Property investment firms Hines and Peterson have submitted a planning application to redevelop the former Central Bank HQ on Dame St in Dublin to turn it into a "landmark destination".
The development would see the creation of a glass-roof, two-storey 20,000 sq ft rooftop hospitality destination and viewing area that would offer a 360-degree view of the city.
The mixed-use scheme, known as 'Central Plaza', would also include retail, restaurants and café uses at both street and basement level.
It is understood the cost of the redevelopment would be at least €70m.
The proposal also envisages an expansion of the existing plaza and the creation of a new streetscape towards College Green and along Fownes St and Cope St.
The new 'Central Plaza' is expected to be able to accommodate 1,000 office workers and create more than 300 full and part-time retail and hospitality jobs, upon completion.
The US and Hong Kong-based firms bought the building earlier this year for around €60m, with the Central Bank moving to new offices on North Wall Quay in the city.
