Plans for a £100m investment that would secure an indoor arena and convention centre for Cardiff have been revealed.
It was confirmed last week that the Welsh Government and Cardiff council are in talks with the aim of engineering finance for a convention centre in the city.
However, it has now emerged that as well as a convention centre, with a capacity for up to 2,500 delegates, they are also looking to build an indoor arena with the capacity to accommodate 15,000 people. The site being looked at is Callaghan Square in the city centre.
The indoor arena would be able to stage major sporting events and concerts, as well as annual party political conferences.
It would be significantly larger than the current 5,000 capacity Motorpoint Arena, formerly known as the CIA.
The convention centre has an estimated construction cost of around £60m, with the indoor arena being around the same.
Other site options being considered include land at the Sports Village and land near the Wales Millennium Centre in Cardiff Bay.
But it is understood that a favoured location for both buildings is on five acres of land yet to be developed at Callaghan Square.
However, a planning application to develop a new 90,000 sq ft office scheme at Callaghan Square was lodged last week with Cardiff council.
Submitted by MEPC, the application is for a new 90,000 sq ft office development. While the tenant is not disclosed in the application, it is understood to be law firm Hugh James.
This means if plans for a convention centre and indoor areas are to be progressed at Callaghan Square, the Welsh Government and council would have to move quickly to agree a land acquisition deal with MEPC.
