The Ghost Architectural Laboratory is the research facility of MacKay-Lyons Sweetapple Architects Limited. It is an education initiative designed to promote the transfer of architectural knowledge through direct experience – project-based learning taught in the master-builder tradition – with emphasis on issues of landscape, material culture, and community.

Notice: Ghost Laboratory is on hiatus following the Ghost 13 Symposium "Ideas in Things", which was held in June 2011. Princeton Architectural Press is currently publishing a book about Ghost 13, titled "Local Architecture: Place, Craft, and Community". Please check back for any updates on Ghost or the book release.
