Code and its image: the functions of text and visualisation in a code-based design studio

Meagher, M.; Huang, J.; Zuelzke, N.; Patt, T.; Labelle, G.; Nembrini, J. · White Rose Research Online

Traditionally, design learning in the architecture studio has taken place through a combination of individual work and joint projects. The introduction of code-based design practices in the design studio has altered this balance, introducing new models of joint authorship and new ways for individuals to contribute to co-authored projects. This paper presents…
