Integrating computational technology to architectural surfaces challenges the traditional design process offering novel possibilities to design materials and spaces. Starting with a conceptual design exercise, the present paper discusses the relation between form, textile expression and human interaction in architectural design by joining together different design practices such as architecture, textile and interaction design. The aim of the paper is to challenge design views and to integrate textiles and computerized technology as part of the expression in space design that means to relate the aesthetic of the space to the user’s actions. It is a reflection on the role of interactive textiles textures that exceed the expressional and technological limits of the traditional textile materials having dual nature between function and ornamentation in architectural design. The present paper is an example of practice based research and follows a design project that had as objective to design a collection of interactive textile structures meant to be used in an architectural context. The aim of the project was to explore the soft face of computerized technology and to integrate it into the space design to generate new typologies that relate the space to the human presence; to explore situations how people’s relation to the space materializes and progresses in time by the mean of interactive soft surfaces.
