Le Plateau occupies the upper part of Athis-Mons, at 92 metres above sea level, on either side of the avenue François-Mitterrand which crosses the town from west to east. It is the area that carried the interwar expansion of suburban housing, when Parisians came to settle on the farmland of the plateau.
The district is laid out around that axis, with the rue de Bellevue, the avenue Marcel-Sembat, the rue Maurice-Guillon and the rue de la Gaîté, and extends west towards the avenue Jacques-Chirac, the rue de la Bastille and the rue des Cernats, where the most recent housing schemes in the town are found.
On the market, Le Plateau shows the highest average price in Athis-Mons, at around 3 654 €/m² for an apartment, on about 45 sales a year, the largest volume in the town. The median, at 3 617 €/m², tracks the average: the market there is homogeneous. The district gains 3,2 % over twelve months.
Le Plateau attracts families looking for a house with a garden three quarters of an hour from Paris, and buyers of new-build flats on the recent schemes in the west of the district. It is the most sought-after area in the town, both for the quality of its housing stock and for its distance from the main roads. Exposure to aircraft noise from Orly varies noticeably from one street to the next and weighs in negotiations.
