Combining Styles, 2449 W. Devon and 1028 W. Chicago

Sometimes buildings change according to established patterns, like a sun-porch added to a farmhouse or a side wing on a mansion.  But less work has been done on analyzing how historic commercial buildings change over time.  In general the preservation community is focused on finding the best unaltered examples of building types.  But there are many patterns which are just as valid in understanding the history of a property, even when they're not particularly picturesque.  Take these 1-story additions to older 2-story commercial buildings.

The older portions of these buildings observe two of the eclectic styles popular in the 1920s, Classical Revial and Italian Renaissance Revival.  When the owners saw an opportunity for expansion they switched from the earlier style to new styles popular at the time.  To the right they've chosen Art Deco, using glazed terra cotta blocks with fluted bands and geometric ornament.  Below they've gone with stacked brick and permastone.  There's absolutely no concern with matching the ornamentation of the older portion, or even aligning the new storefronts with the existing geometry.  Why is that? A few thoughts:

1. The whole idea was to update the building, make it seem competitive and modern. Maintaining the original ornamentation wouldn't signal the desired excitement.

2. In the 20 years between initial construction and enlargement the entire building industry reoriented around new styles and new materials.  The more traditional architectural treatments would have required a custom approach and therefore would have been much more expensive.

3. Advertising has changed, and the creation of large sign bands takes precedent over any "nostalgic" treatment.  By extending the new storefront into and over the old portion the amount of advertising could be doubled to accomodate larger, more aggressive signage.

4. Many businesses in traditional commercial areas (Main Street) found that the space on the upper floors wasn't being utilized as intended.  Living units above commercial spaces are generally less desirable than those on quiet streets.  And despite the space added, it's still more expensive to build a two-story building.  Expanding only the commercial space on the first floor is a reasonable solution.

Interestingly, the newer portions of the buildings were both from 1940s (as far as I can tell).  Perhaps this was the last gasp of Art Deco and the first breath of 1950s Modern.

I'm on the lookout for more of these buildings which have expanded in interesting ways.  I imagine putting together a booklet titled, "Messed Up Storefronts," although that might sound a bit prejudicial.  So please email me if you know of any in your neighborhood.
