As one of Better Builders' trusted architectural partners, Longhouse Design Studio brings a deep understanding of the built environment, regularly collaborating on architectural projects that combine timeless design with modern functionality. In this post, Steven shares the top residential architecture and interior design trends shaping homes across Seattle and the greater Pacific Northwest in 2025.
With rising material costs, labor shortages, and sustainability top of mind, many homeowners are rethinking the construction process. Rather than searching for the rare vacant lot or tearing down and building from the ground up, they’re opting to remodel or repurpose existing structures, preserving foundations or structural bones to reduce environmental impact and construction emissions. This adaptive reuse approach often results in “transitional” homes that elegantly blend historical charm with contemporary interior palettes and smart home features.
In recent years, this approach has gained momentum throughout the Pacific Northwest as homeowners seek to stretch budgets, breathe new life into old buildings, minimize their carbon footprint, and avoid lengthy build times.
Seattle’s zoning changes are reshaping urban architecture by encouraging middle housing strategies like modular ADUs (Accessory Dwelling Units) and DADUs (Detached ADUs). These additions offer eco-friendly density without sacrificing livability. Whether used for rental income, a private guest space, or multigenerational living, these smart, flexible units are becoming a staple in neighborhoods like West Seattle, where space is at a premium.
Incorporating modular design and efficient floor planning, these secondary structures support a more resilient, community-oriented built environment.
Steven is seeing today’s homeowners design with the future in mind by incorporating features like ground-floor primary suites, accessible bathrooms, and adaptable layouts. Rather than cycling through new homes every few years, more people are investing in spaces that evolve to meet changing needs over time.
Designing for aging in place not only supports comfort and safety but also reduces the environmental impact of frequent moving and reconstruction.
Gone are the days of one-size-fits-all open floor plans. While open concepts remain popular, there is a growing demand for a more nuanced approach—spaces that feel intentionally designed for specific moods, activities, and moments. Homeowners now describe how they want their homes to feel—using words like cozy, energizing, calm, and creative—to guide the design process.
Rather than removing every interior wall, homeowners are embracing subtle spatial boundaries through layout, materiality, and even color to create distinct experiences in each area.
This emotional approach to floor planning makes the home feel more personal, more grounded, and ultimately more livable. It also allows for better acoustic control, improved energy efficiency, and spaces that support daily rhythms without feeling chaotic or undefined.
In short, it’s not just about how a home looks—it’s about how it feels to live in.
As daily life becomes more digitized and city life more crowded, people are craving homes that reconnect them to the natural world. Biophilic design—a rising trend in the architecture industry—goes beyond indoor-outdoor flow. It’s about creating an immersive connection to nature through natural elements like greenery, reclaimed wood, stone, and ceramics. In Seattle, where gray skies are common, maximizing natural light through large windows, skylights, and transom ventilation is especially impactful.
This nature-forward approach creates a home that nurtures mental well-being, enhances the user experience, and supports a healthier work-from-home balance, offering a calming reprieve from the fast-paced life just outside the front door.
Sustainability isn’t just a trend—it’s reshaping how homes are built. Homeowners are prioritizing eco-friendly materials and construction methods that lower a home’s environmental impact and operational costs. Popular sustainable choices include:
While some sustainable design elements may come with higher upfront costs, they often lead to energy savings and lower lifetime maintenance. In regions facing increasing climate risks, resilient materials like brick, concrete, and metal are becoming more common—especially in wildfire-prone areas.
Minimalism isn’t going away, but it is evolving. Once characterized by all-white walls, hard edges, and stark spaces, today’s minimalist homes are embracing warmth, texture, and personality. Steven describes this trend as “warm minimalism”—a design approach that retains the clean lines and uncluttered feel of minimalism, while incorporating texture, natural elements, and organic shapes. Think earthy palettes, soft lighting, and natural materials like wood, stone, and matte ceramics layered into thoughtful, livable interiors. Instead of feeling stark or sterile, these spaces feel lived-in, grounded, and inviting.
This trend also shows up in form: arched doorways, curved furniture, and softer silhouettes are replacing the sharp, boxy forms of the past. The result is a more organic, approachable take on modern home design that soothes and comforts with visual clarity and functionality.
Like many industries, AI is transforming the field of architectural design. While Steven doesn’t embrace AI for design decisions, he does leverage it to enhance communication and streamline early-stage design planning with his clients. AI-generated renderings enable clients to quickly visualize massing, height, and layout, transforming abstract floor plans into tangible visual concepts, often in real-time.
This early feedback loop enhances the construction process by reducing miscommunication, expediting decision-making, and improving the user experience. Instead of waiting weeks for costly final renderings, homeowners can explore real-time design options, experimenting with materials, shapes, and layouts.
While Steven still prioritizes human creativity over automation, these technological advancements are an undeniable asset to both the architect and the client. For busy homeowners, especially those balancing work and family life, this type of agile, visual collaboration keeps the project moving smoothly and efficiently from the outset.
Outdoor living isn’t new, but it’s being reimagined. In dense Seattle neighborhoods, small yards and patios are becoming multifunctional extensions of the home. Modular decks, screened-in porches, and rooftop gardens create spaces for cooking, entertaining, and relaxing, often enhanced with eco-friendly features like solar panels, fire pits, and outdoor heaters.
Vegetation and privacy structures allow these compact oases to feel secluded without compromising on the look or function. Whether it’s a morning coffee spot or an evening lounge zone, outdoor living spaces are now essential components of thoughtful architectural projects.
As this year progresses, it’s clear that the future of architecture in the Pacific Northwest is less about following fads and more about creating authentic, adaptable homes that support everyday life. Design trends are about creating spaces that support the way we want to live, through seasons, life stages, and everything in between.
At Better Builders, we’re proud to work with thoughtful partners like Longhouse Design Studio to bring these ideas to life. Whether you’re remodeling an older home or starting fresh with a new addition, these trends offer inspiration grounded in practicality and purpose.
