Reality TV stars Kourtney and Khloe Kardashian have reportedly been looking for space in Manhattan for a "full-concept Kardashian lifestyle experience".

The sisters, who are currently filming in the Hamptons, where they are opening a Dash store, reportedly looked at a 5,500 square foot five-storey corner property in Soho last week with plans for a huge "full-concept Kardashian lifestyle experience", reports contactmusic.com.

A source told the New York Post newspaper's Page Six column that the sisters want to turn the first two floors of the building into a flagship Dash store, with the other three storeys being used to house offices for the family businesses.

The whole building is available to rent for $2 million a year from real estate mogul Jack Terzi, who bought it for $15 million in May.
