When Your Home Needs to Grow With You
Life has a way of changing faster than we expect. The spare room that once housed occasional guests now needs to be a permanent bedroom for a growing teenager. Your home office, carved out of a corner of the living room, desperately needs dedicated space where you can close the door and focus. Perhaps aging parents need a comfortable suite where they can maintain independence while staying close to family.
Home additions in the Pacific Northwest offer the perfect solution for families who love their location but need more space. At Zee Design & Build, we've spent over a decade helping families throughout King, Snohomish, Skagit, and Island Counties expand their homes seamlessly. From cozy bedroom additions in Seattle's established neighborhoods to sun-drenched family rooms in Bothell's tree-lined streets, each addition we create feels like it was always part of your home's original design.
Ready to explore how we can expand your space? Let's discuss the possibilities for your home.
The Art of Seamless Home Expansion Through Home Additions
Creating a home addition that feels genuinely integrated requires more than just building new walls—it demands an understanding of architecture, structural engineering, and the subtle details that make a house feel cohesive. When done correctly, guests should never be able to tell where your original home ends and the addition begins.
Our process starts with understanding not just what you need, but how you live. Do you need a quiet retreat where teenagers can have independence, or an open family space where everyone naturally gathers? Are you looking to add value for a future sale, or creating your forever home where grandchildren will play? These conversations shape every decision we make.
Site assessment reveals the hidden opportunities within your property. Our Kirkland-based design & build team of general contractors, home remodelers and structural engineers evaluate your home's existing structure, examining load-bearing walls, foundation systems, and utility locations. We consider lot lines, setback requirements, and neighborhood covenants to ensure your addition not only meets building codes but respects your community's character.
The foundation work for Pacific Northwest additions requires special attention to our region's unique challenges. Excavation and concrete work must account for our moisture-rich soil conditions, while waterproofing systems protect your investment from the elements. When we tie new framing into your existing structure, every connection is engineered to handle both seismic activity and the seasonal expansion and contraction that comes with our climate.
Perhaps most critically, we ensure your addition's exterior seamlessly matches your home's existing architecture. Rooflines flow naturally from old to new, siding materials and colors create visual continuity, and window placement maintains your home's balanced proportions. Inside, flooring transitions smoothly, ceiling heights align perfectly, and even details like trim and hardware maintain consistency throughout your expanded home.
Comprehensive Home Addition Types for Every Need
Master Suite Additions: Luxury Bedroom Retreats
Master suite additions create private sanctuaries that transform your daily living experience. These expansions typically include spacious bedrooms with walk-in closets, spa-like master bathrooms with soaking tubs and separate showers, and often private decks or patios. Many homeowners also incorporate sitting areas, home offices, or exercise spaces within their master suite additions.
Modern master suite additions emphasize natural light through strategically placed windows and skylights, while maintaining privacy through thoughtful positioning on your property.
Sound insulation ensures these retreats remain peaceful havens, separate from household activity.

Family Room & Great Room Additions: Heart of the Home
Family room additions create the gathering spaces that modern homes often lack. These open, welcoming areas become natural focal points where families spend quality time together. Great room additions take this concept further, combining family room, dining, and kitchen areas into expansive, flowing spaces perfect for entertaining and daily family life.
We design these additions with cathedral ceilings, exposed beams, and large windows that create bright, airy atmospheres. Built-in entertainment centers, cozy fireplaces, and seamless outdoor access through sliding glass doors make these spaces both functional and inviting.

Kitchen Additions & Expansions: Culinary Command Centers
Nothing says "home" quite like the warmth of exposed timber beams and the crackle of a stone fireplace. Rustic custom homes celebrate the raw beauty of the Pacific Northwest, using materials that honor our region's logging and craftsmanship traditions.
These homes feel like they've grown from the landscape itself. Massive timber frames create cathedral ceilings that inspire awe, while cozy reading nooks tucked under staircases invite quiet contemplation. Stone hearths become gathering places for families, and covered porches extend living spaces into the forest beyond.
Does a rustic custom home sound right for you?

