corner.

With the right multifunctional furniture, your small ADU stays uncluttered and efficient. Smart pieces provide storage, seating, and flexibility, ensuring every inch serves multiple purposes without compromising comfort or style.

Optimize Vertical Space with Smart Storage

Storage in a compact ADU must be planned strategically to avoid clutter. Instead of using only floor space, smart vertical solutions like tall cabinets, floating shelves, and built-ins maximize functionality while keeping the interior open and spacious.

1. Install floating shelves for books, plants, and décor.
2. Use tall cabinets in the kitchen and bathroom.
3. Add built-in storage under stairs or benches.
4. Consider lofted sleeping areas with storage below.

These smart storage solutions keep belongings neatly organized without overwhelming limited space, allowing your small ADU to feel open, tidy, and functional while maximizing comfort and modern interior design appeal.

Keep an Open Floor Plan

Walls and partitions often make a small ADU feel closed off and restrictive. An open floor plan connects the kitchen, dining, and living spaces seamlessly, enhancing natural light flow and creating a spacious, modern living environment. For privacy without walls, try:

1. Sliding barn doors.
2. Glass partitions.
3. Bookshelves as subtle dividers.

An open-concept ADU layout improves natural light flow throughout the home, making compact interiors feel brighter, larger, and more welcoming while maximizing both functionality and modern interior design appeal.
