A Cozy & Functional ADU Transformation

Project Overview

Thornberg Construction built a fully independent mother-in-law suite in Woodinville, creating a spacious, modern, and private living area for multi-generational living. The homeowners wanted a comfortable, self-sufficient space with a private entrance, full kitchen, and spa-inspired bathroom while maintaining the home’s original architectural charm.

Client Goals & Challenges

The primary goal was to add a welcoming ADU (Accessory Dwelling Unit) that could serve as a long-term living space.

• Maximizing natural light in a shaded area.
• Ensuring accessibility with universal design elements.

To address these, our team incorporated light-enhancing design techniques, open-concept planning, and ample custom cabinetry.
