Construction of the new bus station can now go ahead after the Council approved a new scheme and funding approach last month.
The approval will see a modern transport interchange in Central Square that can meet the needs of the Welsh capital city.
The Council has been trying to deliver a Grade A office-based scheme as part of the plan but until now has not been able to realise that ambition without securing a tenant in advance of construction.
Over the past few months, the Council has been working with Welsh Government to secure the office component of the development.
As a result, a joint-venture approach involving the Council, Welsh Government and the Council's development partner, Rightacres, will allow offices to remain as part of the scheme.
Without this joint venture, it would have been necessary to rely on a mixed-use scheme comprising of an element of student accommodation and possibly a hotel. This is no longer the case.
A new planning application will be required to approve the changes, but it is anticipated that the existing planning consent for the bus station element will enable an early start on site in the New Year.
