In 1990 Schwetye Architects began what would become a diverse and successful practice providing quality services for residential and small commercial clients. In 1995 both Tyler Stephens and Michael Byrd met and worked briefly there before moving to different firms. Their two families remained close friends since that time.

Tyler went on to work for New Ground (formerly Bank Building Corporation) designing financial institutions nationwide before moving to Mackey Mitchell and Trivers. There he designed some of St. Louis' most compelling condominiums & apartments including The Crescent in Clayton; Cromwell Condominiums; 6, 23, & 31 Brighton Way; 830 Demun; Gaslight Square (Olive @ Boyle); 6 North Sarah; and Clayton Park Place.

Michael worked for PGAV and then Archimages. His work focused on health care renovations and the new Costas Cancer Center at Cardinal Glennon Children's Hospital. Soon after, he returned to work for Schwetye Architects and worked on new commercial retail buildings and services for property managers. He oversaw more than 500,000 sf of retail projects including Miso on Meramec, Goldman Promotions, and Street Legends.

In 2006 the two friends decided it was finally time to join forces. They both had strong ideas about design for urban environments and felt that combining Michael's retail experience with Tyler's lifestyle credentials would make some great architecture. In order to hit the ground running, they purchased Schwetye Architects and in June of 2007 renamed it CORE10 Architecture.

Why CORE10? In both office location and architectural philosophy, the firm sits squarely at the crossroads of the urban core. They love making architecture that brings together all of the stakeholders (neighbors, developers, and government) to create something unique for modern urban living. Now, located squarely in the city's Central West End, the firm's energy and strength is enhanced with a modern new office design ready to grow towards tomorrow.
