The Private Home/Public Art Project features artists who use the outside of their homes and studios to exhibit work. PHP Artists have complete aesthetic control over the work and direct and immediate access to the public. The public, in turn, benefits from a diverse, intellectually invigorating streetscape. The only criteria are that the work is designed as public art, preferably site-specific, and is accessible 24/7.
