Who designed the building?

The firm Burnham and Root designed the northern portion, and Holabird and Roche designed the southern portion.

What structural system supports the tower?

The tower relies on load-bearing masonry construction combined with a portal system of wind bracing.

Where does the structure incorporate aluminum?

Ornamental staircases inside the property feature structural aluminum.

Why does the northern exterior lack decorative projections?

The developer specified flat exterior walls to prevent soot collection and discourage birds from nesting on ledges.

What part of the city does the property occupy?

The tower stands in the south Loop district near Dearborn Street and Jackson Boulevard.

Про місце

The Monadnock stands as the tallest load-bearing masonry skyscraper ever constructed, defining the southern expansion of the Loop through unornamented brick.

Boston investors Peter and Shepherd Brooks commissioned the tower through Chicago property manager Owen Aldis following the great fire that leveled the district between the river and Lake Michigan. Brooks rejected ornamental stone carvings, directing architects Burnham and Root to produce smooth masonry elevations that would shed grime and prevent pest nesting. This insistence created a sheer brick profile.

The structure relies entirely on exterior load-bearing brick walls rather than an internal steel skeleton, which requires massive masonry piers at street level. Inside, Burnham and Root introduced internal portal wind bracing and utilized structural aluminum along the staircases. A subsequent southern addition designed by Holabird and Roche mirrored the dark exterior color while adopting conventional decorative accents.

Completion transformed the southern Loop from an edge district of cheap shacks and rail yards into a prime office district, briefly ranking the property as the world's largest commercial building. Long-term tenants navigate deep window bays and tight interior rooms constrained by load-bearing masonry rather than modern floorplates, enduring reduced interior natural light in exchange for historic central workspace.
