Kevin McCloud knows a thing or two about building houses - you've probably seen him on the telly as the host of the British show Grand Designs.
It's the show that follows people on a mission to build their ultimate dream home, or have extraordinary plans like converting old water tanks into a house.
Next month McCloud will make his way down here where he's keen to help New Zealand embark on one of our most important building projects of all time: The re-design of Christchurch.
Europe correspondent Melissa Davies met with him in London.
