Twenty + Change is an organization that is primarily focused on discovering and promoting the work of young, talented architects that may not otherwise have much exposure. Keep in mind that in the world of architecture, 50 is considered young and careers don't often take off before the age of 40.
While it's been on pause for a few years, the initiative has been revived for 2021, thanks to Dubbeldam Architecture + Design and is holding an open call for submission. Head on over here for the full list of eligibility requirements and submission guidelines.
