€52M Metro Expansion Drives 9% Property Price Jump in Saint-Germain

The Paris transport authority confirmed last week that construction on the new southern entrance to the Saint-Germain-des-Prés metro station will begin in September, directly increasing values for apartments within 300 metres of the site on Rue de Rennes and Rue Bonaparte.

The timing coincides with the city’s updated mobility plan that prioritises faster links between the 6th arrondissement and the expanding business districts south of the river. Local agents report more inquiries from buyers who want shorter commutes once the new escalators and platform extensions open in late 2028.

Streets seeing the sharpest gains

Properties on Rue de l’Abbaye and around the Église Saint-Germain-des-Prés have recorded the largest price movements. Two three-bedroom apartments listed through the local branch of Century 21 in May both sold within ten days at €1.35 million and €1.42 million respectively, figures that sit 11 percent above comparable sales from the same period last year. The nearby Les Deux Magots café continues to draw footfall that estate agents say now extends further along Rue Bonaparte because of the promised shorter walk to the station.

Official Notaires de France data for the 6th arrondissement shows median apartment prices reached €14,850 per square metre in the second quarter of 2026, up from €13,600 twelve months earlier. The same dataset records a 22 percent rise in transactions for units under 60 square metres in the immediate catchment of the metro works.

Next steps for buyers and sellers

Anyone considering a purchase should check the latest plans lodged with the Mairie du 6e arrondissement before making an offer, as final alignment of the new entrance could affect a handful of ground-floor commercial leases. Sellers who list before the September ground-breaking are still achieving asking prices within 3 percent of valuation, according to recent agency reports. The project remains on schedule provided no archaeological finds delay the dig, a risk the transport authority has already budgeted for in its timeline.
