I realise this may be more a carpentry topic, but this was the best place I could find to post this.
This was a house in Detroit called the Wilson-Mabley house, located on Edmund Street off of Woodward. It was built in the 1880s in the neo-baroque style, which was a rarity at the time. It was modeled after Le Palais des Tuileires in Paris. It was torn down in the 1960s.
As you can see, the house had a decorative balcony. The balcony appears to have been wood structure and non-occupiable (we have no clue what those boards are between the balcony posts, please feel free to offer any ideas I'd appreciate that).
Now, the only other existing photo of the house was in the 1960s and here we can see that the balcony was removed (sometime after 1921 according to Sanborn Maps). But what makes no sense is that the cornice molding continues across the entire facade! Underneath what was the balcony! Now, this house was a rooming house in the 1920s and converted to an apartment building with a massive addition on back. There was no logical reason then to preserve the house and details were stripped off on houses all around this neighborhood (this photograph suggests the entire tower roof may have been taken off). But why would there be cornice molding where there was a balcony? Why isn't there a gap?
One explanation was that the balcony was removed and the owners had the cornice molding matched to fill in the gap. But this house was a rooming house by those days and so this doesn't seem to make sense for a landlord.
The other explanation I can offer is that it was easier in those days for a mason to do his work (it appears all of the cornice molding was solid masonry) all the way across the facade then to create gaps. After his work was done, the carpenter just covered it with the balcony.
This is where I'd like to pick your brains. Has anyone seen something like this happen before? Do any of these theories make sense or is there a better theory? I know another house in the same neighborhood where this appears to have happened as well, but that is a more complicated situation. The cornice molding on the house above, the Wilson-Mabley house, remains a mystery to me. Thank you!
