When architect Tony Godwin wandered into a seminar on the passive house standard at Ecobuild ten years ago, it was the start of a journey that would eventually see him design and build his own passive home on a sloping site — and learn some hard lessons along the way to achieving a comfortable, ultra-low energy family home with tiny energy bills.
