What is Interactionism in Architecture?

​

In 2012, we began our research with Prof. Schoenefeldt at the School of Architecture and Planning, University of Kent, during my PhD candidature.

​

While this initial research focused primarily on Climatically Interactive Facades, it has since expanded into a broader exploration of interactive facades and user–space interaction in architecture.

​

SINTAA stands for Studio of Interactionists Associated Architects, embodying our philosophy of Interactionism and our aim of fostering interaction across all our projects. These essays provide a space for us to develop our methodology, question established ideas, and test new approaches.

​

Our research seeks to establish a retroactive theory of user–space interaction and to offer a fresh perspective on architectural history. The analysis investigates different forms of interactive facades, each comprising internal and external interactive zones, with users at the heart of these interactions. Buildings are designed to respond to human needs, enhance comfort, and establish relationships between people, space, climate, and the environment.

​

We strive to create buildings that are both sustainable and aesthetically engaging, while placing user experience at the centre of architectural design.

As we will discuss throughout this essay, the interaction between users and the external zone is just as vital as the interactions that occur within the internal zone. A building is not merely a work of art or an isolated object; it is part of a complex web of interactions between users, other buildings, and nature. These relationships extend beyond the individual building, shaping streets, cities, regions, and ultimately the environments in which we live.

If we consider a building's structure as its bones, and its mechanical and electrical systems as its veins and arteries, then the facade can be understood as its skin.

Each component is essential to the building's functionality, and all must work cohesively. The facade is particularly important because it acts as a filter between inside and outside, facilitating interaction in both directions.

​

This understanding led us to adopt the motto:

​

“Less is bone.”

​

The phrase emphasises our belief that the skin—the facade and its relationship with its surroundings—is fundamental to understanding user–building interaction.

​

Thus:

Less is bone. More is skin.
