The Tiffany Glass Building, originally the Citizens Building is a high-rise office and retail building located at 840 Euclid Avenue in Cleveland, Ohio, in the United States. The structure was built in 1903 by the Citizens Savings and Trust, a local bank. Its entrance portico was removed in 1924, and a two-story addition erected in its place. Home to the City Club of Cleveland since 1982, the building was renamed the City Club Building in 1999, and renamed again to its current name in 2024.

Construction Start of the project In September 1899, Citizens Savings and Trust purchased a lot and two-story building located at 850 Euclid Avenue in Cleveland, Ohio. The property was owned by the city of Cleveland, which had purchased it in 1854. The structure had originally been a high school, although more recently the first floor had served as the headquarters of the Cleveland public schools and second as the main branch of the Cleveland Public Library. Citizens purchased the land and building at auction for $310,000. Five months later, Citizens announced the selection of the local architectural firm of Hubbell & Benes as the architect of their new headquarters building. Hubbell & Benes proposed a 13-story, steel frame structure whose lower floors would be clad in granite and the upper floors in either brick or terra cotta.

By summer 1900, plans for the new building were complete. It was planned for 14 stories (), which included a below-ground level. The building was to have a frontage on Euclid Avenue of and on Oak Street (now E. 8th Street). In addition to the main entrance on Euclid Avenue, there was a secondary entrance on Oak. The facade of the first two floors would be clad in Barre Granite, with the upper floors in brick and ivory colored, glazed terra cotta. A granite portico supported by four Doric columns, each high and in diameter, masked the Euclid Avenue entrance. On the left (east) of the bank entrance was a door leading to a foyer and access to the offices on the third through thirteenth floors. This was balanced visually by the addition of a double window to the right (west). The main entrance led into a lobby wide and deep, with a skylight overhead providing natural light. The lobby led to the main banking room, which was deep and high. To the right (west) of the lobby was the a women's banking parlor; to the left (east), a foyer which provided elevator and staircase access to the upper floors. Paralleling the main banking room on the east and west were separate halls, each wide and deep. On the left (east) was the safe deposit banking parlor, with the vault containing the safe deposit boxes located at the rear (south). On the right (west) was the bank's clerical department. Initial estimates of the cost of construction were $1.2 to $1.5 million ($ to $ in dollars).

Hubbell & Benes also designed the decorative interior scheme of the building. The public hallways on every floor of the building had marble floors and walls. Muralist Edwin Blashfield, muralist Kenyon Cox, and Tiffany & Co. were commissioned to do work for the lobby. McNulty Brothers of Chicago designed and executed the ornamental plaster, Henry Watterson, a local carpenter, oversaw both the industrial and ornamental woodwork.

Construction issues By April 1901, the cost of the new Citizens Building had come down to just $450,000 ($ in dollars).; Variety Iron Works of Cleveland was hired to erect the steel frame of the building, and razing of the existing structure was scheduled to begin April 1, 1901.

In the late fall of 1901, a major dispute occurred between Citizens Savings and architect Levi Scofield, who was erecting the Schofield Building on the property adjacent to the east side of the new bank high-rise. Citizens and Scofield reached an agreement in which their two buildings would share a wall. Unlike the Citizens Building, which had a portico and small plaza in front of it, the Schofield Building extended all the way north to the property line, an additional . The bank did not want Scofield to build a plain brick wall next to their elaborately decorated new building, so the two sides signed an agreement in which Scofield agreed to build a wall at least thick. To accommodate the thick wall, the bank allowed Scofield to encroach onto their property by . Scofield also agreed to adorn his wall with pilasters (ornamental columns). The agreement required that the base of the pilasters extend outward from the wall by at least .

Scofield built the wall and pilasters, but the bank discovered that they extended onto the bank's land by more than the allowed . The bank sued. Scofield tore down his wall, and rebuilt it. This time, he embedded the pilasters into the wall like bas-relief. Once more the bank sued, arguing the base of the pilasters did not extend the required from the wall, and again Scofield tore down the wall. The bank offered to allow Scofield to build a thinner wall, but Scofield said this would be a structural danger to his building. The written agreement the two sides had signed was in conflict in several places, and the parties turned to the local Court of Common Pleas to resolve their dispute.

