Kerry Powell, LDNP Director of Communications and Resources said: "The Lake District National Park value and recognise the historic importance of the iconic white house and has long had an ambition to redevelop the property and reawaken this Arts and Crafts jewel.
"The recent designation of the National Park as a UNESCO World Heritage Site has encouraged us to look more closely at the opportunities the house offers and how we might restore it to its former glory.
