Building Overview
Constructed in 1936, the building was used for the classification and standardization of cotton and tobacco until 2007. After years of vacancy, the building’s rich history was restored through an adaptive reuse of the structure and a 13-story tower featuring modern and unique amenities was added.
Quote from the Architect
“Annex on 12th isn’t just a place to live, it’s a piece of history reimagined for the future. We transformed a vacant office into a vibrant community. The project honors the rich history while preserving architectural elements that enhance its connection to the neighborhood.”
-Eric Wohnsigl
