Chennevières is a large housing estate built in the mid-1970s, on a grid of streets and blocks named after the French provinces: la Bourgogne, la Flandre, la Savoie, l'Aquitaine, le Poitou, and the Dauphiné, Picardie and Aquitaine blocks. It has been the subject of a full refurbishment carried out under the Agence nationale pour la rénovation urbaine, the French national urban regeneration agency, with a multi-sports pitch, an urban park, a local shopping centre and the residentialisation of the housing.
The district has a community centre approved as a social centre by the CAF, the French family allowances fund, at 2 place Louise-Michel, itself renovated from 1 July 2023. The refurbishment programme continued on the housing blocks: two hundred homes on the Dauphiné block, then one hundred and twenty-three on Picardie and one hundred and thirty-six on Aquitaine.
This page also covers LE PARC LE NÔTRE, adjoining to the south-west, and the grouping is not an invention: it is exactly the perimeter of the official priority urban policy area, which is named "Chennevières - Parc Le Nôtre". This sub-area holds two major elements of the town's heritage, the church of Saint-Ouen, listed as a historic monument, and the park laid out by Le Nôtre. Five streets were checked by point-in-polygon across the whole: the avenue de Chennevières, the place Louise-Michel, the rue de Flandre, the boulevard Ducher and the avenue de Verdun.
The district sits at 3 315 €/m², 10 % above the town-wide average, which makes it the second highest price in the town. It records however only five apartment sales a year in total, the smallest volume in Saint-Ouen-l'Aumône, and its annual series is missing two years out of five: these figures should be read with a far wider margin than the others. It gains 5 % over five years and 9 % over twelve months. It is the only priority urban policy area currently in force in the town.
