Construction of the building began in 1928 and was intended from the outset to be an imposing administrative office, being at that time the tallest building in the city. The architecture style is eclectic in nature , embracing the two styles , one neo-roman and another one even better represented at the time, the neo-Romanian . Neoromanian style include massive and deep bosses, continue with Hochparter that provides the main access and having a Piano Nobile decorated with loggia , developed on two levels continued in the richly decorated interior space for boardroom and festivities. Upper register , below the cornice , is treated with frequent frames , they come from the same semantic Brancoveanian style. The main body of the building benefits from the presence of a richly decorated marble staircase that connects the basement and 3rd floor . Celebration Hall is decorated with murals by Olga Greceanu . Two other paintings by the same author were found in Maier Office.Another important component of thebuilding – the clock tower is receiving attention paid to the upper area and materialized by a terrace with decorations and the statue of a knight with shield and armor ( conducted by Alexander Dumitriu in 1929 ) which, over the years, has managed to become a visual landmark of Bucharest. Body side of the building , built in a later stage , althoughcontinuingexterior facade elementsfrom main body, the interior shows no lavish architecture with a purely functionalist austere air , with lack of any fine architectural elements and arrangement of access vertical in the last bay as a large service stair .
In 2008 the building has entered a process of consolidation, which resulted in partial modification of interior architecture , but without affecting the flagship areas of the building . In addition, in 2009 a fire destroyed 90% of roof framing building. So in 2010 it was started an interdisciplinary project left from the historical study of the monument, cultural resource identification and justification of the intervention . This project led to the creation of new frameworks, that follows the initial shape of the roof , but also created new space with a well-defined architectural identity . Later works project were divided into two categories: artistic components – targeting restoration and reconstruction of interior and exterior decorative elements of architecture ,and construction and facilities – which aims to develop and functionalize rest of the building and outdoor spaces to accommodate current requirements.
