Looks like a Victorian era-wannabe barn, especially with the fishscale shingles on the facade...
In California, for instance, especially in Redlands, Eureka and Ferndale, a number of the Victorian homes displayed the date completed in the upper eaves...not to be construed as an address...
Ocassionally this also is true of post 1900's commercial and public buildings...
I've noticed this as a practice ranging from 1870's thru the 1920's...
