Our knowledgeable team will guide you through the process, ensuring your ADU, Dadu, JADU, or Guest House meets your expectations
Turn your property into a more flexible and valuable space with experienced ADU builders in Seattle. At Anura Design, we help homeowners design and plan fully compliant Accessory Dwelling Units (ADUs) Junior ADUs (JADUs), and Detached ADUs (DADUs) that fit Seattle’s unique zoning and building requirements.
Whether you are creating a rental unit, a backyard cottage, or space for family, our team guides you from initial feasibility through permit-ready plans.
With variations or additions in size, height, style, and price, it’s essential to make informed decisions. Buying plans online may not meet jurisdiction requirements, and even prefab structures require proper installation submittal. Understanding feasibility, requirements, and costs can be challenging. Our approach is simple: your proposed design should perfectly meet your needs. We treat each project as someone’s home, ensuring meticulous attention and care in the design process. We offer our accessory dwelling unit conversions in Seattle and other Washington areas. Contact us to see if we are available in your area.

Invest Smarter With the Right ADU Builder For a clean Design Process
When it comes to obtaining an ADU permit, having a complete set of new construction drawings is crucial. Many homeowners make costly mistakes by buying generic plans online or choosing prefab units that do not meet Seattle building requirements. Even modular and prefab ADUs still require full permit submittals, engineering, and site-specific compliance.
Adding an accessory dwelling unit in Seattle is one of the most effective ways to increase property value and generate long-term income.
Homeowners commonly use ADUs for:
- Rental income
- Housing for family members
- Home offices or studios
- Guest accommodations
With rising housing demand, ADUs and backyard cottages continue to be a smart investment across Seattle neighborhoods.
