This architectural rendering illustrates a spacious waiting area in what appears to be a faith-based healthcare facility. The long, open lobby features multiple seating arrangements with modern white chairs and small tables, creating comfortable conversation clusters for patients and visitors. Large cylindrical pendant lights hang from the ceiling, complementing the neutral color palette of beige, cream, and light wood tones. On the left wall, there's a cross and what looks like a mission statement or religious inscription. The background shows a stone accent wall with what might be a fireplace, adding warmth to the space. To the right, a reception desk with a privacy screen welcomes visitors, while hallways with wood-framed doorways lead to clinical areas. The terrazzo-style flooring with linear inlays adds visual interest while maintaining the calm, dignified atmosphere appropriate for a healing environment.

This architectural rendering depicts a modern healthcare facility interior, focusing on a nurses' station or central hub area. The space features a contemporary design with a prominent reception desk combining cream-colored and dark wood finishes. The ceiling has a distinctive geometric soffit with integrated linear lighting. Medical staff in white coats and nursing attire are shown interacting at the desk, while the surrounding area includes multiple doorways leading to patient rooms or exam areas. The color palette uses calming sage green walls contrasted with neutral flooring in a pattern of varying tones. Wall-mounted displays and clinical equipment are visible in the background, and the overall design emphasizes efficiency while maintaining a clean, professional healthcare environment.

This architectural rendering depicts a café area within a healthcare facility, featuring a modern coffee counter with a digital menu board displaying beverage options and prices. The service counter combines white solid surfaces with a textured mosaic tile front panel and wooden accent steps. A staff member is shown serving a customer, while in the background, other visitors interact with coffee machines and equipment. The space is defined by a wood slat ceiling treatment that creates visual interest and warmth against the neutral palette. The flooring transitions from terrazzo-style in the main corridor to a darker, speckled pattern in the café zone, helping to delineate the space. Wood panel wall treatments and subtle green accent walls add warmth to the environment, creating a welcoming respite area that provides hospital visitors and staff with a comfortable place to take a break from clinical settings.

This architectural rendering shows another view of a healthcare facility interior, featuring a central reception or nurses' station with cream-colored modular desk elements. The design includes a distinctive ceiling soffit with integrated linear lighting similar to the previous image. To the left, a staff member in scrubs is using what appears to be a break area with built-in cabinetry and a microwave. A healthcare professional is seated at the desk station, while to the right is a waiting area where two patients sit in white chairs against a feature wall with a nature-inspired green graphic. The flooring combines varied neutral tones in geometric patterns, creating visual interest while maintaining a professional atmosphere. The space balances functionality with a calming environment through its thoughtful layout, soft color palette, and natural design elements.

Mercy Health engaged the BSA team to lead the emergency department expansion at Mercy Hospital South, enhancing the existing Level II Emergency Trauma Center. The project is designed to optimize patient care, expand behavioral health services, and improve access to emergency care for the surrounding community.

The expansion is guided by key principles established by a local steering team:

Foster a collaborative environment that promotes learning and innovation
Support staff wellbeing through wellness-focused, productivity-enhancing spaces
Maximize safety and efficiency through improved flow and planning
Expand behavioral health resources and integrated treatment
Prioritize patient-centered care aligned with the Mercy brand

The project includes not only the renovation and expansion of the building, but also a reimagined site plan to align with Mercy’s Master Plan vision. This includes reconfiguring traffic flow and creating dedicated parking to enhance accessibility.

Early project estimates revealed a gap between vision and budget. The team acted quickly, holding collaborative scope and budget alignment sessions to develop practical solutions and move the project forward.

Key features of the emergency department expansion include:

Operational and strategic planning to align with clinical goals
Right-sized design based on current industry standards
Multiphase renovation and expansion that maintains emergency operations
Key program elements: 6 Trauma rooms, 48 Standard Exam rooms, 9 Low-acuity Bays, 4 Triage rooms, a Discharge Lounge, and 13 Behavioral Health spaces
Integration of the Mercy brand into an acquired campus
Emphasis on future-ready infrastructure and staff-patient experience

This complex expansion represents a transformative investment in emergency and behavioral health care delivery at Mercy Hospital South.
