Nick Knowles follows the extraordinary rescue of Castle Howard in Yorkshire before its roof gives in to the Great British weather. Backdrop to classic period dramas like Brideshead Revisited, Castle Howard is one of Britain’s most loved stately homes. But since a huge fire in 1940, keeping the place alive has been the full-time occupation of the Howard family and today Nick Howard follows in his father’s footsteps to save the place from ruin, embarking on a huge project to rebuild its complex lead roofs, saving unique ceilings, and restoring a stunning stone portico before it’s too late.
