About Marksymov Brownstone

ADU Construction Services by Marksymov Brownstone in Seattle

Marksymov Brownstone LLC is an ADU contractor based in Seattle, offering accessory dwelling unit construction services designed to help homeowners expand their living space and increase property value. Working closely with homeowners from initial design through to project completion, they focus on delivering units that are code-compliant, functional and suited to each property's specific needs.

An accessory dwelling unit can serve a variety of purposes — providing a private space for family members, generating rental income or functioning as a dedicated home office. As an experienced ADU builder, Marksymov Brownstone manages every stage of the process, including local permits, zoning compliance and construction scheduling, aiming for a straightforward experience from concept to completion.

ADU Construction Options Available

Marksymov Brownstone offers several types of ADU conversions, each tailored to the existing structure and the homeowner's goals:

Basement Conversion: Existing lower-level space is transformed into a fully functional living unit with a private entrance, bathroom, kitchenette and living area. This approach makes use of the current structure to help manage costs, while addressing moisture control, ceiling height, lighting, insulation, HVAC, plumbing and electrical systems. It suits rental use, extended family living or long-term guest accommodation.
Garage Conversion: As a garage conversion contractor, Marksymov Brownstone converts underused garage space into comfortable living quarters that include a bedroom, bathroom, kitchen and living area. This adds usable square footage without expanding the home's footprint, with upgrades to insulation, windows, flooring, utilities and climate control.
Attic Conversion: Attic space is developed into a private upper-level unit featuring a bedroom, bathroom, kitchenette and lounge area. Structural upgrades, dormers, stair access, insulation, ventilation, skylights, HVAC integration and plumbing are all part of the process. This option preserves yard and garage areas while creating space suitable for guests, teenagers, home offices or rental use.

Each of these conversion types represents a practical way to make better use of existing space within a property, without the need to relocate or undertake a full home addition.

How the Process Works

Marksymov Brownstone follows a structured, step-by-step approach to ADU construction:

Consultation & Project Estimate: The team evaluates the property, reviews zoning requirements and discusses the homeowner's goals. A site analysis and transparent project estimate are provided at this stage.
Design & Planning: Custom ADU plans are developed to align with the client's lifestyle, property layout and budget. This includes 3D design, material selection and collaborative planning.
Permitting & Approvals: Marksymov Brownstone handles all paperwork, permits and city approvals, ensuring full compliance with Seattle's regulations. Their familiarity with local codes helps reduce delays during this stage.
Construction Phase: The construction team manages the full build from foundation to final finishes, using quality materials and maintaining clear progress communication throughout.
Final Walkthrough: A detailed walkthrough is conducted with the client to inspect every aspect of the completed ADU before handover.

Beyond ADU construction, Marksymov Brownstone also offers complementary home renovation services including basement remodeling, attic conversion and garage conversion, providing homeowners with the option to work with a single team across multiple projects.

The company is fully licensed and insured, and all ADU projects are completed in compliance with Seattle's building, electrical, plumbing and zoning requirements. Their experience with local regulations across areas such as Seattle, Bellevue and Kirkland makes them a practical choice for homeowners navigating the permitting process.

"Ihor and his team have done a great job on our condo remodel! The main elements of our project involved gutting two dated bathrooms and removing an old wood burning fireplace in our living room, and painting our whole condo. Before we hired Ihor's company we had a contractor who had signed on and cancelled on the project just a few months before it was to start. We fortunately found Ihor who was willing to take on our project and start on it in the same timeframe as we had originally planned. Also, Ihor's quote for our project was very competitive compared to some others we received. Ihor and his entire team are very professional, courteous, respectful and reliable. Ihor always makes himself available when you need to talk with him or want to meet in person to discuss aspects of the project. When there is an issue he makes sure to address it so that his customer is happy with the outcome. I can tell that this is important to him. He understands that his customers are putting in their savings into doing a remodel and so is empathetic to their needs. To me this was reassuring. The tile work in both our bathrooms has turned out great! We love our walk in showers and heated floors in both bathrooms. We also upgraded our electrical panel, installed some new lights and updated all our outlets to newer ones and the team did a good job with this. Finally the paint job turned out very well too. Based on my experience with Ihor, I would highly recommend him and his team."

