Tiger’s Chairman Michael O’Flynn is now seeking funding for the 510,000 sq ft office scheme known as The Haymarket in the hope that construction can begin in 2012.
The office-led scheme also includes around 58,000 sq ft of retail and leisure and a 245-bedroom Travelodge hotel.
O’Flynn said: “Achieving consent for a scheme of this nature in Edinburgh is a real achievement and good news for all concerned.
“We have a number of parties who are keen to co-fund this development.”
