Allen Avenue is off the beaten path, but it shows the wealth of architectural variety in McKinley Heights; much of the neighborhood was built much later than the surrounding neighborhoods due to the presence of industrial yards.

As usual, most of the houses are actually two-family flats, disguised as single families.

I have no idea why the watermark is on the right above, but anyway, below is an example of how there are storefronts sprinkled through the neighborhood on corners.
