After taking a long break from regular blog posts to deal with life issues, over the next weeks I will be posting examples of isolation facility designs from the decades just before and after 1900. These projects show the range of design strategies developed to house patients with contagious diseases safely during treatment at a time of extensive transformation of isolation practices and disease incidence. The variety of solutions can serve not only as a window into a past period of extensive design innovation, but as a prompt for today’s designers.
