In Seattle, an accessory dwelling unit opens quiet new rooms for family, work, and income without leaving the place that already holds memory.
Who We Are
Da Vinci Design Build works with homeowners who want more from the land they already own. The team designs and builds accessory dwelling units that respect the scale of Seattle neighborhoods, the constraints of existing lots, and the daily rhythms of the people who will live in them. Experience with local codes, careful material choices, and steady attention to detail shape every project.
What We Offer / Product Features
The company constructs detached cottages, attached suites, and garage conversions that meet current Washington standards. Options include flexible floor plans for one or two bedrooms, efficient kitchens, private entrances, and durable finishes suited to the Pacific Northwest climate. Each unit can be finished as a rental, a quiet workspace, or living space for parents or adult children. Energy-conscious systems and thoughtful site placement reduce long-term costs while preserving outdoor space.
When It’s Useful
An accessory dwelling unit serves well when a household wants steady rental income from a property that already sits in a strong market. It suits multi-generational living when parents or grown children need privacy yet remain close. It fits the need for a dedicated home office that stays separate from daily family traffic. It also works when a homeowner seeks to add value before selling or simply to create a calm guest suite that can later convert to income.
Why Choose Us
The firm understands Seattle’s permitting paths and the practical limits of hillside lots, narrow setbacks, and older foundations. Designs stay proportional to the main house rather than competing with it. Construction schedules respect neighbors and weather windows. The same team stays with a project from early drawings through final inspection, so decisions remain coherent and the finished unit feels intentional rather than added on.
