Big-time developer Peter Cooper is completing a new mansion with a huge stone tower on a sprawling coastal property.
The Cooper Residence in the Bay of Islands is the third house to be built on the ambitious Mountain Landing luxury development.
Plans obtained from the Far North District Council show the main house is a two-level building with five bedrooms, a butler's pantry, terraces, decks and a dressing room.
The unusual stone tower has a cellar and barrel room.
The Cooper Residence is set on a headland in the isolated Purerua Peninsula, about a half-hour drive from Kerikeri.
