John Hancock Center - Design

Design

One of the most famous buildings of the structural expressionist style, the skyscraper's distinctive X-bracing exterior is actually a hint that the structure's skin is indeed part of its 'tubular system'. This is one of the architectural techniques which the architects used to achieve a record height (the tubular system is the structure that keeps the building upright during wind and earthquake loads). This X-bracing allows for both higher performance from tall structures and the ability to open up the inside floorplan. Such original features have made the John Hancock Center an architectural icon. It was pioneered by Bangladeshi-American structural civil engineer Fazlur Khan and chief architect Bruce Graham.

The interior was remodeled in 1995, adding to the lobby travertine, black granite and textured limestone surfaces. The elliptical-shaped plaza outside the building serves as a public oasis with seasonal plantings and a 12-foot (3.7 m) waterfall. A band of white lights at the top of the building is visible all over Chicago at night and changes colors for different events. For example, at Christmastime the colors are green and red. When a Chicago-area sports team goes far in the playoffs, the colors are changed to match the team's colors.

The building is a member of the World Federation of Great Towers. It has won various awards for its distinctive style, including the Distinguished Architects Twenty-five Year Award from the American Institute of Architects in May 1999.

Famous quotes containing the word design:

    Joe ... you remember I said you wouldn’t be cheated?... Nobody is really. Eventually all things work out. There’s a design in everything.
    Sidney Buchman (1902–1975)

    Humility is often only the putting on of a submissiveness by which men hope to bring other people to submit to them; it is a more calculated sort of pride, which debases itself with a design of being exalted; and though this vice transform itself into a thousand several shapes, yet the disguise is never more effectual nor more capable of deceiving the world than when concealed under a form of humility.
    François, Duc De La Rochefoucauld (1613–1680)

    I begin with a design for a hearse.
    For Christ’s sake not black—
    nor white either—and not polished!
    Let it be weathered—like a farm wagon—
    William Carlos Williams (1883–1963)
