Landmark Trust in Britain allows you just that pleasure. One of many properties they offer was recently the center of much debate and an ingenius renovation: Astley Castle.
House and Garden magazine, the castle was a ruined shell since 1978 when the hotel it housed burned to the ground. However it held a storied past dating to the 12th century despite its rather forlorn existence throughout the 20th century.
Witherford Watson Mann were chosen who preserved the damaged shell and ingeniusly inserted a modern house - utilizing the ruins to their best advantage.
