It may sound surprising, but the largest listed building in England is indeed a London council estate. The Alexandra and Ainsworth Estate, to be precise, often referred to simply as Rowley Way. This brutalist behemoth sits in the London Borough of Camden and is a concrete warren interspersed with beautiful greenery and community spaces. It's a must for anyone with an interest in brutalist architecture. See it for yourself.
The Alexandra and Ainsworth Estate is located in the London Borough of Camden, close to South Hampstead railway station. For more information on the building and its history, visit the website here.
