Brutalist
http://www.ontarioarchitecture.com/Brutalist.htm
The Weldon Library at the University of Western Ontario is typical of Brutalist architecture. The rounded corner stair towers provide end balance for five horizontal bands of béton brut concrete. The only ornament are three vertical "stripes" in the concrete.
The lower levels have a variety of box-like forms projecting along an irregular plan, all in windowless poured concrete. The door is simple and not a focal point of the design. The door surround is functional with no historicizing detail. The interior surfaces of the building are also poured concrete.
