Sky Sports were shown around the new facility at Lancing, which the Sky Bet Championship club hope they will be able to open next summer ahead of pre-season.
Brighton boss Oscar Garcia admitted that the plans were one thing that attracted him to the club, after joining in the summer.
"I think it is one of the best I have ever seen," Garcia told Sky Sports.
"I want to see all the facilities when it is finished - it is an attractive thing for everyone, for all managers and I wanted to work in a place like this and we are happy because in a few months this will be finished."
Brighton chief executive Paul Barber believes their new training base will be something to be proud of.
"This is a phenomenal facility," he said.
"It will house all our football operations, medical facilities, educational facilities and gymnasium, 13 full size pitches plus an indoor facility.
"We are very proud of what we are doing here and what it will do for the club in the future."
Barber insists that a new training ground was essential for the club.
"This is about the future of the club, both in terms of the young players, attracting them and developing them and getting them into the first team but also about attracting first-team players themselves," he said.
Building work started in May and executive director Martin Perry says the club need to make sure they finish on time.
"We are absolutely on programme because completion is due on June 27th next year and players are due back on June 30th so we have three days to get it right," he said.
