Hermitage has unveiled plans for the tallest mixed-use building in Western Europe.

The developer, a subsidiary of Russian company Stroïmontage Group, announced at Cannes that it was planning one 309-metre high tower and one 264 metre high tower at its Hermitage towers scheme at La Defense, Paris.

Mixed-use towers

The buildings, near to the river Seine, will total 2.7m sq ft of retail, office, hotel and residential space.

The bottom three floors of each tower will be given over to shops and the next 10 floors will be offices.

Floors 14-26 in each tower will be a luxury hotel followed by private residential accommodation. The top of Tower A will be made up of bars, reception rooms and a restaurant – Tower B will hold reception rooms and fitness suites.

Public facilities

The proposed scheme would also offer public facilities, located in a glass base including a 1,300 seat concert hall, a skating rink and a 16,164 sq ft contemporary art centre.
