New Day Construction

New Day Construction is a family-owned, licensed and insured design-build remodeling and construction company based in Bellevue, Washington. The company specializes in custom ADUs, home additions, kitchen and bathroom remodeling, whole-home renovations, and custom home construction. It combines design, engineering, permitting, and construction under one team, making it appropriate to classify as both an ADU Builder and ADU Designer.

Its ADU services include backyard cottages, garage conversions, basement apartments, and in-law suites. The company manages the process from initial design and engineering through permitting, construction, and warranty-backed completion.

The company specifically highlights custom ADU plans and 3D renderings, along with local knowledge of zoning, permitting, and building requirements in the Seattle Eastside.
