The site, which is located between Wood Street and Rose Lane, secured planning permission for a 35-storey mixed-use tower in 2023.
The new development will include 528 apartments, lounges, dining rooms, co-working areas, a cinema, gym and spa, alongside a separate two-storey pavilion building next to it, the Local Democracy Reporting Service said.
In planning documents to Cardiff Council, applicant REAP 3 Limited, a subsidiary of Bluecastle Capital, said the design had taken “tonal references” from nearby buildings.
“White Portland stone features on several of Cardiff’s significant civic buildings and many of the taller city centre buildings feature light tonal façade elements.
“Our façade and material proposals must sit comfortably within the city context and also provide a well mannered façade when viewed from a distance.”
Project 5Plus Architects said parts of the façade would also feature “subtle references to Welsh Celtic symbols” that drew inspiration from the country’s “rich visual heritage and identity”.
