Monmouthshire: The Japanese House

Kevin McCloud meets Tamayo Hussey, who has missed Japan ever since she moved to the UK 14 years ago with her husband, quantum physics professor Nigel. The couple want to transform a 1960s forester's lodge into a unique Japanese house, complete with a tatami room - decorated in her homeland's traditional style - sliding paper walls and a bath on the roof. Keen to keep costs down, they have decided to engage only the design skills - rather than the full services - of an architect, so with no previous building experience they tackle the project alone.
