City of Tallinn has been discussing and testing temporary uses for their Baltic Urban Lab Pilot Site, located in the UNESCO protected area called Skoone Bastion. As temporary uses tend to vary widely in their purpose and duration - their viability depends on the local market and regulatory conditions in addition to the work of entrepreneurial project initiators and their supporters. Common temporary projects include community gardens and other green spaces, special events such as festivals or concert series, and stores or restaurants.The experimentation and reversibility afforded by temporary use practices can encourage a multilayered approach to land use and increase the likelihood that a vacant space will eventually find permanent use.
