Grand Designs New Zealand takes us into the heart of life's great unfolding human stories, where ordinary Kiwi families risk all to experiment.

In this series we follow 8 real estate agents who are selling a billion dollars' worth of property between them each year in New Zealand's most valuable real estate markets.

We visit a restored garden in its natural state, grow beans and talk trees.

Kirstie and Phil are in North London, home to some of the country's most expensive spots, and where property searching here is never for the faint-hearted.
