Intermediate space. Guidelines for improving staircases in residential buildings. The main focus of the work is on the design process. The work is based on the study of staircase culture and experimentation in the space, it is about combining ordinary details to make the user aware of the design development process. Communication with the user and communication with the space. In the project, I developed guidelines for improving staircases in residential buildings, basing them on two different solutions for staircases. Showing that one principle, by varying and adapting to needs, can be applied in different stairwells.
