Planning Status

Previous Outline planning permission granted for 500,000 sq. ft. of office with ancillary retail development


The successful first phase of the Callaghan Square development and city centre retail and office areas and to the West by Cardiff Central station, provides over 300,000 ft² of Grade A office space with occupiers including Eversheds, British Gas, British Transport Police, AECOM, JLL and HSBC. 

Located on the south side of the Square is the Welsh Government’s strategically important comprehensive regeneration site which comprises over 7.5 acres of prime land for redevelopment. Located adjacent to the main site is land under the ownership of Cardiff Council that also have the potential to be included in any future scheme of development. 

Whilst the redevelopment of site has historically been seen as predominately office-based location (previous outline consent for 500,000 sq. ft. of offices), the opportunity now exists for an exciting new mixed-use redevelopment adjacent to the proposed new METRO link from Cardiff Station to Cardiff Bay. The site is also bounded to the west by major commercial office development along Dumballs Road and the attractive new Cardiff and the Vale College campus. The development potential of this site could be in excess of 1.3 million sq. ft. of new development. 

Whilst this site is already well located in the heart of the city centre, the delivery of the expected METRO link from Cardiff Station to Cardiff Bay (subject to funding approval), would place it adjacent to a new METRO station with all the communication benefits that this offers to the site and for its future occupiers/residents. 

The site will be subject of a new masterplan that will guide the broad parameters for the future redevelopment site. The Masterplan is expected to report in spring 2024 which will help inform future development expectations.
