Origin and history
The Poirier Building, located at 7 avenue Jean Janvier and 1 rue Jean-Marie-Duhamel in Rennes, is a six-storey report building built in 1928. Its architecture combines post-haussmannian style and Art Deco, with a facade decorated with mosaics particularly visible on the first and fifth floors. A rotunda surmounted by a dome marks its visual identity. These mosaics, made by Isidore Odorico, were renovated in 2017 by the Patrizio family, also from Italy.
The building is the work of architect Jean Poirier, active in Rennes between 1928 and 1936, where he designed several residential buildings. Its central location and the quality of its ornamentation make it a remarkable testimony to the Breton architecture of the inter-war period. Since December 10, 2014, it has been listed as a historical monument and has been awarded the "Twentieth Century Heritage" label, highlighting its heritage value.
Historical sources, including the works of Jean-Yves Veillard and Hélène Guéné, highlight the role of Isidore Odorico, a Mosaïst Art Deco whose work in Rennes is documented. The building also illustrates the urban evolution of the city, combining Haussmannian heritage and 1930s innovations. Its official protection in 2014 and the renovation of the mosaics in 2017 demonstrate a continuing commitment to its preservation.
