Once complete the revamped, £15m stadium will have three new stands to house an extra 6,000 fans, boosting the total number of seats to around 18,000, giving it the capacity to host big games such as a PRO12 final or Heineken Cup quarter-final.
As work gets underway - and with Ulster making an unbeaten start to the season - Best said it shows the club's plans are coming together.
"It just shows the ambition of where we want to go," he told UTV.
"We want to be able to host home quarter finals and home semi finals and that's what it's all about.
"It has been a bit of a dream that's been coming for the past five or six years, of trying to put things here in place, starting with the new stand and also the signing of players and getting key, influential home-based players to stay and it's now starting to bear a little bit of fruit.
"It's only the end of November and we haven't won anything yet but this shows real ambition for the Ulster branch and as players we hopefully match that ambition."
It is expected the new grounds will be completed by September 2014.
