After walking past the Monadnock Building for months, the blocky, unevenly carved letterforms above its entrances grew on me. The building itself is a precursor to both skyscrapers and post-modern architecture; throw in the fact that it was designed by John Root, one of Chicago's golden boys of architecture, and you can see it for the masterpiece it is. The quintessential Chicago attitude is reflected in the building's stone letters: stubborn, bold, and just a little rough around the edges.
In the same way that the building reflects the classic Chicago School architecture but also prefigured modern skyscrapers, the Monadnock font is modernizing a tried-and true typeface.
Following the style of the stone letterforms, the vectors of the typeface mirror enlarged images of the chiseled letters—the gritty texture of the pixels reinforcing the transitional nature of the building's influential architecture.
