Kevin McCloud revisits a unique Japanese-Welsh fusion home in the Wye Valley, completely transformed from a damp old forester's house in 2013. 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 turn the property into a one-of-a-kind home, complete with roof bath, tatami room and sliding paper walls. Kevin finds out how this somewhat improvised building weathered one of the wettest winters on record and if it has brought the calm and tranquillity Tamayo remembers from her childhood in the Far East.
