The Balfron Tower is the architectural twin of Trellick Tower with it having come first. In doing so Goldfinger made an important architectural breakthrough of separating a building into a service tower, and an accommodation tower.
Like Trellick Tower the services are located separately from the main block and linked by walkways designed spatially around train carriages to create familiar dimensions.
The Balfron Tower was featured heavily in the film 28 Days Later where two survivors had successfully fortified it and holed up. It was only deserted when it failed to rain and they ran out of water.
