A façade of green serpentine stone is a highlight of this Second Empire double house. It was built in 1879 as a rental property by W. H. Roy. He was the son-in-law of watchmaker / developer Godfried M. Zahm. Watchmaker Zahm lived here in his retirement. He was influential in the development of this Chestnut Hill neighborhood.
The mansard roof and the porch are topped with decorative iron cresting. The double wooden doors have applied medallions.
