Kevin McCloud returns to a unique Japanese-Welsh fusion home in the Wye Valley to see how the improvised building weathered one of the wettest winters on record. Tamayo Hussey has missed Japan ever since she moved to the UK 15 years ago with her husband Nigel. To stave off the homesickness they decided to transform their home into a one-of-a-kind Japanese house – complete with Japanese roof bath, tatami room and paper sliding walls. Kevin finds out if it has brought the calm and tranquillity Tamayo remembers from her childhood in Japan.
