Designing Small ADUs: Space-Saving Tips for Efficient Living

In a compact ADU, every square foot matters. Start by zoning your space—separate areas for cooking, sleeping and relaxing—and consider an open-concept plan that lets rooms flow together. L-shaped kitchens tucked into corners free up floor space, and lofted sleeping areas can turn a one-story footprint into a cozy two-level home.

Built-in storage reduces clutter and makes small homes feel bigger. Consider benches with hidden compartments, wall-mounted shelves that run to the ceiling and drawers under stairs or raised platforms. Murphy beds with integrated shelving allow a bedroom to double as a living room or office. Fold-down desks and vanities disappear when not in use.

Select furniture that serves more than one purpose. Sofas that convert into beds, coffee tables with storage and dining tables that fold against a wall are essential in tiny homes. When every item earns its place, the space feels uncluttered and purposeful.

Large windows and glass doors make a small interior feel spacious. Incorporate a private deck, rooftop garden or patio so occupants can enjoy outdoor living and entertain guests. Seamless indoor-outdoor flow expands the perceived footprint and makes the ADU feel like an extension of the main home.

Eco-friendly materials—recycled wood, green roofs, high-efficiency insulation—reduce environmental impact and improve comfort. Smart thermostats, lighting and security systems allow residents to manage the home efficiently and appeal to renters.

With thoughtful design, even a 400- or 600-square-foot ADU can offer all the comforts of a larger home. By combining clever layout planning, built-in storage, multifunctional furniture and abundant light, homeowners can create a stylish, efficient secondary dwelling that feels anything but cramped.
