NW Build – ADU Contractor in Bellevue, WA

About NW Build

ADU and DADU Construction Services in the Puget Sound Region

NW Build specializes in the design and construction of ADUs (Accessory Dwelling Units) and DADUs (Detached Accessory Dwelling Units) throughout Bellevue and the greater Puget Sound region. Their services are aimed at homeowners looking to make better use of their property — whether that means creating a private guest suite, a space for multigenerational living, or a rental unit that generates additional income.

As an experienced ADU contractor, NW Build manages the entire process from initial planning through to the final walk-through. This includes permitting, design coordination, site preparation, foundation work, utilities, interior finishes, and more. Their approach is intended to reduce the complexity that often comes with adding a second structure or converting existing space on a residential lot.

NW Build works to ensure that each accessory dwelling unit or detached ADU integrates well with the existing home in terms of both function and appearance. Projects are designed to complement the main residence architecturally, while meeting all local building codes and zoning requirements.

What NW Build Offers as an ADU Builder

NW Build's construction services cover a range of ADU types and configurations, including:

  1. Detached ADUs — standalone backyard structures built on the same lot as the primary residence
  2. Attached ADUs — units connected to the main home, often used as in-law suites or extended family spaces
  3. Custom layouts designed to maximize usable space within the unit's footprint
  4. Full construction management from permits to final finishes

As a backyard cottage builder and granny flat builder, NW Build focuses on creating efficient, livable spaces that serve a practical purpose without compromising the overall property. Their team has working knowledge of local zoning regulations and permit processes, which helps streamline the path from concept to completed build.

Each project uses quality materials and is built with attention to structural integrity and long-term durability. NW Build aims to deliver clear communication and realistic project timelines throughout the construction process.

Serving Bellevue and the Greater Puget Sound Area

NW Build serves homeowners in Bellevue and across the broader Puget Sound region. Their focus as an ADU builder is on turning underutilized lots and spaces into functional living areas that add measurable value to a property.

Whether a homeowner is planning a detached ADU in the backyard, an attached unit for aging parents, or a rental-ready accessory dwelling unit, NW Build offers the construction expertise and local knowledge to see the project through from start to finish.

"We engaged NW Finishing, Ivan Turchik and his crew now NW Build for our master bath remodel in 2023. Each one of the men is a craftsman in his own specialty, be it tiling, plumbing, electrical work, painting, construction management or even demolition. I can honestly say that after using the bath for a year, it is my favorite room in the condo. The project was finished on time and at budget. The magnitude of the project required a complete tear down to the studs but also included a 3 week work stoppage, which Ivan and Ruvim, the construction manager, graciously built into the schedule at our request. For such a complex remodel, I advise a complete set of schematic drawings; such plans are well worth the money in that they cause you to think through all the details of the project and help avoid costly change orders and mistakes down the road. For example, we wanted to put the new shower where the old unused soaking tub was located. By the building code, tubs need only a 1.5-inch drain not the 2-inch drain required for showers. We had to revise the entire project, but thankfully while still in the planning stage. We enlarged our existing small shower that had a 2-inch drain by tearing out an existing closet. We used the tub space as a larger, better closet. By working with the NW Finishing design team, I was able to take my time to get ALL the details correct before we started construction. We went through at least a half dozen design changes. Another example, our existing electrical panel would not accommodate a new heaterfan. The NW Build electrical team solved that issue for us. We now have the best of both Icelandic and English bathrooms; a heated tile floor and a heated towel rack, without installing a new and expensive electrical panel. The electrically heated floor provides all the warmth to make our new bathroom cozy and is luxury on our bare feet. The designers also advised adding an electrical outlet for a bidet toilet seat subsequently added. The revised drawings cost a few hundred dollars instead of the thousands of dollars that change orders would have cost. A good set of drawings meant problem-free construction and left us with a room that satisfies us 100. Of course, drawings and preplanning cant answer all questions that may come up. I will add that with Ivan and Ruvim you will have hired a very experienced design and construction team. When the last-minute questions came up, I will say that 90 of the time I deferred to the contractors opinion and am super happy that I did. Sign me an extremely satisfied customer of NW Build. Hans Aschenbach, Bellevue"

"Ivan and his crew care about quality all the way down to the details. We have collaborated with him on the remodel and the renovation of our home. We appreciated how willing he was to work with us on keeping elements we liked and changing out others. Bathrooms have been refreshed with mini remodels. The kitchen was updated with a large new island, new appliances, tile, lighting, and fixtures. He's updated trim, replaced doors, improved lighting, repaired exterior elements, and more. No room has been left untouched, including the garage! Then we hired him and his crew to build us a big, new, impressive deck with all the trimmings. He is not cheap, but reasonable, and worth it for the quality and service. You know he is good because we keep coming back to Ivan!"

"We used NW Build to construct a DADU in our backyard, and had a truly enjoyable experience. NW Build provided an accurate cost estimate, gave us timely updates, and most importantly we found the team to be 100 trustworthy. They collaborated seamlessly with our interior designers, and the outcome was even better than we'd imagined. We absolutely plan to use NW Build again for future projects."

"Ivan and his team did a major kitchen expansion and renovation project for us in 2023. They provided complete designbuild services, everything from helping us envision the project to installing the final details. All throughout, they were cordial and professional. They stuck to the agreed schedule and budget. Their team were all top craftsmen and we were very impressed with the quality of their work. We've done 5 major projects over the past 6 years with different contractors, and Ivan's team did the best of all of them. We would highly recommend them to anyone looking for a quality residential job."

"NW Build recently finished a down to the studs renovation of our house including a new extension, and we couldn't be happier. We did not hire a designer, because Ivan the owner was incredibly helpful in helping us choose materials, finishes, surfaces, and even design modifications, based on his vast experience. We never missed having a designer. Ruvim the project manager ensured we started the project on time, and ran it like clockwork. We requested multiple scope changes throughout the process, including moving newly built framing, changing siding, painting scope, adding new hardscaping and more. Ivan and Ruvim were incredibly courteous and helpful and accommodated EVERYTHING, with a reasonable cost. Throughout the project they kept us apprised regularly of progress, any surprises that popped up, and walked us through choices. We never felt abandoned or taken advantage of. We even really liked their in-house crew and my wife and I both got quite friendly with them - highlights include Boris, Eugene, John, and Andrei. We were really surprised to see a consistent standard of helpfulness, customer focus and service with a smile. Halfway through the project the windocalypse hit and Ivan and crew helped us out with their generator, when we couldn't procure one. We'll never forget that. For reference our scope finally included rebuilding the floor plan, new foundation and an extension, new bathroom, flooring, cabinet-building, new siding, new HVAC splits, new deck, and much more. We have been so happy that we're planning a redesign of another floor, and we won't even get competing bids this time : I've included before and after photos of the house, I am sure you can figure out which is which :. NW Build's work has changed the look of our house completely!"
