5.0 Kerry L. Portland, OR

We started with one project with Mass Design, and were so pleased with their work that we added two additional home improvements as well. They truly care for their clients and go above and beyond when working to meet their needs. My wife and I found it surprising how carefully they listen. Things mentioned as a passing comment were noted and acted on. Their workmanship and design skills were exceptional, their communication clear and concise, and we were never left in question about any step of the process. In addition, we truly appreciated their honesty and transparency. Simply put, fantastic to work with. I would highly recommend using their services and we have more projects down the line where we will be using them.

5.0 Carol H. Portland, OR

Kimiya and Jay were a pleasure to work with in every way. Their communication was outstanding, from our first planning meeting to the clear project estimate to scheduling over the course of several weeks. They understood our needs and budget, and delivered on both. The quality of Jay's work (outdoor painting, electrical, window replacement, and finish carpentry) was top-notch. My husband and I work from home, and Jay took care to minimize any disruption and clean up thoroughly. He even resolved a persistent roof leak that two roofing companies could not find or fix. We look forward to scheduling our next projects with Mass Design Build.

5.0 Carrie U. Portland, OR

Design, build, deck, kitchen doors, walls, complete service. Excellent craftsmanship and design services.

5.0 Christina S. Portland, OR

Kimiya and Jay actually completed two projects for us. First, we wanted to add to an existing custom fence in two parts of the yard. They matched the original design perfectly and made sure the fence would be sturdy and long lasting. The work was also completed within about a week. Kimiya and Jay did a great job of talking me through the project ahead of time and getting my input. They were also willing to take on a rather small job of transforming my basement from a dim and dreary place into a light, bright, pleasant one (and on a rather tight budget). Again, we hammered out details together. The two of them are a pleasure to work with and they do an excellent job. I plan to use this company again in the near future.

5.0 Tom T. Tucson, AZ

We decided to undertake a complete home remodel to enhance our living space and modernize our home. After researching several architecture design firms, we chose Mass Design Build due to their impressive portfolio and positive reviews. Our experience with Mass Design Build was exceptional from start to finish. From our initial consultation to the final walkthrough, they demonstrated professionalism and expertise. They took the time to understand our vision and incorporated our ideas seamlessly into the design. The design team at Mass Design Build truly transformed our home. The open-concept kitchen they designed is now the heart of our home, with its sleek and functional layout. The thoughtful design choices and high-quality materials used by Mass Design Build make us confident that our remodeled home will continue to shine for years to come. Additionally, the incorporation of sustainable materials showcased their commitment to eco-friendly design. The quality of work delivered by Mass Design Build is outstanding. Every detail was meticulously executed, from the craftsmanship of the custom cabinetry to the flawless tile-work in the bathrooms. The finishes they used are not only visually appealing but also built to last. They kept us informed at every stage of the project, ensuring we were always on the same page. Mass Design Build maintained clear and open communication throughout the project. They promptly addressed our questions and concerns, fostering a strong sense of trust. The project was completed within the estimated timeframe, and we were able to move back in on schedule. The investment we made in the remodel was absolutely worth it. The results exceeded our expectations and added significant value to our home. Mass Design Build's bid came in much lower than other design firms. Mass Design Build's creative solutions exceeded our expectations, turning our vision into a reality. We wholeheartedly recommend Mass Design Build to anyone seeking a top-notch architecture design firm for their home remodel. If you're looking for a design firm that combines design expertise, creativity, professionalism, sustainability, and impeccable craftsmanship, then Mass Design Build is the choice.

Kimiya and Jay did a great job with a redo of my basement after a flood. Very personable and warm. Great job.

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.

    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.

    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
