Our early involvement helps eliminate surprises. We review architectural plans, anticipate challenges, and provide transparent cost and timeline projections before work begins—setting every project up for success.
Tumen’s process keeps designers, architects, and clients aligned at every step. We oversee schedules, trades, and site logistics with meticulous attention to detail, ensuring flawless execution from start to finish.
01
We start with a detailed site visit to understand your goals, scope, and design intent. Whether you come through a designer or directly, this stage ensures we capture every nuance before plans are finalized.
02
Once architectural drawings are ready, our team reviews logistics, permits, and budgets to prevent surprises later on. Transparent estimates and schedules are provided early, aligning expectations from day one.
03
From framing to final finishes, our craftsmen execute with precision and care. We coordinate all trades, maintain clear communication, and ensure every element aligns with the designer’s vision and client’s standards.
“Aaron and team are great. They remodelled both of our bathrooms. Everyone who worked on our projects went above and beyond from communications to problem solving to staying within budget. The team of Mr Wu, Tommy, and Jason worked tirelessly. And they cleaned up after each work day! They were all very professional and courteous. I highly recommend Tumen and would definitely use them for our future projects.”

“Tumen Inc. were recommended to us by a friend after they remodeled his kitchen. We have two small bathrooms in our Bronx apartment that were both in rough shape. Tumen’s head-honcho Aaron came by our apartment with one of his contractors and they looked the situation over. Within a few days we were given a very reasonable estimate, and decided to engage them for the job. We have been very glad we did so ever since.”
Ben J.
“I cannot recommend Aaron Choi of Tumen Inc highly enough for the exceptional work he did in building my surgical office. Throughout the entirety of the job, his communication was outstanding. He was always available for my questions and concerns. He kept me informed at every step of the process, ensuring I felt involved and confident in the project. He even met me at the space after hours or on weekends when I had a concern that couldn’t wait.”
Ellie R.
“Thank you Aaron and team for such reliable and amazing work. They did a full gut and remodel of our basement in 2021. They stayed on budget and everything turned out great. We recently called for a bunch of smaller jobs we needed done inside the house. They came over Saturday looked at what we needed, gave the estimate on Sunday and he was able to squeeze us in the following week. The Job was wrapped up in less than 2 weeks.”

Ideally, we’re involved as soon as design development or architectural planning begins. Early engagement allows us to assess feasibility, flag structural or logistical challenges, provide accurate commercial pricing, and streamline the handoff into construction.
Nearly all of our commercial projects are done in partnership with architects, designers, or engineering teams. We serve as the execution arm—ensuring the design intent is built accurately, safely, and on schedule. We also work directly with business owners when a design team is already established.
We specialize in commercial interiors such as medical offices, surgical suites, retail spaces, showrooms, professional offices, wellness facilities, and other design-driven environments. We generally do not take on small cosmetic updates or low-budget tenant improvements.
Yes. We manage all relevant permits, DOB filings, inspections, and regulatory requirements. Our team is experienced with the approvals process for commercial spaces—including medical, retail, and specialty-use environments.
Through structured pre-construction planning, transparent estimating, trade coordination, and a strict no-surprise policy. We communicate closely with architects, designers, and business owners to maintain clarity on timelines, budget impacts, and weekly progress.
