IDSR is a licensed architecture practice located in the Lower East side of New York City. This website is an overview of our work. A look back at what is there, work in progress, and anticipation of projects to come. As an overview, the projects show our interest in cultural spaces, installations, and private homes. Over time, a pattern of important issues has emerged from these designs that express a consistent set of values associated with our work:

  • Working in urban settings requires a specific response to social context and the historical conditions of the built environment.
  • Working in cultural or art related environments architectural design doesn’t need to call attention to itself.
  • Working in natural settings, calls for building performance intertwined with natural elements and climate conditions, becomes the basis for dwelling.
  • Working sustainably requires understanding where architectural design converges with the practical realities of intelligent construction. We want our design to be durable, efficient, and comfortable.

Our practice includes teaching drawing and design to students of architecture. Our approach to teaching, design, and building is driven by a process of discovery. Each project we take on has the potential to develop our knowledge of building practices, material strategies, and the live-ability of environments we create.

Established in 1999, IDSR architecture is led by Maria Ibañez de Sendadiano and Todd Rouhe. We are a full-service architectural and interior design studio. Our office works on projects of any scale, from master plans to interiors; from freestanding dwellings to furniture. Regardless of the scale, the office engages each project with a comprehensive approach to schematic design, design development, and construction administration. The work of Ibañez de Sendadiano and Rouhe has been featured in numerous publications, including Dwell Magazine, Enki, and the New York Times.


Maria Ibañez De Sendadiano

Maria Ibañez de Sendadiano is a Registered Architect in the State of New York who has been practicing architecture for more than 25 years. Maria brings a hands-on design approach along with technical expertise to our design projects. Her knowledge of Passive House systems — both material and mechanical — can be seen in several past and current projects. Our clients trust Maria to deliver well-crafted projects where aesthetic decisions are connected to building performance.

Maria is an Adjunct Professor in the Department of Art History & Urban Design and Architecture Studies at NYU. She received her undergraduate Architecture degree from the University of Florida and her Graduate degree from Princeton University.

Todd Rouhe

Todd Rouhe is a Registered Architect in the State of New York with more than 2 decades of experience in California and New York. Todd’s talent lies in transforming spatial concepts into built forms. He believes that each project is an opportunity to discover something new about architecture through collaboration with clients and consultants. Todd is often partner in charge of Cultural Projects and exhibition installations working with gallerists and curators to envision new spatial identities for arts organizations.

Todd is an Adjunct Professor of Architecture in the Columbia and Barnard Undergraduate Architecture Program and Unit Chair of the Barnard Contingent Faculty Union. Rouhe received his undergraduate degree from the Southern California Institute of Architecture and his graduate degree in architecture from Columbia University.
