Unless you're Bruce Wayne, chances are you're not in the position to shell out £300 million ($486 million) on a home. However, that's exactly how much Britain's most expensive house is set to sell for.
Located by Hyde Park in London, it has 45 bedrooms and is seven storeys high and if it sells, it will be the largest privately owned property in the UK, more than double the previous UK house-price record of £140 million ($227 million).
The price tag on the 60,000sq/ft home includes a large swimming pool, industrial-size catering kitchen, underground parking and several lifts. As the place is located overlooking Hyde Park, there are security screens on the windows so no-one can see inside.
It's also thought to have millions of pounds worth of gold leaf adorning the walls and the windows are bullet proof.
Quick whip round, anyone?
