Toshiko Mori Architect

What Toshiko Mori Architect does

Toshiko Mori Architect (TMA) is a New York-based private architectural design practice operating as Toshiko Mori Architect PLLC, founded in 1980 by Toshiko Mori. The firm delivers professional architectural services across four project categories: cultural facilities (museums, galleries, artist residencies, exhibition design), institutional buildings (libraries, university facilities, research labs, civic infrastructure), high-end residential commissions, and commercial retail interiors. Notable built work includes the Center for Maine Contemporary Art, Brooklyn Children's Museum Rooftop Pavilion, Sean Kelly Gallery, Novartis Institutes for BioMedical Research in Cambridge, Brown University's Watson Institute, Brooklyn Public Library Central Branch renovation, and the pro-bono Fass School and Thread Cultural Center in Senegal for Le Korsa and the Josef and Anni Albers Foundation.

TMA's technical differentiation is grounded in sustainable design expertise, including passive house construction with local materials, geothermal heating and cooling systems, photovoltaic integration, CNC-milled structural components, and a proprietary parametric roof inversion technique developed for the Thread Cultural Center. The firm has achieved LEED Platinum (Syracuse Center of Excellence) and LEED Gold (Brown Environment Society) certifications and has earned AIA Honor Awards in 2017 and 2021, among dozens of industry recognitions. Engineering collaborations with Arup and Schlaich Bergermann and Partners support technically demanding projects.

The firm generates revenue exclusively through project-based professional design fees, with pricing determined per engagement based on scope and complexity. It serves enterprise and institutional clients directly through relationship-driven engagement, leveraging the principal's Harvard GSD professorship, Venice Biennale exhibitions, monographs, and AD100 Hall of Fame recognition as visibility channels. The firm maintains a deliberately small team of approximately 10 architects and designers plus financial and office management, with no external investment, parent company, or acquisition activity documented. TMA has been profiled internationally across Asia, Europe, and Africa in addition to its primary Northeast US base.
