The  apartment atop a planned luxury tower in Monaco could be listed for $280  million, making it the world’s most expensive penthouse if it sells for anywhere  near that price.

Current renderings for the residence, at Monaco’s Odeon Tower, show a five-floor home with 35,500 square feet of space.

They also show a private infinity pool with a water slide

The price tag on the penthouse is pure speculation, based on the size of the space and current prices for apartments in  the building, which start at £5,200 per square foot ($7,958 at  current exchange rates), a representative for the developer told  us.

If the multi-level residence does sell for the anticipated $280 million, that would make it the most  expensive penthouse in the world, followed by a residence at One Hyde Park in London that sold for $216 million
