A roof design where two roof surfaces slope downward from opposite edges toward a central valley, creating a shape resembling butterfly wings when viewed from the end. This design can collect rainwater centrally and create dramatic interior spaces.
Named for its resemblance to a butterfly's wings in profile, with the roof surfaces angling down like outstretched wings. The form gained popularity in mid-century modern architecture as architects explored dramatic angular geometries.
Butterfly roofs flip our expectations upside down - instead of shedding water to the edges, they collect it in the middle like a architectural funnel! This dramatic form was beloved by modernist architects like Marcel Breuer and Joseph Eichler for creating soaring interior spaces while making bold geometric statements.
