Accessory Dwelling Units (ADUs) are an excellent way to add extra living space, rental space, or a private guest suite to your property. However, with limited square footage, smart ADU design ideas are crucial to maximize functionality with complete comfort.
This blog explores space-saving ADU storage solutions, functional accessory dwelling unit design strategies, and ADU interior design for small spaces to help you create a stylish, efficient, and livable compact home.
10 Tips: ADU Design Ideas
1. Open Floor Plans: For Flexibility
An open-concept layout eliminates unnecessary walls, making a small ADU feel larger. Combine the living, dining, and kitchen areas into one cohesive space. Use furniture and rugs to define zones without closing off areas.
Pro Tip: A kitchen island with seating doubles as a dining table and prep space.
2. Multi-Functional Furniture
Invest in pieces that serve multiple purposes:
- Murphy beds – Conveniently fold into the wall, creating extra floor space when not in use.
- Sofa beds – Provide seating by day and a guest bed at night.
- Storage ottomans – Offer seating + hidden storage.
- Fold-down desks – Create a workspace that disappears when not in use.
3. Vertical Storage Solutions
When floor space is limited, think upward:
- Floor-to-ceiling shelving – Maximizes wall space for books, decor, and essentials.
- Floating shelves – Keep surfaces clutter-free.
- Over-the-door organizers – Perfect for shoes, pantry items, or cleaning supplies.
- Lofted beds – Free up space underneath for a desk, couch, or storage.
4. Built-Ins: Space-saving ADU Storage
Custom-built-ins make storage blend into the design:
- Under-stair drawers – Utilize every inch of an ADU with stairs.
- Window seat storage – Adds seating + hidden compartments.
- Kitchen toe-kick drawers – Extra space for rarely used items.
5. Appliances: Compact & Space-Saving
Standard-sized appliances can overwhelm a small ADU. Opt for:
- 24-inch dishwashers
- Apartment-sized refrigerators
- Combination washer-dryer units
- Induction cooktops (sleeker than bulky stoves)
6. Doors: Sliding & Pocket
Traditional swinging doors take up valuable space. Instead, use:
- Sliding barn doors – Stylish and space-efficient.
- Pocket doors – Tuck neatly into the wall when open.
- Room dividers – Offer flexibility in open layouts.
7. Mirrors: Light Colors & Strategic
Make a small ADU feel airy and bright:
- Light paint colors (whites, soft grays, pastels) reflect light.
- Large mirrors make rooms feel more open.
- Glass partitions maintain an open feel while dividing rooms.
8. Outdoor Living Extensions
Expand usable space by incorporating:
- A small deck or patio – Adds square footage for relaxing or dining.
- Foldable glass door – Blurs the line between indoor and outdoor living.
9. Staircase Storage Solutions
If your ADU has a loft or second level, transform the staircase into functional storage:
- Pull-out drawers built into each step for shoes, linens, or pantry items.
- Open shelving underneath for books, decor, or baskets.
- Hidden cabinets along the side for bulky items like luggage or seasonal decor.
This clever use of often-wasted space keeps your ADU clutter-free without sacrificing style.
10. Foldable & Expandable Features
Incorporate elements that adapt to your needs:
- Foldable dining tables – Mount on the wall and expand only when needed.
- Retractable clotheslines – Hidden in cabinets for laundry days.
- Expandable kitchen counters – Pull-out surfaces for extra prep space.
- Nesting furniture – Stackable chairs/tables that tuck away neatly.
These flexible features ensure every inch of your ADU works harder for you.
