Tumen specializes in transforming New York City homes with craftsmanship, precision, and lasting beauty. From historic brownstones to modern apartments, our residential projects are built on collaboration with designers and a deep respect for architectural integrity.
We restore and reimagine New York’s iconic brownstones—preserving their historic charm while delivering modern comfort, functionality, and detail-driven quality.
We elevate high-rise living with precision-built interiors, refined finishes, and seamless coordination with building management and design teams.
From full-gut remodels to carefully planned upgrades, our team brings structure, clarity, and craftsmanship to every home we touch.
01
Every project begins with a conversation. We meet on-site to understand the design intent, scope, and logistics. This step ensures alignment between the client, designer, and our construction team before plans are finalized.
02
Once architectural drawings are complete, we analyze every detail—permits, materials, access, and sequencing—to anticipate challenges early. Our transparent proposals eliminate surprises and protect both budgets and timelines.
03
Our craftsmen bring each space to life with precision and care. We maintain clear communication throughout the build, coordinate with design partners, and deliver a finished product that embodies both beauty and integrity.
“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.”

“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.”

“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.”
