Interior Design

The interior design team creates unique and enriching interior spaces that support the exterior architecture of our buildings. Interior Design is a strong field where we look to create special places for people to use in the buildings. This is achieved through intelligent planning, creative problem-solving.

Fenwick Iribarren Architects are always looking to the latest interior design excellence, and also brings innovative use of materials and technology to the buildings.

The essence is to develop truly functional spaces which are enjoyed by the building users.

3D Design

Unlike most other architecture firms, Fenwick Iribarren Architects has a dedicated 3D department.

3D tools offer a powerful method of building analysis, covering the entire architectural development process. They serve both as an internal methodological procedure of the design process and enhances external communication of our ideas to clients, users, municipalities, etc., focusing on various aspects: morphological analysis, visual impact, and ambient definition.

Artificial Inteligence

To be in line with the highest level of research and development, Fenwick Iribarren Architects has created a department with use of Artificial Intelligence in order to assist the design process, creating images, and which is a true revolution to the traditional design process. IA also allows us to produce options and adjustments quickly.


Fenwick Iribarren Architects fully incorporates the BIM methodology into their design processes, from the initial idea to the construction phase. The project is conceived not as a series of disconnected documents but as a database that relates the building’s geometry and information. This provides greater control, better coordination with other disciplines, and the ability to evaluate all design aspects simultaneously, using the best tools to achieve optimal results.

Parametric Design

Fenwick Iribarren Architects currently utilizes new tools for controlled and optimized design, such as for roof geometry, stadium grandstands, or optimal facade breakdowns, among other examples.

Parametric design has become a fundamental tool in contemporary architecture, thanks to the connected digital society and advancements in computer systems and design programs. The technology allows Fenwick Iribarren Architects to develop complex stadiums geometries, both on the facades (Education City stadium) and in the Bowl (using the F- factor unique to Fenwick Iribarren Architects)
