One of my favorite houses in the Tower Grove Park area is the two-flat at 3511 Arsenal Street. I love its monochromatic articulation in red brick and terra cotta, and its overdone neoclassical ornamentation, suggestive of South American influences.
Last year, I watched as it was boarded up and renovated. The house had its original windows and appeared to be in good condition; it had been occupied for its whole life until then.
Unfortunately, the result of the renovation is baffling at best (what's with fake nine-over-nine windows?).
