[7] A replacement was expected to be completed by 2017, designed by Foster and Partners, on the site of the nearby Marland House and Wood Street NCP multi-storey carpark.

[8] Foster and Partners were dropped from the project in 2018, after the Welsh Government took over responsibility from Cardiff Council, though by this point the architecture firm had completely redesigned the proposals.

[10] In July 2019 it was announced that contracts had finally been signed between the Welsh Government, finance company Legal & General, and the developers Rightacres, to begin work constructing the scheme.

[11] Having previously built the adjacent BBC Cymru Wales New Broadcasting House and 2 Central Square, in December 2019 construction company ISG secured the £89 million contract to build the new Cardiff Bus Interchange.

As well as the covered 14-bay bus station, the Interchange includes 318 build to rent apartments, about 90,000 square feet (8,400 m2) of office accommodation, and a retail unit.
