Entry No. 26 — the Cincinnati file — filed under: architectural oddity
Mushroom House (Terry Brown Architecture Studio)
Designed over 14 years by University of Cincinnati architecture professor Terry Brown, this organic fairy-tale structure features warped cedar shingles, irregular porthole windows, and a bright orange spiral staircase winding into a copper-sheathed cone.
The story
In the middle of Hyde Park's neat rows of traditional homes sits a building that looks less like human construction and more like a fungal outbreak. Designed over 14 years by the late University of Cincinnati architecture professor Terry Brown—who brought in his own DAAP students to help build it—the structure served as his private studio, secondary residence, and living architectural laboratory.
Brown was a devotee of organic architecture, working directly with raw, flowing materials rather than right angles. The house wraps itself in warped cedar shingles that mimic mushroom gills, punctuated by irregular porthole windows, mosaic glasswork, custom ironwork, and a bright orange spiral staircase coiling up into a copper-sheathed cone.
What it's like
Because this is a private residence, you won't be stepping inside unless you know the owner. The move here is simple: park near Hyde Park Square, grab an iced coffee, and take a casual stroll down Erie Avenue. You can view the entire exterior from the sidewalk, where you can inspect the hand-bent wood and custom glasswork up close without trespassing.
The move: Grab an iced latte from Hyde Park Square and take a sidewalk stroll down Erie Avenue to admire the intricate mosaic glasswork and bizarre geometric curves up close.
