Hammerson is pleased to announce that it has secured Primark for a large new store at Les 3 Fontaines as part of a series of landmark openings. Primark will take the majority of the 110,000 sq ft redevelopment at Cergy while advanced negotiations are taking place with a further flagship brand for the remaining retail space. Works on the redevelopment are due to start from September for an opening in 2027, with its completion acting as the final phase of repositioning at Les 3 Fontaines. These new signings join a line-up of recently agreed brands including Jack and Jones, Adopt and Popeyes.

Primark was the brand most requested by customers and will add to the 200 occupiers already at Les 3 Fontaines across retail, leisure and food and beverage. Major retailers already include Sephora, Fnac, Adidas, Mango, Footlocker, Lego and Zara, while recent openings comprise Action, New Yorker, Snipes and Celio.

Located in Cergy, Val d'Oise, Les 3 Fontaines is the region's leading urban shopping destination. The expansion will drive significant footfall and increase the already strong catchment, with annual footfall of over 12m (up 6% in 2024) and a population reach of more than 10m. Sales were up 3% in 2024 and strong momentum continues in 2025.

These new deals will add c€2.5m of new income while the total cost of the redevelopment will be €30m. This includes the acquisition of a car park and adjacent land from the local authority, for which Hammerson is in advanced discussions, to consolidate the estate.

Hammerson actively invests in repositioning projects across the portfolio and benefits from an additional 70 acres of strategic land. Projects are located in or close to existing assets and help to densify our destinations whilst offering attractive risk-adjusted returns with additional income streams.

Aymeric Metais, Director of France at Hammerson plc, commented: “This is a major new milestone for Les 3 Fontaines adds another 10% of lettable space, grows our income and offers a new and exciting offer for customers while boosting our footfall and customer reach. Through disciplined project management, everything is now lined up to start construction from September. This is another strong example of strict and targeted capital deployment, delivering strong returns while significantly enhancing our core portfolio.”
