Spurs have always been one of the biggest sides in the country, according to their ex manager.
And the Englishman, who was at the club from 2008 to 2012, stated that it will be a ground befitting a side who, in his eyes, are one of the major outfits in the country.
"Spurs have always been one of the bigger clubs and the new stadium looks fantastic," he said on Kicca.
Redknapp, who has also coached West Ham and Portsmouth among others, also praised the club's intention to link up with the NFL once the stadium is redeveloped.
"To have the NFL coming to play there as well will be a great experience, a good draw and they will fill the stadium," he added. "It’s a big initiative by the club to get involved with the NFL.
"It's only good for the club, good for the future.
"Tottenham have a great training ground now, it’s absolutely unbelievable so it’s all in place, everything is there."
The redeveloped White Hart Lane will be London's biggest club stadium, and the second largest ground in the Premier League, and could well help Spurs up to the level of financial firepower that the teams who regularly qualify for the Champions League enjoy.
As Redknapp mentioned, Tottenham have already moved to a new state of the art training complex in the last couple of years, meaning the North Londoners will have some of the best all round facilities in Europe when they move to their new stadium in 2018.
