The Kenmore property group bought the Les Quennevais Precinct complex in a Royal Court transaction ten days ago.
It includes 36 shops, 34 flats, 35 garages and extensive parking.
The deal was brokered by commercial property advisers C B Richard Ellis.
Director Jon Carter said that they were working on the instructions of Deloitte Touche and PwC, administrators for Mr Leech.Mr Leech was declared bankrupt in October last year only two years after his companies had been valued at worth more than a billion pounds.
He was the first and only Islander in history to reach that mark.The Kenmore group was founded in 1986 by its current chairman, John Kennedy.
The initial focus of the company was the development of office schemes in Glasgow and Edinburgh.The value of the Kenmore portfolio is now in excess of £200 million.
Spokesman Lee Mayton confirmed that this was the company’s first venture in Jersey, although it does own property in Guernsey.The company literature says that it continues actively to seek acquisition opportunities in lot sizes from £2m upwards.
Kenmore are primarily looking for properties which require active asset management over a hold period of two to five years.Mr Mayton said that two bungalows that were also part of the deal were handed over with no tenants living there.
