Colin and Emma Bannon live in a beautiful, white Regency villa straight out of Mary Poppins. But the interior is straight out of a 1970s disco, complete with mirror ball, remote control wood burner in the drawing room and coloured-glass tiles where a disco Jacuzzi once sat. As they pull up floorboards and expose the original walls, the house starts to surprise the Bannon's with little glimpses of the past. Not only do they reveal the home’s true history, but Colin finds out something about the architect who built it that links back to his own past in Canada.
