Mammoth Projects

Mammoth Projects, based in Brooklyn, NY, is a New York City design-build studio specializing in high-end residential and commercial renovations across Manhattan and Brooklyn. Founded in 2013 by architectural and interior designer Maryana Grinshpun, the woman-owned firm expanded into construction in 2022 and is a licensed and insured home improvement contractor in NYC. Operating from a DUMBO studio, the team manages projects from early planning and design through construction and final closeout.

Services include full-service architectural and interior design; material and fixture specification; decor and accessories; regulatory coordination and approvals with building management, co-op and condo boards, and agencies such as the Department of Buildings, Landmarks Preservation Commission, and the Loft Board; general contracting and construction management; and post-construction support including furniture installation, TV mounting, shelving, and home care guidance. The portfolio spans pre-war co-ops, brownstones and townhouses, modern lofts and apartments, as well as offices, retail, and hospitality spaces.

Mammoth Projects emphasizes clear budgeting, scheduling, and communication, using technology to plan and track each phase. By integrating design and build under one roof, the firm provides a single point of accountability and precise execution for urban renovations.
