Chibnall designed a four-bedroom, four-bathroom home. Guest accommodation, with a separate kitchen and its own entrance, is joined to the rest of the house by an elevator to all three levels.
Views from the master bedroom balcony sweep from the city to the west, across to the North Shore and on to Rangitoto, Motutapu and Browns islands.
The sprawling home also boasts a walk-in, temperature-controlled wine room.
The home was for sale in 2008 but was taken off the market when it failed to sell at auction.
The recent Auckland Council revaluation saw the property's value jump to $4.15m from $2.2m in 2008.
A real estate agent said a private sale in the high-end market of the Henrys' home would save ten of thousands.
"With high-price properties the agent would usually negotiate a fee, but it would normally be 1 or 1.5 per cent on the total rather than the standard 4 per cent."
