Founder Aharon Ben Elisha has built across the Pacific Northwest since 2006. Design, permits and construction by one licensed team across King, Snohomish & Pierce County.
We keep a small book of work by choice. You get a founder who has built across the region since 2006, not a handoff to a project manager you have never met.
We know how Seattle and Eastside ADU code lands in practice, so our drawings are made to clear plan review.
Drawings, engineering, city permits and construction under one contract. One number, one answer.

About
MNBE was founded by Aharon Ben Elisha, a working Pacific Northwest builder since 2006. Framing, finish carpentry and full renovations across Seattle and the Eastside grew into a licensed design-build company delivering custom homes, ADUs and DADUs from the ground up.
We stay small on purpose. The person you meet at the consultation is the person on your job site through final inspection, with honest pricing, one accountable team and one number from concept to keys. Building across King, Snohomish and Pierce County, we stand behind every home we build.

A few excerpts from our Google reviews, from families we have built for across Seattle and the Eastside.
Most ADU/DADU projects take eight to fourteen months from first call to certificate of occupancy, including design, permitting and construction. Permitting alone typically runs three to six months in Seattle. Every client gets a written timeline up front. Construction itself takes about three to four months once the permit is issued.
Every MNBE project is bid as a fixed price contract after one free site visit and a design consultation. We do not publish per square foot pricing because every lot has its own variables. Tell us your scope, we will walk your lot, and we will come back with a written bid you can compare line by line.
We handle everything. MNBE is a full design build general contractor: drawings, structural engineering, energy code compliance, city submittals, plan-check responses and construction, all under one contract.
HB 1337, a 2023 state law, expanded ADU rights in Washington's urban growth areas. On most single family lots inside the urban growth areas of King, Snohomish & Pierce County, cities must now allow at least two ADUs, attached, detached or one of each. Critical areas, sewer access and other site conditions can limit what fits, and state law bars ADU parking requirements within half a mile walking distance of a major transit stop. We walk every client through what the law and their city's code allow on their specific lot.
We work across King, Snohomish & Pierce County: Seattle (Magnolia, Queen Anne, Ballard, Green Lake, Capitol Hill, West Seattle), the Eastside (Bellevue, Kirkland, Redmond, Mercer Island, Medina, Sammamish, Issaquah, Bothell) and the corridor north & south (Shoreline, Edmonds, Renton, Tacoma).
