Filthy ‘Riche’ Fifth

Fifth Avenue real estate is getting even pricier.

The Swiss luxury group Richemont has just plunked down $375 million to buy a mere 24,800 square feet at the base of the St. Regis Hotel, according to a report.

In July, The Post reported the sellers were considering offers of that amount from groups that included a luxury retail company.

The deal, first reported by Real Estate Alert, closed recently.

The gold-plated purchase by Richemont, whose wholly owned luxe units include Cartier, Alfred Dunhill and Montblanc pens, boils down to a sky-high $15,120 per square foot, nearly twice the $8,300 per square foot Inditex paid last year for its 39,000-square-foot Zara store at 666 Fifth.

Richemont did not respond to requests for comment.
