Hideo Sasaki founded this interdisciplinary design practice in 1953, and it still combines architecture, landscape architecture, planning and urban design, interiors, civil engineering and graphic design under one roof. That mix is the point: campus, waterfront and district projects rarely divide cleanly between buildings and the ground they sit on. Around 300 people work from Boston, Brooklyn, Denver, Los Angeles and Shanghai. Sasaki moved its headquarters from a former Watertown mill, its home since the 1960s, into 64,000 square feet at 110 Chauncy Street in downtown Boston. The firm is master planner for the district around the new San Antonio Spurs arena, working with local landscape architecture studio MP Studio on a project team named in August 2026.
Seven disciplines make up the practice: architecture, interior design, planning and urban design, space planning, landscape architecture, civil engineering and graphic design. Around those sits a second layer the firm calls interdisciplinary expertise — sustainability, resilience, ecology, community engagement, data and design tools, a fabrication studio, research and inclusive design — which is how a campus plan ends up carrying an ecology brief and a data model rather than just drawings.
Client sectors are education, civic, arts and culture, commercial development, corporate and office, sports and recreation, and science and technology. Recent work spans a resilience plan protecting the Boston Children’s Museum from sea level rise, the Denver Broncos stadium district master plan turning the former Burnham Yard rail land into a public destination, the Fenway Corners master plan aimed at giving that Boston neighbourhood a public heart, and the Racquet and Recreation Fieldhouse at Princeton. Three projects took 2026 SCUP Excellence Awards: the Rice University Campus Framework Plan, the Baylor University Memorial to Enslaved Persons and the University of Pittsburgh Campus Master Plan. A decade-long urban regeneration plan for Tecnologico de Monterrey reshaped the neighbourhoods around one of Mexico’s largest universities.
The office culture is deliberately plural — over 300 people from 30 countries speaking more than 32 languages, and the firm’s stated values put listening and inclusive dialogue ahead of a single authorial vision. It argues, plainly, that no design hewn by one author beats one drawn from many. The practice has won more than 1,000 awards across seven decades and runs its own Foundation alongside the studio.
