Dallas-based architecture firm Three has introduced a new brand identity and expanded its leadership team.

Previously known as Three Living Architecture, the firm changed its name and brand to Three to reflect the human and expressive side of architecture. The brand refocus includes a relaunch of its website, threearch.com.

The firm has also expanded its leadership team with the promotion of a long-time senior team member and the hiring of two new professionals.

Christine Cook, who has been with the firm for 25 years, has been promoted to principal. Cook will continue to lead project teams for senior communities.

The firm has also added Steven Knox as designer and senior job captain, and Catherine Wilson has been hired as a project manager.