Bedroom Additions: Growing Family Solutions
Individual bedroom additions provide essential space for growing families. Whether creating children's bedrooms with built-in storage and study areas, or guest bedrooms with private bathrooms, these additions offer flexibility and privacy that transforms family dynamics.
Teen bedroom additions often include separate entrances, study alcoves, and private bathroom access. Guest bedroom additions can include sitting areas and workspace functionality, making them dual-purpose rooms that serve your family's changing needs.

Sunroom & Three-Season Room Additions: Indoor-Outdoor Living
Sunroom additions capture the Pacific Northwest's natural beauty while providing comfortable indoor spaces year-round. Floor-to-ceiling windows and glass doors create bright, airy rooms that serve as breakfast areas, reading nooks, and peaceful retreats.
Three-season rooms offer similar benefits with the flexibility of opening to outdoor spaces during pleasant weather. These additions often feature cathedral ceilings, tile or hardwood flooring, and ceiling fans for optimal comfort during warmer months.

Second-Story Additions: Vertical Expansion Solutions
Second-story additions maximize living space on smaller lots throughout Seattle and surrounding communities. These vertical expansions can double your home's square footage while maintaining yard space and neighborhood character.
Upper-level additions work particularly well for master suites, teen retreats, or home office spaces that benefit from elevated views and enhanced privacy. The structural engineering required for second-story additions demands specialized expertise to ensure proper support and integration with existing foundations.

Let’s start the conversation about what that could look like.
In-Law Suite & ADU Additions: Multigenerational Living
Accessory dwelling unit (ADU) additions and in-law suite expansions address the growing need for flexible multigenerational housing. These self-contained living spaces include private bathrooms, kitchenettes, and separate entrances while maintaining connection to the main home.
In-law suites offer aging parents independence with nearby family support, while ADU additions can provide rental income opportunities or private spaces for adult children. We navigate local zoning requirements and building codes to ensure these additions meet all regulatory requirements.
Are you looking a new ADU? Let’s start the conversation about what that could look like.
Home Office & Study Additions: Dedicated Work Spaces
Home office additions create productive work environments separate from household distractions. These dedicated spaces often include built-in desks, extensive storage, and enhanced lighting designed for productivity and video conferencing.
Study additions serve growing families by providing quiet spaces for homework, reading, and academic pursuits. We design these rooms with ample natural light, comfortable seating areas, and organizational systems that support learning and concentration.

Dining Room Additions: Formal Entertaining Spaces
Formal dining room additions create elegant spaces for holiday gatherings and special occasions. These rooms often feature architectural details like coffered ceilings, wainscoting, and built-in china storage that reflect your home's overall style.
We position dining room additions to flow naturally from kitchen and living areas while maintaining the formal atmosphere that makes special meals memorable. Large windows and French doors often connect these spaces to outdoor patios for extended entertaining possibilities.

Mudroom & Utility Additions: Organized Living Solutions
Mudroom additions provide essential organization and storage that keeps homes tidy and functional. These practical spaces include built-in storage for coats, shoes, and sports equipment, along with utility sinks and folding areas for household tasks.
Utility room additions house laundry equipment, water heaters, and household storage while keeping these functional necessities separate from living spaces. We design these areas for maximum efficiency and easy maintenance.

Garage Additions & Conversions: Multi-Purpose Flexibility
Garage additions provide protected parking while often including workshop areas, storage lofts, and utility spaces. Detached garage additions can include upper-level spaces for home gyms, studios, or additional storage.
Garage conversions transform existing spaces into living areas, home offices, or recreation rooms. These projects require careful attention to foundation, insulation, and electrical systems to create comfortable interior environments.

