Telereal Trillium (now styled TT Group) is a commercial property investment, development and management company, headquartered in central London, England.
The majority ownership of TT Group is privately held by three funds settled under the Bernard Pears 1967 Family Trust.
Trillium was formed in 1997 to acquire the 1,500,000 square metres (16,000,000 sq ft) property portfolio of the Department for Work and Pensions, which it did in 1998.
After Pears bought the remaining 50% interest in Telereal in 2005, the company completed the purchase of the property portfolio of the DVLA under a 20-year deal.
In 2008, Trillium signed deals to manage the property portfolios of the Royal Mail and Birmingham City Council.
