Mammoth Projects

What Mammoth Projects does

Mammoth Projects is a New York City design-build studio founded in 2012 that delivers architectural design, interior design, project management, and general contracting under a single integrated engagement. The firm is woman-owned and led by co-founders Jessica Maktal and Maryana Grinshpun and operates out of 55 Washington Street, Suite 303 in Brooklyn, NY. It serves clients undertaking high-end residential gut renovations — pre-war co-ops, brownstones, townhouses, and lofts — and commercial fit-outs across Manhattan and Brooklyn, with technical capabilities spanning custom millwork, bespoke cabinetry, in-house furniture fabrication, NYC Department of Buildings permitting, co-op board approvals, and landmark-compliance work.

The firm's core delivery model is integrated design-build, meaning in-house designers, project managers, and construction trades collaborate from concept through punchlist, removing handoffs between separate architects, interior designers, and general contractors. Project types range from individual residential gut renovations to large commercial jobs such as the approximately 25,000 sq. ft. Nuts.com warehouse-and-office buildout and the 2,200 sq. ft. Field Guide farm-to-table restaurant, the latter delivered in roughly four months and earning a Dezeen feature in May 2025. The company is listed in the Architectural Digest Pro Directory (2025), carries a 5.0 rating across 23 reviews, and has been profiled by The New York Times, Architectural Digest, Dezeen, and Frame Magazine.

Revenue is generated on a project-by-project basis via custom quotes rather than disclosed pricing tiers, with design soft costs per engagement cited in the $20,000–$40,000+ range and permitting approximately $15,000 per project on the residential side. Commercial contract values are materially larger and are not publicly itemized. The go-to-market motion is enterprise field sales combined with content marketing (SEO-driven blog content on topics such as NYC permitting timelines, co-op renovations, and brownstone gut renovations) and earned media in design and lifestyle publications, with new business routed via [email protected].
