Birmingham's The Cube put on sale
The Cube development in Birmingham city centre is to be sold.
The 23-storey building, which was completed in 2010 at a cost of £100m, was designed by Ken Shuttleworth who is renowned for the "Gherkin" in London.
The project has been in administration for two years after developers were unable to reach agreement with banks over funding for it.
Owners, the Birmingham Development Company (BDC) said it was "a good time in the property market" to sell.
The building contains 244 apartments, several suites of offices, shops, a four-star hotel and a Marco Pierre-White restaurant, which boasts views across the city centre.
BDC has not revealed how much it is asking for The Cube but said it had had "a lot of interest".
The director of the company, Neil Edginton, said: "We're holding a closed auction and we've got a long list of people that we're short-listing down.
"People are submitting bids but there will be a bit of negotiation along the way."
