The Architecture Foundation recently launched their annual international Open Call for innovative independent exhibitions and installations for its central London Project Space. Intended as an incubator for independent positions and architectural experimentation, projects selected through the Open Call will punctuate the AF’s ongoing curated program. This program, competitively selected through a jury process, will give space to individuals or organizations to activate the AF Project Space as a testing ground for modes of exhibition and 1:1 scale spatial experimentation, an open studio, a public residency or other diverse formats. The foundation's recent initiative, 'We Made That', was a project selected through the 2012 Open Call. The deadline for submissions is May 10. For more information, please visit here.
