How the Right ADU Design Ideas Can Increase the Value of the Space?

Would you believe it if I told you bright, organized, and functional spaces feel more valuable?

While no research studies (that I could find) support the statement, you will be a believer once you experience the concept. 

I have personally seen this phenomenon with my own eyes time and time again.

It is not about the actual value but perceived value. The perceived value could support a higher monthly rent if your ADU is a rental. Who couldn’t use a little additional income? 

“Clutter can actually take off 5 to 15 percent of a home’s value”, says Sissy Lappin, a top real estate agent. 

Ideas for Maximizing Space and Functionality in an ADU

1. Fold-Down Tables & Beds Are Your Friend

Maximize your small ADU’s limited square footage with fold-down tables and Murphy beds.

This design contempt offers a versatile dining or work area that tucks away when unused or a bedroom that becomes an open area during the day. 

You can free up floor space, keeping it open and adaptable.

2. Use Multi-purpose Furniture

It is not secret an ADU may have limited square footage. Invest in multipurpose furniture pieces like sofa beds or ottomans with storage. 

These smart solutions serve dual purposes, enhancing functionality without sacrificing style. Bookshelves that serve as room dividers and storage are a nice addition because of the height they offer to separate the space. 

In the prefab Boxabl, the living room is separated by the sleeping space with a piece of furniture that holds the TV, which is on a lazy Susan.

3. Pocket Doors Are Life Savers in Small Areas

Pocket doors slide into the wall, a perfect example of a space-saving alternative to traditional swinging doors, making them ideal for compact areas where every inch counts. 

Often, there is not enough space for a door to open and close fully. Pocket doors to the rescue! If you are building an ADU from scratch, see where you could add pocket doors to your plan to take advantage of the space-saving they offer.

4. Futons or Daybeds Serve Two Purposes

Futons and daybeds offer comfortable seating by day and transform into cozy beds at night, ideal for guests or as a primary sleeping area.

These are perfect if your space is a second dwelling serving a dual purpose, like office and guest spaces. 

5. Consider Slim Designs

Choose furniture with slim designs to maintain a sense of openness. Narrow shelves, sleek chairs, and slender tables maintain functionality without overcrowding.

6. Scale to Your Advantage

Select furniture and decor that are scaled appropriately for your accessory dwelling unit. Smaller, proportionate pieces prevent the space from feeling cramped, maintaining a balanced aesthetic. 

Small furniture can give you more floor space, creating a cozy space.  

7. Use Floating or Ceiling mounted Shelves

Floating and ceiling-mounted shelves provide storage and display spots without the bulkiness of cabinets or bookcases, keeping your floors clear and making the room appear larger. 

Using a chunky shelf can create that modern farmhouse feel. Floating shelves in a bathroom are a great addition because different-sized nooks always scream for something to be added. 

8. Hang Your Dishes

Hanging your dishes, pots, and pans frees up valuable cabinet space and adds a unique, functional element to your kitchen.

Consider it art!

9. Bookshelves for Everything

Bookshelves aren’t just for books; they’re versatile storage solutions for various items, from kitchenware to decorative objects, helping to organize and declutter.

Add inexpensive matching baskets to the shelf to create a catchall for small items. From a distance, the collection of baskets creates simple lines. 

10. Try Built-in Storage

Built-in storage solutions, such as recessed shelving or under-bed drawers, are perfect for ADUs, providing essential storage without encroaching on the living area.

Ideas for Enhancing Natural Light and Openness in Small Spaces

11. Skylights to Bring in More Natural Light

Skylights are show-stoppers in ADUs, inviting ample daylight from above and making a small space feel larger and more welcoming. Having enough light in certain parts of the room can be solved with skylights.

12. Increase Natural Light

Boost the brightness and sense of space by strategically placing windows to enhance the flow of natural light throughout the day. Most tiny house adopters crave light in their tiny space.

13. Use Light-Colored Furniture and Walls

Embrace light hues for walls and furniture to reflect sunlight and amplify the sense of openness, making the ADU feel airy and more spacious.

14. Keep Windows Clear of Obstructions

Optimize light entry by unblocking window areas, ensuring natural light can freely illuminate your room, enhancing aesthetics and energy efficiency.

15. Install a Sliding Glass Door

A sliding glass door saves valuable space, integrates more natural light, and offers a seamless transition to outdoor areas.

Ideas for Optimizing Indoor/Outdoor Flow in Your Space

16. Prioritize Indoor/Outdoor Flow

Design your space with elements like large sliding doors or continuous flooring to create a seamless transition between indoor and outdoor living areas. You can get the feeling of more space by just tricking the eye. 

