From the Wikipedia page

The William Morris Gallery, opened by Prime Minister Clement Attlee in 1950, is the only public museum devoted to English Arts and Crafts, designer William Morris. The Gallery is located at Walthamstow in Morris's family home from 1848 to 1856, the former Water House, a substantial Grade II* listed[1] Georgian dwelling of about 1750 which is set in its own extensive grounds (now Lloyd Park). The Gallery is currently undergoing major redevelopment and will reopen in July 2012.
