Aulnay-sous-Bois Property Prices Surge as Grand Paris Express Arrives

Property listings in Aulnay-sous-Bois recorded 142 sales in June 2026, the highest monthly total since records began in 2019 for this Seine-Saint-Denis suburb.

The surge follows the partial opening of Grand Paris Express line 16 stations serving the area, which now connect Aulnay directly to central Paris in under 25 minutes. This infrastructure push comes as Paris proper maintains an average of 10,000 EUR per square metre while outer arrondissements from 1 to 8 remain premium and 9 to 11 show steady but slower gains.

Buyers are focusing on streets around the new Aulnay station and the adjacent Parc du Sausset, where three-bedroom apartments listed at 5,950 EUR per square metre moved within three weeks. Local estate agents also report interest near the O'Parinor shopping centre, which anchors daily amenities for new residents commuting via the extended metro network.

Metro Connections Drive Price Growth

Official data from the Paris Notaires showed average transaction prices in Aulnay-sous-Bois reached 6,150 EUR per square metre in the second quarter of 2026, up 11 per cent from the same period last year. That figure still sits well below the 8,400 EUR average recorded in nearby inner suburbs such as Pantin, leaving room for further adjustment as line 16 services expand in 2027.

The Grand Paris Express project, funded through the Société du Grand Paris, has already delivered pedestrian upgrades at the Aulnay station forecourt and new bus interchanges linking to the Parc des Expositions at Villepinte. These works coincide with the arrival of corporate tenants at the nearby Aerolians business park, which added 1,200 jobs in logistics and light manufacturing over the past 18 months.

Practical Steps for Buyers

Prospective purchasers should review listings within 400 metres of the new line 16 entrances first, as those addresses command the strongest rental yields at present. Checking the latest notarial price sheets for June and July remains essential before making offers, particularly for units in buildings completed after 2020 that qualify for energy-efficiency grants tied to the metro corridor redevelopment.
