Form and Function

Inseparable Relationship: Kahn believed that form and function are inseparable, with each informing the other in the design process. He argued that the form of a building should evolve from its intended function, leading to spaces that are both beautiful and purposeful.

Servant and Served Spaces: He introduced the concept of ‘servant’ and ‘served’ spaces, where ‘servant’ spaces contain the supporting elements like stairwells and elevators, and ‘served’ spaces are the primary use areas like rooms and halls. This distinction helped organize buildings in a way that was intuitive and efficient.

The Use of Light

Natural Light as a Material: Kahn often referred to natural light as his favorite material. He masterfully manipulated light to define and animate spaces, creating dramatic effects and enhancing the spiritual quality of his buildings.

Light and Shadow: He was fascinated by the interplay of light and shadow and used it to give depth and texture to surfaces, making the architecture feel alive and dynamic.

Material Authenticity

Honest Use of Materials: Kahn advocated for the honest use of materials, allowing their natural texture, color, and strength to be expressed. He often exposed structural elements and used materials like concrete, brick, and wood in their most natural form, celebrating their inherent beauty.

Structural Integrity: He emphasized structural integrity and clarity, where the construction method and materials were integral to the design, contributing to the overall aesthetic and thematic expression of the building.

Spaces for Social Interaction

Communal Spaces: Kahn placed great importance on creating spaces that foster social interaction and community building. He designed gathering areas that were inviting and human-scaled, encouraging people to come together and engage with each other and the architecture.

Integration with the Environment: His designs often featured outdoor and indoor spaces that flowed seamlessly into one another, blurring the lines between the built and natural environments and promoting a sense of openness and connectivity.

Architectural Experience

Sensory Engagement: Kahn believed that architecture should engage all the senses, creating an experience that is not only visual but also tactile and even auditory, with considerations for the acoustics and the feel of materials.

Timelessness: He sought to create buildings that were timeless, transcending current trends and styles. His architecture aimed to touch on universal human values and needs, ensuring relevance and resonance across different eras.
