in Kirkland, WA
A premium 800 sq ft attached ADU (AADU) with its own private entrance in Kirkland, WA. Polished porcelain tile floors throughout create a luxury feel. The kitchen features high-gloss flat-panel cabinets with a waterfall island. Two bedrooms with full utility separation from the main home. Built by Evercrest LLC for $335,000 ($419/sq ft).
Exterior — Front Entrance
Brick exterior matching the main home. Prominent front window and dedicated entrance with porch. The ADU reads as a natural extension of the property, not an afterthought.
Landscaped lawn provides private outdoor space. Full utility separation means the ADU functions as a completely independent living unit.
Private Entrance
Modern entry door with horizontal glass inserts and full-height sidelite — floods the entry with natural light while maintaining privacy.
Brick surround with security lighting. The separate entrance is critical for an attached ADU — gives residents true independence.

The polished porcelain tile runs seamlessly from entry through kitchen to living — no transitions, no thresholds. Recessed lighting throughout.
Bathroom
Frameless glass shower with porcelain tile surround and hand shower. Floating vanity with undermount sink keeps the floor visible, making the space feel larger.
Full-height tile, framed mirror, chrome fixtures. The bathroom continues the premium palette found throughout.

Understanding Attached ADUs in Kirkland
An attached ADU shares a wall with the main home but functions independently with its own entrance, kitchen, bathroom, and utility meters. Kirkland allows attached ADUs (AADUs) on most residential lots. With full utility separation, it can be rented, used for family, or serve as a home office. Evercrest LLC builds both attached ADUs (AADUs) and detached ADUs (DADUs/backyard cottages) throughout the Eastside.
