The midfielder has made a remarkable rise since joining the youth set-up six years ago and has gone on to win the First Division title with Alan Archibald's side and gain international recognition with Scotland Under-21s.
Euromillions winners Chris and Colin Weir have pledged £750,000 to overhaul Thistle's grass roots structure and Bannigan is confident the results will be promising for the Jags.
He said: "Things weren't great when I first started here, there wasn't much going on. Hopefully with this money going in we can bring a lot more players through.
"It will help the teams right from a young age and hopefully through to the first team. We want to bring players through the system rather than having to buy players.
"I was just about to turn 15 when I joined Thistle, I played for the Under-17s. I had two years there, two years at 19s and then into the first team.
"There were maybe only five or six boys that were full-time.
"There weren't enough numbers for training and on the odd occasion that we trained with the first team, that was a bonus.
"Now we have got a full team in full-time and they can train themselves. They have got their own coaches and it benefits them.
"A lot of other teams are bringing players right the way through and that has to be the plan for Thistle rather than picking up players that have been developed by other clubs."
Archibald's side return to action after the international break with a trip to in-form Inverness Caley Thistle this weekend.
The Jags saw another three points slip through their grasps as Hibernian snatched victory at Firhill last time out as Thistle's frustrating run of results continued.
But Bannigan insists there is no need to panic as the Premiership newcomers target a return to winning ways.
He said: "If we keep playing the way we are playing, I am sure the results will come. We need to start picking up points, especially at home. There will be days when we don't play as well but win games.
"The results will come. We are playing well and that is important.
"It is hard having the break after a defeat like that but you have to remember that we have still got 10 points on the board.
"It is not a bad return at this stage of the season. It could have been a lot more but we are pleased overall with how things have gone."
