The Story

A modern Magnolia detached ADU.

Magnolia is one of Seattle's most desirable residential neighborhoods. The lots are tight, the trees are mature, and the design expectations are high. A DADU on a Magnolia lot has to thread the needle between code required setbacks, neighborhood character, and the homeowner's design vision.

This Magnolia DADU is complete. The structure is sided, painted, and finished inside and out: a full kitchen with quartz backsplash, a spa shower with a pebble stone pan, epoxy finished floors, and a gravel fire pit lounge with built-in planter boxes behind the finished fence. The full reveal is below.

Construction sequencing followed the standard MNBE phases: foundation engineered to the lot's specific soils, two by six framing with continuous exterior insulation, a mini split heat pump for heating and cooling, a full kitchen and bath, and a clean, code compliant handover when finished.

Aharon supervised the project from foundation through final inspection.

June 2026

We recently completed a DADU construction project in Seattle with MNBE Construction and Development LLC, and we couldn't be happier with the results.

From the very beginning, Aharon was available, responsive, and attentive to every detail. Even before we signed a contract, he took the time to answer questions, provide guidance, and offer valuable ideas that significantly improved the project.

His experience, creativity, and problem-solving skills made a huge difference throughout the project. The workmanship was excellent, communication was clear, and the entire process was handled professionally from start to finish.

We are extremely satisfied with our new DADU and highly recommend MNBE Construction and Development LLC to anyone looking for a reliable and knowledgeable contractor in the Seattle area. 5 stars!
