When the Universalist Church of Oak Park was struck by lightning and burned to the ground, Wright was asked to design a new building for the congregation.

Now Wright’s only remaining public Prairie-style building, Unity Temple came with several challenges: a $45,000 budget (one third of the cost of the neighborhood’s typical Gothic edifice), a small, narrow site on a busy main street, and the need to provide two different spaces, one for worship and one for socializing. Wright’s solution used poured-in-place reinforced concrete—a material thus far reserved for factories and warehouses—to create a church that was unlike any other house of worship before. “Why then the steeple of the little white church? Why point to heaven?” Wright asked. Instead, he would seek to build “a temple to man, appropriate to his uses as a meeting place, in which to study man himself for his God’s sake.” Wright’s choice of concrete kept costs to a minimum while enabling the façade’s ornament to be cast in, rather than applied afterwards at additional cost. To reduce the noise from the street windows were eliminated at street level. Instead, stained glass skylights and clerestories provided light to the space in green, yellow and brown tones in order to evoke the colors of nature.

Wright designed two separate high, skylit spaces—one for worship, Unity Temple, and one for the congregation’s social gatherings, Unity House—connected by a low, central entrance hall. The temple’s plan was a perfect square, creating a wonderful sense of unity and allowing up to 400 congregants to be within 40 feet of the pulpit. Surrounded on all four sides by depressed cloisters, the auditorium floor gives the visitor the sense that they are floating or on a mountaintop. This feeling imparts the space with a spiritual power that feels at once intimate and immense. Wright would later claim that building Unity Temple made him realize that the real heart of a building is its space, not its walls. In the bold simplicity of its design and the unconventional use of materials, Wright created a monumental public structure that was entirely modern in its design. For its use of a single material—reinforced concrete—Unity Temple is considered by many to be the first modern building in the world. Later in his career, Wright remarked: “Unity Temple makes an entirely new architecture—and is the first expression of it. That is my contribution to modern architecture.”
