But theses renderings show just what £400million will buy you if you're splashing out on a full-size Boeing 747-8 for one person.

The aircraft, which would normally carry up to 450 passengers, has been converted into a private jet for an unknown owner with a complete re-design to feature everything you would normally find on board a luxury mega yacht.

The plane retails in at around £230million, and the estimated 'improvement' work is an additional £160 million taking the overall expense to almost £400million.

And Greenpoint Technologies, who have transformed the plane, have delivered the aircraft to an unidentified private owner after three years of hard graft.

Although no photos have been released, the company have shown off digital renderings of the design, and these give an accurate portrayal of the class and luxury inside.

The 747-8 can normally cater for around 450 passengers, and is the world's longest passenger jet with a cabin space 20ft wide and 200m in length.

That is more than enough room to add in the owner's specifications for the redesign, that included a restaurant, dining room, master and guest bedrooms, two large lounge areas and office space.
