Stadium House (Welsh: Ty Stadiwm) is the second tallest building in Cardiff, Wales, which stands next to the Millennium Stadium. The 255ft (78m) tall building is owned by BT Group, and recently underwent a £7.1 million refurbishment programme.
Work started on the building in March 1974 and was completed in 1976. The building is now clad in white and blue, while the roof is topped with a 131ft (40m) stainless steel spire, which is lit up green and white in the evening, to compliment the cladding. The addition of this spire qualifies the building as the tallest in Cardiff.