"I cannot recommend Ihor and his team highly enough. From start to finish, they exceeded our expectations in every way. Ihor was always reliable, responsive, and genuinely invested in making sure we were happy with the progress. Any time an issue aroseor even if there was something we simply werent fully satisfied withhe addressed it immediately and thoughtfully. It was clear throughout the entire project that he stands firmly behind his work and cares deeply about the quality he delivers. Communication was seamless. I never once felt unable to reach Ihor; he consistently answered calls and texts and made himself available whenever we needed him. His entire team was equally impressiveprofessional, respectful, and truly a pleasure to work with. This was not an easy project, and we had our fair share of scope changes along the way. Despite that, Ihor and his team handled everything with patience, flexibility, and a commitment to doing things the right way. They dont disappear, they dont cut corners, and they dont make excusesqualities that, sadly, arent always guaranteed in this industry. Instead, they show up, follow through, and ensure their clients are fully satisfied. The experience was so positive that were already thinking ahead to our next project with them: remodeling all of our bathrooms. Knowing how dedicated they are to their craft gives us complete confidence in choosing them again. If youre looking for a contractor who is trustworthy, communicative, and genuinely dedicated to high-quality work, Ihor and his team are an exceptional choice."

"We hired Maksymov Brownstown to do a heavy kitchen remodel earlier in 2025. We fielded multiple quotes from various groups, and honestly Ihor was the most honest and straight forward bid that we got. We engaged with his group in March of 2025, and started breaking ground around early September. Overall, every modification and renovation made by his group was fantastic. They were very fast, efficient, and incredibly clean. Before starting anything they would put up full enclosures to try and reduce as much debris as possible, and in any instances where dustdebris escaped the plastic barriers, Ihor brought in cleaning crews to try and keep our living areas as nice as possible through-out, which felt like extra attention and care during a really stressful transition for our family. Not only did the crew pay attention to every detail along the way, they helped us with all aspects of the design phase. They were helpful when we asked for it, but took creative input when we had it. We had numerous sessions with their designers, and landed on a design proposal that we were very happy with, and Im stoked to say that the kitchen we got was nearly identical to the kitchen originally pitched in the design docs, which I feel is quite rare. We had a huge amount of creative control on what we wanted with our kitchen space colors, tiles, patterns, stains, paint, all of it, and Ihors team was very patient and worked with us on each step of the way, designing exactly what we wanted to the best of their abilities. Our kitchen remodel had a rough timeline of being done before Thanksgiving started Sept 1., and they absolutely delivered. Ihors team passed the kitchen over to me in time to cook an absolute banger of a Thanksgiving dinner, and this kitchen exceeded every expectation I had for it. Im beyond pleased with the end result. When Ive been told about remodels Ive always been told to double both the time and the estimate for a more realistic view of what the renovation is going to take to complete, however with Ihor and his crew the financial estimate was basically exactly what was quoted. We had a few small additions from our end, which caused the price to go up in expected ways, but I was truly impressed at how accurate the initial quotes were Id recommend Maksymov Brownstone for any home remodel at this point, not just kitchen. Were already investigating other remodel opportunities with this team, as they were so wonderful to work with. Their pricing is incredibly fair and beat out all the competitive offers we had, their time estimates are largely accurate, and Ihor is an absolute delight to work with. The craftsmanship is beyond comparison. Every crew that Ihor brought to our house delivered a top-notch level of quality, and Im looking forward to future engagements with his team!"

"We hired Maksymov Brownstone LLC for a full remodel of our older house. It has been four months since we are living in the house, and we are pleased with the results. Ihor, the owner, was responsive and easy to work with throughout the process. This was our first time undertaking such a large project, and Ihor patiently explained the details to us. He provided us with clear options to choose from in critical areas like the kitchen, flooring, and walls, which helped us make decisions. He gave us data and ample time to make decisions. That time and information made it easy to work with him. He was also accommodating when we had unplanned changes along the way sometimes at an additional cost. Overall, we had a great experience working with Ihor and his company and would recommend them."

"Were so pleased with our completely remodeled kitchen and are glad we selected Ihor and his expert team during the bidding process. From the very beginning we could tell Ihor was the most operationally organized vs. others just through the way he communicated; hes very structured. This is not a pushy company to work with - they will lay out options and will partner with you to execute on the vision you have for your home. They offer design and architectural services if you yourself dont have a finalized design. Its a full service shop. The price for the level of design, service, craftsmanship and detail you experience is well worth it. We went with custom cabinetry and are still in awe of how perfect everything has lined up. The invoicing process is clear, well-scheduled, and we didnt have any surprise or phantom costs. Ihor will let you know if the material you chose will be an added cost and help you navigate choices. At the end of each work day the team did a fantastic job of cleaning up the work area so it wasnt unbearable to look at or live in. The plumber on the team, Fernando, even came and solved a separate issue for us and Ihors team patched up the damage. A very professional outfit across every part of the team. If you are on the fence about working with this company, even if another company is luring you with a slightly lower price, I highly, highly recommend you choose Maksymov if you want it done without stress and for the best possible finished product."
