The Harvard Graduate School of Design’s popular free online course, The Architectural Imagination, has returned for 2018, again offering anyone across the globe the opportunity to study the fundamentals of architecture from one of the world’s foremost design schools at absolutely no cost.

Led by professors Erika Naginski, Antoine Picon, and K. Michael Hays, alongside PhD student Lisa Haber-Thomson, the 10-week course will cover topics ranging from learning to “read” buildings as cultural expression to technical drawing and modeling exercises.

The course description explains:

"Architecture is one of the most complexly negotiated and globally recognized cultural practices, both as an academic subject and a professional career. Its production involves all of the technical, aesthetic, political, and economic issues at play within a given society. Over the course of ten modules, we’ll examine some of history’s most important examples that show how architecture engages, mediates, and expresses a culture’s complex aspirations.”

While the course is completely free, students can receive a verified certificate of completion for an additional $99.
