You’ll receive complete architectural drawings, engineering specifications, and 3D renderings that show exactly what your finished DADU will look like.

Tired of navigating complex permitting alone? Let our experts handle it—call (425) 451-0174 to get started today.
Site Preparation & Utility Connections
Our construction team manages all site work required for your DADU project. We coordinate excavation and grading, establish proper drainage, connect to existing utilities or install new service lines, and prepare building foundations. Site preparation also includes protecting existing landscaping, managing construction access, and ensuring minimal disruption to your daily life.
Expert Construction Management
Experienced project managers oversee every phase of construction, coordinating skilled tradespeople, maintaining quality standards, and keeping your project on schedule. We manage all aspects of construction—from foundation and framing through mechanical systems, exterior finishes, and interior completions. Regular communication keeps you informed of progress while our expertise handles the countless details that ensure successful project completion.
Quality Construction & Craftsmanship
Your DADU is built by skilled craftspeople who take pride in their work. Unlike prefab units constructed in distant factories, your DADU is site-built specifically for your property. This approach allows for customization during construction, ensures proper integration with your existing property conditions, and provides quality craftsmanship that prefab alternatives cannot match.
Interior Finish Installation
All interior finishes are professionally installed by experienced craftspeople. We handle cabinet installation, countertop fabrication and installation, flooring installation throughout, fixture mounting and connection, appliance installation and testing, and all trim carpentry and finish details. Every element is installed to exacting standards that ensure both immediate beauty and long-term durability.
Final Inspections & Move-In Preparation
Before we hand over the keys, your DADU undergoes thorough quality inspections, final building department approvals, comprehensive cleaning, and system testing to ensure everything functions perfectly. We provide you with operating manuals, maintenance guidance for all components of your new DADU, and ongoing support to answer any questions.
Want a truly turnkey DADU experience? Call (425) 451-0174 to learn how we handle every detail from design to move-in.
Site-Built Quality vs. Prefab Limitations
Zee Design & Build specializes in site-built DADUs throughout Bellevue, Seattle, Kirkland, Renton, Bothell, Lynnwood and Edmonds—and there are important reasons why we’ve chosen this approach over prefab alternatives.
True Customization for Your Property
Site-built construction allows us to adapt designs to your specific lot conditions. We can adjust dimensions to maximize buildable space within setback requirements, position windows strategically for optimal natural light and privacy, relocate doors to improve traffic flow and outdoor access, modify layouts to accommodate existing utilities or landscape features, and adjust ceiling heights and roof pitches to comply with local restrictions while maximizing interior volume.
Prefab units, by contrast, come in fixed sizes and configurations that may not optimize your specific property’s potential.
Seamless Architectural Integration
When built on-site, your DADU can be designed to complement your existing home’s architectural style. Matching exterior materials, rooflines, window styles, trim details, and color schemes create cohesive property aesthetics that enhance overall curb appeal and property value. The result looks intentional and permanent—like a natural extension of your property rather than a dropped-in structure.
Superior Construction Quality
Site-built construction provides several quality advantages. Foundations are engineered specifically for your soil conditions and local requirements. Framing is constructed to meet or exceed code requirements without the compromises sometimes necessary in transportable structures. Material selections aren’t limited by transportation constraints—we can use the best materials for each application rather than the lightest options. Quality control happens throughout construction with regular inspections rather than relying on factory certifications.
No Transportation Limitations
Site-built DADUs avoid the dimensional limitations imposed by highway transportation. We’re not restricted by maximum widths, heights, or lengths that limit prefab options. This freedom allows for more spacious rooms, higher ceilings, larger windows, and layouts that feel like real homes rather than modified trailers.
Better Long-Term Value
Site-built DADUs typically appraise at higher values than prefab alternatives because they’re considered permanent structures with quality construction equivalent to your primary home. This higher valuation provides better return on investment whether you’re refinancing, selling your property, or simply building equity.
Flexibility During Construction
Site-built construction allows for modifications during the building process if you change your mind about finishes, discover opportunities for improvements, or need to adapt to unexpected site conditions. This flexibility is impossible with prefab units manufactured off-site to fixed specifications.
Transparent Pricing and Clear Communication
We believe you deserve clear, honest pricing without hidden costs or surprise expenses. When we provide a project quote for your DADU in Bellevue, Seattle, Kirkland, Renton, Bothell, Lynnwood and Edmonds, it includes everything typically required to complete your DADU—from initial design through move-in ready completion.
What’s Included in Your Quote
Your comprehensive project price includes all architectural design and engineering services, complete permitting and regulatory approvals, full site preparation and utility connections, all construction labor and project management, quality materials throughout, interior finishes you’ve selected, appliances and fixtures, final inspections and approvals, and comprehensive cleaning and preparation for occupancy.
Understanding Potential Additional Costs
While our quotes are comprehensive, certain site-specific conditions may require additional investment. We identify these possibilities during initial property assessment and provide clear guidance about potential costs. These might include extensive site work for challenging terrain, utility upgrades required by local jurisdictions, removal of existing structures or significant vegetation, specialized foundation systems for poor soil conditions, or upgrades and premium features beyond standard selections.
We’ll never surprise you with unexpected costs. If site conditions reveal issues during construction, we communicate immediately and provide clear options before proceeding with any work that affects your budget.

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."
