The Greater Accra Regional Hospital at Ridge

Accra, Ghana
An Exemplar of Sustainable Design in an Emerging Nation

The government of Ghana needed a way to provide its most populous city with quality medical care in a highly sustainable, resilient, and nurturing built environment. Knowing there would be unique socioeconomic and geographic hurdles to overcome, the government turned to our designers to devise the solution.

We were charged with creating a next-generation model of healthcare for this developing nation—one that elevated the patient and caregiver experience. Backed by the enthusiasm of the local community, the commitment of the local government, and the dedication of local doctors and nurses, we led the transformation of a small, simple, 1920s hospital into a flexible, modern facility poised for growth and expansion. Today, the healthcare facility that once treated British nationals during the pre-colonial era is now dedicated to caring for the rapidly growing regional Accra community—specifically, mothers and children.

Sustainability, beautifully simplified.

Despite immense infrastructural challenges—inconsistent access to fresh water and regular power outages, to name a few—the new Greater Accra Regional Hospital achieves superior sustainability and resilience. This required a bit of maverick thinking: whereas developed nations afford designers and building occupants access to high technology, in Ghana, we ensured high-performance with low technology and calculated, creative simplicity.

“We had to think very differently when it came to designing this hospital because of the region’s unique challenges. In Ghana, where maintaining and operating complex building systems is not necessarily easy, we had to achieve the same high performance with low technology and age-old strategies.”

—Pat Bosch, Principal, Design Director

Paying homage to Ghana's cultural heritage.

The hospital’s use of concrete, wood, and steel—all traditional Ghanaian building materials—creates a sense of timelessness of place. It proudly boasts a palette of bold colors, layers, and patterns, including a striking metal filigree that invokes the Kente cloth, a traditional African fabric weave.

Inside, a color-coded, shape-based wayfinding system ensures effortless navigation.
Rather than an electricity-powered elevator, patients are transported from one floor to the next by a covered outdoor walkable ramp.
Mother Nature always knows best.

We used everything Mother Nature had to offer to design this hospital sustainably. It provides passive cooling, natural ventilation, rainwater harvesting, solar water heating, daylight harvesting, shading, and locally sourced, light-colored exterior materials to reduce solar gain.

Easy access to the outdoors maintains a constant connection with nature and its healing power.
The hospital is the first LEED for Healthcare certified project on the African continent, having earned a Silver rating.
“Perkins&Will created a one-of-a-kind healthcare design for this facility in West Africa. The team was a creative force, proposing solutions that would work for the long-term benefit of the hospital.”
