Illinois State Capitol Exterior Doors

Springfield, Illinois / United States of America

SPECIAL RECOGNITION

As part of the renovation of the West Wing of the Illinois Capitol, aluminum and glass entry doors dating from the 1970s were removed. For their replacement, the project team looked to the building's original exterior and interior doors for inspiration.

Because the building's original doors were vulnerable to the elements, copper-clad Mahogany doors were specified. This is a 19th century method and similar to the clad doors at the Water Tower Pumping Station in Chicago by W.W. Boyington, who it turns out was hired by the State to complete the Capitol after the death of the Capitol's original architect Alfred Piquenard in 1876. The copper wraps the edges, protecting against moisture, while the rich Mahogany is visible on the interior side. Massive hinges connect directly to steel tubes concealed within the jamb to carry the 2 ¾ inch thick leafs. Insulated and tempered glass lites are beveled to match the historic appearance. Over time, the copper cladding will patina naturally and develop a rich brown color.

Automatic operators provide full accessibility. In the event of a fire, the doors open automatically to supply make-up air to the rotunda's smoke exhaust system.
