Hottest Interior Design Trends This Summer for Your New Modular Home

Every season brings a fresh wave of interior design inspiration, such as the recent trend toward more neutral colors and a shift toward broader spaces shaped by comfort, homeowner individuality, and intentional living. However, the best trends this summer aren't really about copying a showroom or chasing a photo-perfect room. 

The most successful interiors are the ones that feel personal and that reflect how you actually live. This is why customizable modular homes are so popular. You can begin with a floor plan you love, then personalize the finishes, kitchen details, bath selections, storage, porches, and smart-home features around your lifestyle.

At Designer Homes of Pennsylvania, personalization is built into our home-building process, including a wide range of interior and exterior options. Looking for some design inspiration?

Warm, Livable Spaces Are Defining Summer Designs

Interior designs are moving away from cold, overly stark interiors and toward rooms that feel softer, warmer, and more welcoming, according to Better Homes & Gardens. Think creamy neutrals and palettes tied to comfort, intentional living, and natural materials. These design themes fit well with what many homeowners want: spaces that feel relaxed and inviting from day one, not trendy in a way that quickly feels dated.

These soft hues show up frequently in paint colors, cabinetry tones, flooring choices, and countertop selections in new modular homes. For example, see the 3D Tour of our Jade Tree model home, with soft whites, beiges, and wood tones with layered neutrals that make living areas feel timeless and fresh for summer.

Express Yourself in Your New Modular Home

Another major shift this year is toward interiors that feel more expressive and less cookie-cutter. Better Homes & Gardens has described 2026 as the “Year of Whimsy” and individuality in home design, with homeowners embracing charming details, softer curves, playful accents, and design choices that tell a story. And the American Society of Interior Designers recently released a trends outlook report indicating that homeowners are seeking spaces that support identity, wellness, and emotional comfort, rather than rigid, one-style-fits-all designs.

This doesn’t mean you have to go overboard when choosing design features for your new home. It’s more about choosing details that make the home feel like yours. Maybe it’s a kitchen island color that stands out a bit more or statement lighting. Perhaps it’s adding built-in storage that supports your daily routine or creating a mudroom, porch, or reading nook that reflects how your family actually uses the space. A customizable modular home lets you make these decisions early, rather than trying to retrofit personality into a finished home later.

Soft Purples Are Having a Moment

One way to add your own personal touch to your home is to add a splash of color to neutral palettes. Design experts report that lilac is making a splash as one of the more popular home accents, as homeowners look for ways to add hues that feel uplifting and keep a home from looking overly formal.

However, too much lavender can overwhelm the senses (literally and figuratively). Choose measured ways to add lavender or other splashes of color, such as a powder room vanity, accent pillows, decorative accessories, a painted ceiling, or a small feature wall. This approach works well in custom modular homes, where you can choose finish selections that are balanced and not overly trendy.

Add Layers for Comfort

While many design trends focus on color and playful details, comfort remains a major driver in residential design. Consider a relaxed, lived-in interior with layered textiles, comfortable nooks, and a more personal mix of old and new elements. Adding interior design layers can transform a new house into a real home that feels truly lived-in. Additionally, your style choices should support real life. This could mean adding more pantry storage, choosing durable yet attractive flooring, planning a family-friendly entry, selecting cabinetry to reduce clutter, or designing a primary bath that feels calm and functional. A beautiful house is important, but a home that works well day after day is even better. With modular construction, many of these choices can be built into the floor plan from the beginning.

Small Details Can Make a Big Impact

Not every homeowner wants a bold, dramatic interior, but many do want a few standout features that make the home memorable. Better Homes & Gardens design experts suggest adding graphic stripes to colorful accents to create playful visual moments without taking over an entire room. Even a small design choice can become a focal point when it is used intentionally.

For choosing your modular home features, consider a more eye-catching backsplash, upgraded cabinet hardware, a contrasting island, a distinctive front door color, a covered porch with extra design character, or a better lighting package in the kitchen or bath. These are just a few of the small details that elevate a home and make it feel custom, even when the overall palette stays classic.

Why Modular Homes Work So Well for Design-Minded Buyers

One of the biggest myths about modular homes is that they limit your design freedom. In reality, the opposite is often true when you work with a builder who prioritizes customization. At Designer Homes of Pennsylvania, we encourage buyers to explore a wide range of design options online and to visit our model homes for ideas and inspiration. There’s no substitute for seeing quality craftsmanship up close to visualize the home of your dreams.

With a modular home, you can start with a strong floor plan and then adapt the details to match your lifestyle, whether that means a more open kitchen, better storage, upgraded baths, a porch for entertaining, or a cleaner, more connected smart-home setup.

The hottest interior design trends this summer aren’t really about chasing a perfect room. They’re about creating spaces that feel warmer, more expressive, more comfortable, and better suited to everyday life.