What Drives Everything We Do at Zee Design & Build
Behind every home addition we build are the principles that have guided Zee Design & Build since our founding. These aren't just words on our website—they're the foundation of how we approach every project, every decision, and every relationship with our clients.
Efficiency in Every Detail: Home additions are complex projects that require careful coordination of multiple trades and systems. We've refined our process for over a decade to maximize every resource, every hour, and every decision. This efficiency doesn't mean rushing—it means working smarter so your family can enjoy your expanded space sooner.
Precision That Matters: In addition construction, structural integration is critical for both safety and aesthetics. Our commitment to accuracy means ensuring every connection between old and new construction is engineered correctly, every measurement aligns perfectly, and every finish detail maintains consistency throughout your home.
Excellence Without Compromise: We hold ourselves to the highest standards because your home deserves nothing less. When challenges arise during construction (and they often do with additions), we take immediate ownership and develop solutions that often make the final result even better than originally planned.
Innovation Through Listening: The most successful additions come from truly understanding your family's unique needs and lifestyle patterns. We don't believe in generic room additions. Instead, we listen carefully to how you live and use innovative design solutions to create spaces that serve your family perfectly.
Why Families Choose Zee Design & Build
When you're investing in a home addition—often a significant portion of your home's value—the contractor you choose makes all the difference. While other builders in the Seattle area may promise similar results, our approach sets us apart in meaningful ways.
Many contractors treat additions as separate projects, but we believe seamless integration requires understanding your entire home's character and systems. We source premium, eco-friendly materials that not only match your existing home but often improve upon it. Our partnerships with local organizations like 911 Glass Rescue and the Rotary Club reflect our deep commitment to both environmental responsibility and community involvement.
Perhaps most importantly, we use advanced 3D design technology that lets you visualize your addition before construction begins. This isn't just convenient—it's transformative. You can see how your new spaces will flow with existing rooms, understand how natural light will change throughout the day, and make adjustments while changes are still simple and cost-effective.
While some contractors leave you wondering about progress and timelines, we provide clear communication and efficient processes that minimize disruption to your daily life. Home addition construction means living in a construction zone, but our organized approach and respectful work practices make the experience as smooth as possible.
Why Professional Addition Construction Matters for Home Additions
Home addition projects involve complex structural engineering, code compliance, and system integration that goes far beyond typical home improvement projects. What might look straightforward often involves relocating utilities, reinforcing existing structures, and coordinating multiple building systems in ways that require professional expertise and specialized tools.
Our specialists bring decades of combined experience with Pacific Northwest construction challenges, from foundation waterproofing to seismic engineering. More importantly, we understand how additions affect your home's overall systems—how new electrical loads impact existing panels, how HVAC systems need modification to serve expanded spaces, and how plumbing integration requires careful planning to maintain consistent water pressure throughout your home.
When you build with Zee Design & Build, you're not just getting construction expertise—you're investing in craftsmanship that will serve your family for decades. Our additions are engineered to withstand everything the Pacific Northwest can deliver, from winter storms to seismic activity, while maintaining their beauty and functionality as integral parts of your home.

What Our Clients Say
"After moving from California, my husband and I bought a 1964 rambler. it looked like it hadn't seen any love or attention since the day it was built! Erik and his crew gutted the entire house and, from start to finish, ALL was done in around 4 months. We are thrilled with the outcome!"
- - - -
My daughter recommended Erik to my husband and i, and he did a full kitchen remodel for us. Our house was built in 1999, and we were looking to do new cabinets. We met with Erik and were so impressed by his visions and experience that we decided to instead do a full kitchen remodel. Erik and his team did new cabinets, appliances, countertops, trim...AND an island with cooktop and seating. Erik was extremely friendly, communicative and organized. We definitely plan on working with him again for future projects!"
- - - -
"I used Erik's company to finish renovations on our property of 380 apartments. Not only was he very professional, but the speed and quality and scheduling of each unit was done with precision and created great results. I would without hesitation use Erik's company again."
