Who We Are

Nobutaka Ashihara Architect P.C.

Since its inception in 1978, Nobutaka Ashihara Architect has been a responsive and capable firm of architects, planners, and designers offering a broad range of design, planning, and development consultation services to both domestic and international clients.

Based in New York, the firm has the ability to organize and execute both design and development projects. Commissions include institutional, commercial, and industrial buildings of various scales, interior design, renovation projects, single-family and multi-unit residential developments, as well as large-scale master planning proposals and feasibility studies.


The firm makes extensive use of computer capabilities for research, site selection, and project control whenever these services suit the needs of the client and scope of the project. A thorough understanding of client’s goals and responsiveness to their client’s requests within an acceptable financial, social, and environmental framework are primary concerns underlying all of the firm’s work.

Underlying these concerns is the firm’s commitment to the art and is apparent in its consistently high quality of design.
