Design Build Contractors
Mammoth is a design-build company.
Designed and built for renovating, in New York City.
We’re a woman-owned and run design-build firm, specializing in renovations. We met in Architecture School nearly two decades ago, and gained valuable experience in the fast-paced New York City design and construction scenes. We leveraged this experience to develop a more thoughtful and efficient process tailored for the urban renovation market. We utilize technology for planning, budgeting, design, and communication to achieve clarity and precision at each step of the way.
Our studio is located in Dumbo, Brooklyn, and we work on projects mostly in Manhattan and Brooklyn.
