Boeing 747-8 private jumbo jet photos: Inside the ultimate VIP private plane

Could flying first-class get any more luxurious? It definitely has for one super wealthy VIP.

The unnamed VIP is the owner of a Boeing 747-8 private jumbo jet, purchased at a reported cost of £400 million (approximately A$792 million).

The 747-8 aircraft, which can typically carry up to 450 passengers as a commercial airliner, was purchased from Boeing with an unfurnished interior. It was then customised with interiors and features that could render any other private jet inadequate.

The personalised 787-8 features a large open seating area with lounge, window blinds and TV; a master bedroom suite and custom-designed storage units, lounge and windows; a large dining room; and an office space that can also be used as a conference room.

US-based Greenpoint Technologies, a company that specialises in interior fit-outs for private individuals and heads-of-state, completed the interior designs.

The project is reported to have taken three years to complete. The cost breakdown is estimated at £160 million ($A316.78 million) for the customised fit-outs on top of the retail costs of £230 million, The Daily Mail reported. The fit-out was completed in December 2014.

The 747-8 is the world's second-largest commercial aircraft after the Airbus A380 superjumbo (though the 747-8 is longer). The VIP 747-8 version is said to offer 4786 square feet (444.63 square metres) of cabin space with the 747-8 Aeroloft version offering an additional 393 square feet (36.51 square metres), according to a report by the Seattle Post-Intelligencer.

The 747-8 Aeroloft version also has private sleeping berths located above the main deck in the aft section and is fitted-out with custom designed furnishings and a forward entry staircase.

Greenpoint Technologies has not released official photos of the interiors but digital renderings have been made available (see the photo gallery above).

Boeing has delivered eight out of the nine VIP 747-8s that have been ordered worldwide.

The aircraft maker usually delivers its jets destined for private use with a bare interior to a finishing company, like Greenpoint, who then customises the interiors according to client needs.
