Top Interior Design Trends for Boston ADUs

Accessory Dwelling Units, or ADUs, are starting to appear more often throughout Boston neighborhoods. Whether built above garages, tucked into basements, or placed in backyards, these smaller living spaces give homeowners a smart way to expand without the cost or commitment of a full-size home. With housing costs on the rise and more people needing flexible living arrangements, ADUs offer a solution that’s both practical and personal.

As the demand for ADUs grows in Boston, so does the attention to design. These spaces are much smaller than traditional homes, which means thinking creatively is a must. Interior design plays a big role in making ADUs not only look good but function well. From furniture choices to lighting and layout, every detail makes a difference—and staying current with trends can help you get the most out of your ADU investment.

Embracing Multi-Functional Spaces

One of the biggest challenges of ADU living is space. With limited square footage, finding ways to make each room serve more than one purpose is key. Multi-functional design is not just helpful—it’s necessary to make compact spaces feel comfortable and usable.

Here are some smart ideas that suit Boston homes:

- Fold-out furniture like Murphy beds that tuck away during the day

- Collapsible dining tables or wall-mounted desks

- Sofas or benches with built-in storage compartments

- Sliding partitions to transform open areas into private nooks

- Furniture on wheels that can be reconfigured as needed

One feature that works especially well in city living is the Murphy bed setup with surrounding cabinets. When not in use, it looks like a bookshelf or closet. When it's time for guests, it unfolds into a cozy bed with side storage ready to go.

Built-in storage is another go-to feature. Think of benches that double as chests or shelving built into narrow corners. Using vertical space helps minimize clutter without sacrificing personal touches. The more functional each inch becomes, the more comfortable and calm the living space will feel.

Sustainable And Eco-Friendly Designs

Sustainability is showing up in more interior design plans today, especially within ADUs. These compact homes give Boston homeowners a great chance to try out eco-smart materials and systems on a smaller scale.

Here are a few ideas gaining traction:

- Flooring made of bamboo or cork that’s durable and renewable

- Reclaimed wood for beams or countertops that adds character

- Recycled glass surfaces that bring style with less waste

- Low-flow toilets and shower heads that reduce water use

- Energy Star appliances to lower electric bills year-round

Having a well-insulated space is one of the most practical changes you can make. When walls and doors are sealed properly, your heating and cooling systems don’t have to work as hard. This matters in Boston where winters can be long and summers warm.

On top of that, choosing fabrics and finishes that naturally last longer can help future-proof the space. Go with neutrals, clean lines, and natural textures that age well. A design that feels calm and inviting today should still look fresh years down the road. It’s not just better for the planet—it’s easier on your wallet too.

Maximizing Natural Light

Natural light is one of the most effective ways to open up a small room. Even if your ADU has limited windows, the right design choices can help you brighten and visually expand the space.

Try starting with layout. Put core living areas—like the kitchen, living room, or desk area—around your largest windows. And if you're planning from the ground up, think about adding skylights or clerestory windows. These bring in natural light while still keeping privacy intact.

Your color scheme also plays a big role. Walls painted in light, airy tones reflect sunlight and make a room feel bigger. White, cream, or pale gray are all good choices. Use mirrors or glass surfaces to help reflect light around the space. And when it comes to window treatments, the lighter and simpler the better. Think sheer curtains or shades that let light in while still keeping a cozy feel.

Tech lighting has a place too. LED ceiling fixtures and smart bulbs can add light where the sun can’t reach. Under-cabinet lighting is great for kitchens and bathrooms, and dimmers let you create the right mood for any time of day or type of activity.

Smart Home Features That Make A Big Difference

A good ADU isn’t just about how it looks—it should work for you too. Smart home features can go a long way in making daily life smoother and more secure, especially in tight spaces where convenience matters.

Here are a few upgrades that Boston homeowners are adding:

1. Smart thermostats that learn your habits and adjust automatically

2. Lights on sensors or timers for energy savings and easy control

3. Compact laundry units that can be scheduled from your phone

4. Doorbell cameras and security alerts for added safety

5. Smart plugs that cut power to unused electronics

One useful setup for colder months in Massachusetts is tying your smart thermostat to an underfloor heating system. Instead of heating the whole unit, your flooring just gets warm enough to take the chill off. It feels high-end without driving up your energy costs.

The trick to smart design is knowing what to include. You don’t need every device available, just the ones that truly make the space easier to manage. Think voice control for lights, automatic blinds for comfort, or smart locks for keyless entry. Each one removes small daily stress points, which really adds up in a smaller home.
