Developer Liam Carroll will require hundreds of millions in new finance from the banks in order to build developments on land controlled by the Zoe Group, which is seeking to go into examinership.

Carroll, who was taken to hospital last week, earned a last-minute reprieve on Friday night when his companies finally submitted letters of support from his lenders, with the exception of ACC, the Dutch-owned bank which has been seeking to have Zoe wound up. Most of the banks are backing the developer because they know Nama will pay more than double what the sites would achieve if they were put on the open market.

Dublin City Council has told the developer it has a "number of concerns in relation to the housing quality" of one of the proposed schemes on the 12 acres Carroll owns in the north docks, which are central to ACC's efforts to have Zoe wound up. The council also has issues with the "architectural design" of some of the scheme and its roads and traffic division "has serious concerns" about the level of car parking proposed.

On Friday, Carroll app­ealed to the Supreme Court to have Royceton, a key part of the Zoe Group, put into examinership along with six other companies. Royceton temporarily laid off a number of staff late last year, blaming "the severe downturn in business and the poor economic outlook". Some of them were then informed in late May that they were being made redundant.

"At this stage we do not see the business recovering to previous levels in the foreseeable future and are left with no choice but to make you're [sic] position with the company redundant," the letter to the staff said.

Zoe also submitted a new independent accountant's report from KPMG, which is understood to have been lined up as examiner if the petition succeeds, and new valuations of the Zoe Group's property portfolio. A new hearing on whether an examiner should be appointed to the group will be heard on Thursday.

In the initial hearing on Tuesday, Bank of Scotland Ireland was the only bank to definitively declare in court that it was willing to provide Carroll with additional finance to allow him complete developments.

Industry rumours that Carroll has not paid many of his staff for several weeks could not be confirmed last week.

Carroll told the High Court that in October of last year he had assets of €259.5m and bank debt of €149m. He is being personally pursued for €60m by Irish Nationwide and is also a named defendant in a €140m damages case being taken by Noel Smyth in relation to The Square in Tallaght.
