When it comes to the most expensive cities in the southern hemisphere, Auckland holds its own. So it's no surprise that an apartment billed to become New Zealand's priciest family home has just been listed on the city's property market. Overlooking Waitemata Harbour, the Pacifica Tower is due to open later this year. It will have 275 apartments, all of which come with views of downtown Auckland. But the very best views in the house are to be found some 178 metres above the city, on the tower's 53rd floor. That's where the Pacifica Super Penthouse, which crowns the skyscraper tower on Commerce Street, commands two floors of the building for its exclusive use. Designs for the space currently include five bedrooms and five bathrooms. Buyers can opt to design it themselves, or have interiors designed by the tower's developers. The huge space has scope for a mammoth open-plan kitchen, dining and living areas, as well as a butler's kitchen, a tasting room and an in-apartment spa. There's also a proposed indoor garden and conservatory that would offer residents amazing views of Auckland's famed Sky Tower. The listing is held by Jason Gaddes and Scarlett Wood of New Zealand's Sotheby's International Realty. The asking price for this towering skyscraper is only available upon request, but it looks set to hit the market at around $40 million New Zealand dollars (Dh89m). If the home sells at that rate, it will become the most expensive single-family home sold in New Zealand.