Despite several attempts to reach an out-of-court settlement and a visual inspection of the partially-completed Citizens Building,; ; the court was unable to find any law or precedent with which to guide its decision. On January 10, 1902, Scofield's engineering staff pointed out that an iron column at the northeast corner of the Citizens Building jutted into the space for Scofield's wall. The court suggested a compromise: Rather than have Scofield's brick workers chip bricks to fit around the column (at significant cost and time), Citizens Savings would allow the Schofield Building to encroach slightly into the space allotted for the shared wall, but no more than needed to accommodate a single brick's width. This would allow Scofield to accommodate the jutting column into his wall. In return, Scofield would move his non-shared wall back , and enlarge his pilasters so they more closely mimicked those on the front of the Citizens Building. The two sides swiftly agreed to the compromise to avoid a ruling by the court which neither party would be happy with.

Construction completion The time-consuming dispute with Scofield disrupted the construction scheduled for the Citizens Building. With Citizen Savings forced to vacate its existing building (which was due to be razed), the bank was forced to occupy temporary quarters beginning February 3, 1902.

Although the Citizens Building was not fully completed, the structure opened to the public on September 28, 1903. On opening day, the bank was open from 7 AM to 7:30 PM to accommodate the several hundred people who thronged the building to see its luxurious interior. The safe deposit boxes and vaults were completed at the end of October 1903. More than $1 million in bonds, fur clothing, rugs, household silver, stocks, and other items were moved to the new bank.

About the building As completed, the Citizens Building consisted of 14 floors, 13 above-ground and one below-ground. The base of the edifice was rectangular, but from the third floor upward the structure was a U-shape (facing north). The shape meant that no interior office was more than from natural light. The building's frame was made of steel, with reinforced concrete floors. A new design, in which steel T-beams were embedded cross-down in the concrete, was used for the floors. This saved weight and expense, and yet was stronger than using I-beams.

The Citizens Building was Renaissance Revival in style, with the exception of its Neoclassical portico. This mixed design was somewhat controversial among architects. The facade of the first two floors was granite. The third through eleventh floors were clad in brick, with ivory colored, glazed terra cotta around the windows. The two uppermost floors were completely clad in ivory-glazed terra cotta.

The portico The design of the entrance portico purposefully mimicked the Parthenon on the Acropolis of Athens in Greece. The portico was set back from the Euclid Avenue (north) property line by .

The portico consisted of four columns with Doric capitals. Each of the columns was high and in diameter, and made from a single piece of granite. The tympanum supported by the columns was designed and sculpted by Joseph Carabelli, a prominent granite sculptor in Cleveland. Like the columns, the tympanum was carved from a single piece of granite. Sources differ as to the subject matter portrayed. One description said the work depicted an allegorical figure of Industry, with other figures laying tributes at her feet. Another description, however, said that the work showed an allegorical figure representing Banking, who received gold from figures representing the city's sources of wealth and distributed this gold to the poor and elderly. A third source described the work as consisting of 12 figures representing Industry and Thrift.

The portico masked the entrance to the main bank of the Citizens Savings and Trust. This was a double-door entrance somewhat larger in height and width than a normal door. The architrave (the area that outlined the door frame) was inlaid with glass in a motif designed and executed by Tiffany & Co. The massive bronze doors themselves did not open inward or outward, but rather slid sideways into the walls.

Left (east) of the portico was a door leading to a foyer which provided elevator and stairway access to the offices on the third through thirteenth floors. Right (west) of the portico was a set of double-windows that let natural light into the women's banking parlor.

Lobby and lobby side rooms

The main bank entrance led to a lobby wide and deep. The lobby had a barrel vault ceiling of leaded came glasswork, which provided extensive natural light. The lobby walls and pilasters were clad in Italian marble. The pilasters, architraves, door lintels, and pier above the door featured inlays and designs of colored glass, gold, and mother-of-pearl by Tiffany & Co.

On the left (east) side of the lobby, a door led to the foyer entrance for the upper floors. This area featured the same white Italian marble walls and pilasters with Tiffany inlays.

On the right (west) side of the lobby, a door led to the women's banking parlor. The walls of this room were covered with silk brocade tapestries. The walls and pilasters were inlaid with Tiffany-designed decorations in ivory and gold. The furniture, commissioned specifically for this room, was of mahogany and upholstered in green damask.

A second door in the west side of the lobby led to an elevator and staircase that provided access to the second floor above, but the bank's offices and special departments were located.

Blashfield and Cox murals The lobby features two allegorical lunette murals, one by Edwin H. Blashfield on the left (east) and one by Kenyon Cox on the right (west). The two artists knew one another well, having worked on projects for the World's Columbian Exposition in Chicago in 1893 and for the Library of Congress in Washington, D.C., in 1896 and 1897. The two men worked in separate studios, but regularly compared notes while working on their commissions for the Citizens Building.