The design below perfectly illustrates how indoors and outdoors are connected. The open space between the living structure and the flex room is utilized for dining, living, and relaxing.

19. Include a Solar Light Path to Your ADU

Illuminate the path to your detached ADU with solar lights, adding a charming and practical touch that enhances safety and accessibility.

20. Select the Best Landscaping Options

Choose landscaping that complements the size and style of your structure, such as low-maintenance plants or small trees, to design an inviting outdoor environment.

21. Bifold Doors for Seamless Indoor-Outdoor Transition

Bifold doors can dramatically open up the space, blending the indoors with the outdoors and offering flexibility in your living area.

Ideas on Decor and Aesthetics

22. Add an Accent Wall

An accent wall, painted boldly or adorned with wallpaper, can add depth and character to a room, making a stylish statement.

If you aren’t brave enough to paint an entire wall, consider painting a large canvas instead.

23. Choose Textured Decor

Incorporating textures through fabrics, wall hangings, or area rugs adds a layer of warmth and sophistication to your ADU’s interior design. 

Don’t be afraid to decorate your adu space to create visual interest. Here are a few options to add texture:

  • Wall art
  • Vases
  • Storage Containers
  • Accent pillows
  • Bookends
  • Lamps
  • KnickKnacks

24. Add Window Decorations

Dress up your windows with tasteful curtains or blinds that complement the overall design theme, offering style and functionality.

25. Use the Right Rug

A well-chosen rug can anchor the room, define the space, and add a cozy, inviting feel to your room, enhancing comfort and aesthetics. 

If your bedroom and living space are not divided by a wall, a rug can help anchor the room. 

26. Personalize the Space

Infuse the space with personality by incorporating personal items, artwork, or unique decor pieces that reflect your style and make the space feel like home. 

Adding items of high value is not suggested if the space will be a rental. 

27. Choose Bold Designs

Don’t avoid bold design concepts and elements, like striking art pieces or unique furniture, to create a focal point and add visual interest. 

While you won’t want to use a bold interior design on all four walls, choose a single wall to accent your small adu interior.

28. Go Luxe When in Doubt

Follow the lead of popular interior designers and sprinkle in a touch of luxury with high-quality materials or elegant fixtures in your backyard cottage. 

You can elevate your room’s look and feel, making it more upscale. One or two will do. 

29. Minimalist Decor for a Clutter-Free Look

Embrace a minimalist approach in decor to keep the space uncluttered and open, emphasizing functionality and clean lines for a modern look.

Ideas for Reflective and Transparent Elements for your ADU

30. Mirrors Are Your Friends

Strategically placed mirrors can visually expand your tiny house, reflecting light and views to create a sense of depth and openness. 

When you reflect light in a smaller space, the room opens up.  

31. Opt for Reflective Materials

Utilize reflective materials in fixtures, hardware, or decor to enhance light distribution and add a subtle, sophisticated sparkle to your interior design.

Ideas for Functional Additions and Utilities

32. Check Out Tankless Water Heaters & Solar Panels

Consider installing a tankless water heater offering energy efficiency and space-saving benefits, ensuring you never run out of hot water. Solar Panels can help save on utility bills.

33. Use a Corner Couch

A corner couch can maximize seating in a compact space, providing comfort without overcrowding the living area.

34. Ottomans are Practical and Add Valuable Storage

Ottomans with built-in storage are perfect for small rooms, offering a versatile solution for seating, storage, and even a makeshift coffee table. 

You can hide things like extra linens if your ADU will be used to hold family members or other guests. 

35. Hooked on Hooks

Install hooks on walls or behind doors for an easy, space-efficient way to hang coats, bags, or towels, keeping your tiny home organized and clutter-free.

36. Smart Home Technology for Efficiency and Convenience

A vertical garden is a perfect solution for small outdoor spaces, allowing you to grow plants and herbs upwards, adding greenery without using much ground space.

38. Add Some Plants

Potted plants or small flower beds can bring life and color to your ADU’s outdoor area, creating a more inviting and relaxing atmosphere.

Many plants grow from a cutting, so you can invest in a few plants and multiply them through cuttings. It is a budget-friendly way to add nature to the space.

39. Drought-Tolerant Landscaping for Sustainability

Opt for drought-tolerant landscaping to minimize water usage while maintaining an attractive outdoor space, ideal for eco-friendly, low-maintenance living.
