The new broadcast centre and HQ for BBC Cymru Wales lies at the heart of the Capital Square redevelopment in the centre of Cardiff and is an exemplar, BREEAM outstanding building, setting new standards for innovative, flexible and cost-effective workplaces.

Designed by Foster+Partners, the new headquarters brings together a wide variety of studio, administration and support spaces in a single building, which is open to the city, highly flexible, energy efficient and provides a creative, collaborative and inspiring workplace for BBC staff.

Located opposite Cardiff Central Station, the project is situated on the site of the former bus station to create a dynamic media quarter around Capital Square, which is planned as a major new public space for the city.

“The building is designed to be open and welcoming – visitors can access the ground floor and look up through a full height atrium into the working spaces above, as well as into a new café facing the square,” explained a spokesperson for the architectural team, which was led by Toby Blunt and Adam Newburn.

“The design also establishes a sense of openness and transparency between different departments to create new opportunities for collaboration and interaction. The heart of the headquarters is a 4,000-square-metre ‘hub’, which extends across three linked levels and incorporates studios, offices and production facilities. The scheme includes a sheltered garden on the roof of the hub, which is connected to a restaurant and provides a unique venue for filming, as well as a valuable social amenity for staff.

"The project targets BREEAM ‘outstanding’ environmental accreditation with strategies such as chilled beams, locally sourced and recycled materials and an efficient envelope. Mechanical systems have been carefully integrated to create a highly flexible interior, which can anticipate and respond to changing technologies.”

Foster+Partners was appointed to the project in 2010 by the Rightacres Property Company and the 30-metre high, 25,600m² building was completed in 2019. Last year it won both the Innovation in Design category in the RICS Awards and was winner of the Building Project of the Year title in the Constructing Excellence Awards, Wales.


Two types of curtain walling, and entrance doors, by Kawneer, including the first use in the UK of a new severe duty welded door, feature on the award-winning building.

Kawneer’s AA®100 capped and zone drained aluminium curtain wall, complemented by its SSG (Structurally Silicone Glazed) and mullion-drained sister product, have been used throughout the glittering façade of the striking new headquarters building for BBC Cymru at Three Central Square.

They in turn are complemented by thermally-superior AA®720 doors and the new dual colour AA®190 TB severe duty welded doors with class-leading thermal performance that is so robust they are offered with a lifetime guarantee.

The high-performance ceiling system for BBC Wales’ new facility was designed by Senior Architectural Systems in partnership with Sheppard Robson.

Over 5000m2 of SAS International’s acoustic metal hybrid raft ceiling systems provide a distinctive aesthetic suited to a 21st century digital broadcast environment.

Hybrid metal acoustic rafts, made up of varying sized panels supported on a concealed grid with bespoke upstands, are suspended between the rows of chilled beams that supply cooling to the office floors. Light fittings in a distinctive cruciform arrangement are suspended beneath the ceiling.

The TV studios, with exceptional acoustic requirements, are lined with SAS International’s WP10 metal acoustic wall panel system.
