"Notable because it is so typical"

This Federal style house (transitioning to Greek Revival) at 3811 Kosciusko in the Marine Villa neighborhood is somewhat rare in the St. Louis of today. Yes, it's still there (and appears occupied!).

But the Historic American Buildings Survey (HABS) architects and engineers had this to say of the property, circa 1940.

Survey number HABS MO-1172
Building/structure dates: 1857 initial construction
Building/structure dates: 1859 subsequent work
Significance: This 2-1/2 story, brick house, built in 1857 and 1859, is typical of the upper middle class homes of the day; notable because it is so typical.

Emphasis mine.

If only it were still true.
