A High Court challenge has resulted in a revised construction programme, with the shortest build time meaning Spurs must leave White Hart Lane to allow the new stadium to be built.
However, this will not be in time for the start of the 2017-18 season.
Spurs believe moving to the three-hectare site will help them increase their revenues and compete better against Europe's top clubs.
In 2011, Tottenham lost out to West Ham in a bid to move to the Olympic Stadium in Stratford.
Whether sharing the Olympic Stadium with the Hammers, who move to the site in 2016, is an option remains to be seen.
