The Kosar facility is a 178-bed, secure, residential behavioral healthcare hospital located within Twin Valley Behavioral Healthcare (TVBH). Operated by the Ohio Department of Mental Health and Addiction Services, this obsolete facility operated 24/7, 365 days per year, and it was replaced by the 208-bed 285,000 square foot facility. Patient accessible areas were designed to reflect state-of-the-art safety and security requirements, including ligature-resistant fixtures and hardware and highly durable construction. The new facility was constructed independently of the existing facility to minimize disruption of existing operations.

This facility provides a secure environment for residential patient units, clinical/admitting space, full kitchen, indoor and outdoor recreation, and required support operations consisting of administrative offices, food and bulk storage facilities and maintenance operations. Key features of this facility include the development of a “secure building envelope” for patients.
