'''Unity Temple''' is a [[Unitarian Universalism|Unitarian Universalist]] church building that houses the '''Unity Temple Unitarian Universalist Congregation''' at 875 [[Lake Street (Chicago)|Lake Street]] in [[Oak Park, Illinois]], United States. The structure, designed by the architect [[Frank Lloyd Wright]] in the [[Prairie style]], is cited as an early example of [[modern architecture]].<ref name="The Manchester Guardian 1939" /> The building consists of an auditorium to the north and a church house called Unity House to the south. The two sections, and an entrance pavilion between them, are all made of [[reinforced concrete]].

The [[Church (congregation)|congregation]] was formed as the '''Unity Church of Oak Park''' in 1871. It originally occupied a [[Gothic Revival architecture|Gothic Revival]] building and went through several pastors in its first two decades. Rodney Johonnot, who became the senior pastor in 1892, began planning a replacement structure in the early 1900s. After the original church burned down in 1905, the board of trustees selected a site on Lake Street and hired Wright to design a new building, Unity Temple. Wright's plans were approved in 1906 after much debate, and construction began on May 15 of that year. After various delays, Unity House opened in September 1907, and the auditorium was finished in October 1908; the church was dedicated on September 26, 1909. Over the years, the temple attracted visitors from around the U.S. and worldwide. The church was restored in the 1960s, and it gradually underwent further upgrades from the 1970s to the 2000s. Unity Temple was completely refurbished from 2015 to 2017.

The temple is decorated with abstract motifs instead of overtly religious imagery. The facade is made of [[Portland cement]], which has been washed away to expose the gravel underneath; there are recessed [[clerestory]] windows near the top. Unlike contemporary churches, Unity Temple was designed without a spire; instead, the roof consists of multiple flat, overhanging concrete slabs. The auditorium is shaped like a [[Greek cross]], with stair towers at each corner. It has two levels of seating surrounding a central [[pulpit]], in addition to clerestories and [[skylight]]s. Unity House has skylights and two balconies.

Unity Temple has received extensive architectural commentary over the years, and it has been the subject of many media works, including books and museum exhibits. Its design is credited with having helped inspire multiple architects. Unity Temple is designated as a [[National Historic Landmark]] and is part of [[The 20th-Century Architecture of Frank Lloyd Wright]], a [[World Heritage Site]].

The interior of Unity House is painted in various shades of green, yellow, and brown.<ref name="Siry p. 165" /> Unity House's primary interior space measures about {{convert|82+5/6|by|27+1/6|ft}} across, corresponding to approximately 12 by 4 units.<ref name="Siry p. 160" /> There is a square hall at the center, measuring about {{Convert|30|ft}}<ref name="McCarter2 p. 22" /> or {{Convert|33+5/6|ft}} on each side.<ref name="Siry p. 160" /> There are balconies to the west and east of the central hall, on the same story as the auditorium's lower seating level.<ref name="McCarter2 p. 22" /><ref name="Siry pp. 161–162" /> The balconies are supported by [[I-beam]]s and contain small columns with wooden [[Sconce (light fixture)|sconces]],<ref name="Siry pp. 161–162" /> in addition to railings with wood strips.<ref name="Siry p. 164" /> The columns have vertical wood strips along their shafts and horizontal wood strips at their capitals.<ref name="Siry p. 164" /> The spaces under each balcony are illuminated by spherical lamps.<ref name="Siry pp. 161–162">{{harvnb|Siry|1996|ps=.|pages=161–162 }}</ref> The balconies and the spaces beneath them were originally used as classrooms.<ref name="McCarter2 p. 22" />

There are square closets at each corner of Unity House's main room, measuring about 1 unit wide.<ref name="Siry p. 160" /> On the southern wall of the central hall is a recess with a fireplace measuring about {{Convert|13+1/6|ft}} wide;<ref name="Siry p. 160" /> this feature recalled many of Wright's residential designs, which also had central fireplaces.<ref name="Gibson e506">{{cite web |last=Gibson |first=Eleanor |date=June 12, 2017 |title=Frank Lloyd Wright's Unity Temple was the "first expression" of modern architecture |url=https://www.dezeen.com/2017/06/12/unity-temple-frank-lloyd-wright-chicago-oak-park-modern-architecture-150th-birthday/ |access-date=January 31, 2025 |website=Dezeen }}</ref> On the northern wall, there are three casement windows facing the pastor's study.<ref name="McCarter2 p. 22" />

Unity House primarily receives natural light from skylights in the ceiling.<ref name="Inland Architect 1906 e817" /> The roof [[truss]]es are supported by eight columns arranged in a 2×4 grid.<ref name="Siry p. 160" /> The ceiling is divided into rectangular [[coffer]]s measuring {{convert|15|by|4.5|ft|adj=off}} across. Each coffer has a skylight with four glass panes, which are either opaque or tinted in various shades of yellow, green, and brown.<ref name="Siry pp. 166–167" /> There are seven skylights in total, all of which are surrounded by wood strips.<ref name="Siry p. 164" /><ref name="McCarter2 p. 22" /> Rectangular and square motifs, reminiscent of the floor plans, are used in the skylights.<ref name="Siry p. 168" />

=== Mechanical features ===
Unity Temple originally had a coal-fired steam boiler, in addition to concrete ducts that were supposed to distribute heat.<ref name="AR-2006-02" /><ref name="Hampton b253" /><ref name="Sokol p. 137">{{harvnb|Sokol|2008|ps=.|page=137 }}</ref> The ducts proved ineffective at carrying air,<ref name="Sokol p. 137" /> and as such, steam radiators were installed shortly after the temple was finished.<ref name="AR-2006-02" /><ref name="Hampton b253" /><ref name="Sokol pp. 138–139" /> A hot-water system was also installed within half a year of the temple's completion; it remained in use through the 21st century.<ref name="Southern Illinoisan 2005" /> The coal-fired boiler was replaced with an oil-fired boiler in the early 20th century, and a gas generator was added later in the century.<ref name="AR-2006-02" /> Since the 2010s, the church has been heated by a [[geothermal heating]] system,<ref>{{cite web |last=Lydersen |first=Kari |date=October 15, 2018 |title=Geothermal and the city: Utilities and industry push installations in Chicago |url=https://energynews.us/2018/10/15/geothermal-and-the-city-utilities-and-industry-push-installations-in-chicago/ |access-date=January 27, 2025 |website=Energy News Network }}</ref> which consists of nine {{Convert|500|ft|4=-deep|adj=mid}} wells on the lawn just north of the church.<ref name="Johnson o698" /> This system includes ice-storage space and a set of geothermal wells.<ref name="Hampton b253" /><ref name="AR-2006-02" />
