"Because it took so long because it was such a big project, their life circumstances changed. They wanted to keep it new so it was more appealing to potential buyers."
Designed by Hulena Architects, the property features a double-storey foyer, large fireplaces, formal and informal living and dining areas and a top floor "dedicated to the master of the house".
"With a separate lounge adjacent to the imperial office fit for a president, the east wing portrays a Hollywood dressing room, an enormous bedroom suite, including en suite bathroom finished in natural stone."
The home also includes a gym, sauna, video surveillance and a guest wing above the six-car garage with its own kitchen facilities.
It is fully furnished with Baker and Henredon furniture.
"Anyone who understands quality will see the finish on it, it's a pretty amazing finish," said Mr Boulgaris.
"The majority of the flooring is solid oak and Marie Antoinette herringbone. It took several months just to lay the floor. It's got secret, hidden corridors in the house ...
"Someone with the money would appreciate having that sort ofquality."
Mr Boulgaris said the property looked over the surrounding countryside - and the view included a glimpse of the Dotcom property in nearby Mahoenui Rd.
