Introducing DISPLAY: California Annex. Set in a 850 sqft storefront in Oak Park's newly developed Triangle District, DISPLAY: California Annex is a revolving pop up concept next to DISPLAY: California that connects retail with community to create amazing experiences again and again. That means brands can design and transform the space from two to ninety days. With each new brand The Annexwill completely change to create another retail experience - from installation and store design to merchandise and daily happenings - all with the intentions of exposing the possibilities that can happen when we all build together.
