21 Birnie Court was an 89 metre tall tower block in Glasgow. It was part of the Red Road area. It was completed in 1966 and had 31 floors. As with the other blocks on the Red Road estate, it was constructed using the steel frame structural system with a mixture of masonry and asbestos panelling.
It became the second of the Red Road towers to be demolished (and the first of the estate's six 'point blocks), when it was felled by a controlled explosion on Sunday, 5th May, 2013.
