Green House Project rebuilt nursing homes as small houses

Traditional American nursing homes had converged on essentially the same architecture for decades: a hospital-shaped building organized around a central nursing station, long corridors of numbered rooms, and one shared dining hall serving 100 or more residents at fixed times. The industry treated this design as a solved, efficiency-optimized layout and directed improvement efforts entirely at staffing ratios, training and clinical protocol — the building itself was never treated as a variable in resident health outcomes.

Geriatrician William H. Thomas, who had already developed the 'Eden Alternative' — introducing plants, animals and children into existing institutional nursing homes to reduce the sense of confinement — concluded the underlying building shape was itself working against the outcomes everyone was trying to protocol their way toward.

Rebuilt facilities as small houses of 10 to 12 residents, no central station or corridor, making the building's design the variable instead of working around it.

The hospital-style corridor and central nursing station created institutional routines that harmed residents.

Small houses with kitchens and dining tables gave residents control over daily schedules, improving well-being.

Cross-trained staff in each house provided integrated care, reducing the need for separate departments.

Physical redesign addressed root spatial causes, leading to better clinical outcomes at comparable cost.

Before adding protocols, check if the physical layout itself is causing the problem; redesigning space can outperform procedural fixes.

A longitudinal comparison (Kane et al., 2007) of Green House residents against matched traditional nursing-home residents under the same ownership found Green House elders were 45% less likely to need urinary catheters, 38% less likely to develop bedsores, and 16% less likely to become bedridden, alongside fewer hospital readmissions — better clinical outcomes achieved through building design and staffing structure rather than added clinical protocol, at comparable operating cost.
