The Red House, Bexleyheath
This was where it all started, or at least instrumental in the story of the Arts and Crafts movement. The home of William Morris and co designed by Philip Webb, it was a beautiful retreat for Morris and his wife Jane from his work in London.
But I can't help thinking pretty impractical too - very cold and not suitable for his poor health. Nowadays it sits right in the middle of a very sub urban housing street.
