A real MNBE project: a backyard ADU in Bellevue we designed, permitted and built — from the first site walk to the finished keys.
About
MNBE was founded by Aharon Ben Elisha, a working Pacific Northwest builder since 2006. What began with framing, finish carpentry and full home renovations across Seattle and the Eastside has grown into a licensed design build company trusted to deliver custom homes, ADUs and DADUs from the ground up.
From the start, our vision has been simple: build homes the way we would build our own, with honest pricing, meticulous craftsmanship and one accountable team from concept to keys. We deliberately stay small and focused, so the person you meet at the consultation is the person on your job site through final inspection.
We know your home is more than a building. It is where your family grows, where memories are made, and where your equity lives. That is why we treat every project, whether a new custom home, a backyard cottage, or a permit-ready set of plans, with the same care, transparency and respect for your budget and timeline.
As we continue to grow across King, Snohomish & Pierce County, we promise never to lose sight of what got us here: doing right by our clients, standing behind our work, and building lasting relationships one home at a time.

Answering your questions about custom homes, ADUs & permits in Seattle.
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, slightly faster on the Eastside. Every client gets a written timeline up front. We do not quote ninety day fantasies.
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 We do not publish per square foot pricing because every lot has its own variables.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 (effective 2024) expanded ADU rights statewide. On nearly every single family zoned property across King, Snohomish & Pierce County you can now build at least two ADUs, with reduced setbacks and no off street parking requirement within a half mile of frequent transit. We walk every client through what HB 1337 allows 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).
