George returns for a Christmas special, visiting Christmas-themed builds including a gingerbread house, an underground grotto decorated with over four and a half million shells, and a beach hut advent calendar where every day a festive space opens its doors to the public. George also catches up with expert designer William, to look back on the extraordinary journey to transform his 1970s caravan into a spectacular 21st century holiday retreat.
