estate was bought by Peter Urban Sartoris, a Genevois banker who had lived in London for many years. On his death in 1833 it was inherited by his 6 children, who urbanised it and named the rue Sartoris. They sold the last of their interests in 1865. The commune of La Garenne-Colombes was created on 2 May 1910 by detaching its territory from the commune of Colombes. Demography As the commune's territory is entirely built up, population can only grow if buildings are demolished and replaced by bigger buildings for more people (higher, less gardens). Thereby the population will grow certainly over the 30,000 after many reconstructions in the "Champs-Philippe" neighbourhood, with a density over 17,000 inhabitants per square kilometres (43,855 inhabitants per square miles). According to statistics, La Garenne-Colombes is an average city of the Hauts-de-Seine department (Paris region), which is one of the richest places in Europe. Economy The landscape looks like an American CBD (Central Business District). But this is in the suburbs of Paris, which do not look like the downtown Paris districts surrounding the Eiffel Tower or the Champs-Elysées. Paradoxically, the most advanced part of the city of Paris, geographically speaking, is on the outskirts of the city itself. There used to be many workshops in La Garenne-Colombes, as in a large part of the Hauts-de-Seine department. Today, it is mainly a residential city. However, some 1200 business units are there. Tertiary activity The service industry is paramount in the economy of La Garenne-Colombes. The proximity of La Défense increases this phenomenon. There is : Peugeot study offices Boston Scientific International RATP's Charlebourg center The arrival of the Tramway in 2012 resulted in a redevelopment of a part of the city, and should bring a new breath of life to the local economy. Urbanism The city In spite of the proximity of La Défense and Paris which has applied a strong pressure, no big buildings were built in La Garenne. Residential buildings (detached homes and apartment buildings) account for the majority of the building stock in La Garenne-Colombes. Many of these buildings were constructed in the early 1900s. In a large part of the town, new construction is limited to 4 floors. The neighbourhood of the place de Belgique and National boulevard, which is the entry of La Défense, is being redeveloped.
