As the club this week announced a major sponsorship deal for the 2013 season with lighting company LEDified, chief executive Michael Nettlefold snuffed out suggestions the club could return to its former home on a part-time basis.
The Saints moved to their new training and administration base early in 2011 and that is where they would remain, Nettlefold said, with planning underway to expand the Linen House Centre.
"In the context of where we're going to operate our training and administration, that will be from our new facility," Nettlefold said.
"We're working through that at the moment in terms of what phase two of the facility looks like.
"We haven't quite mapped that out. A lot of that's going to depend on our future requirements for sports science and a range of those sorts of things.
"We do have some land here available that was set aside for the next phase of the Linen House Centre."
Coach Scott Watters said there was no doubt the Saints' Seaford base needed to continue to evolve, but any additions needed to be well thought out and strategically planned.
"I think you need to be very careful about getting caught in an arms race," he said.
"What was probably relevant three to five years ago, there needs to be additions, but they've got to be smart additions.
"You see the jumps that many of the clubs have made even in the last 12-24 months," Watters noted.
"You do need to remain cutting edge to remain competitive, but at the same time it's not just about massive expenditure and bigger necessarily meaning better.
"We've got to be smart about the way we move forward."
The Saints are involved in planning discussions for Moorabin with a view to develop the club's former home into a community hub and a ground that could host VFL matches.
Following this week's sponsorship announcement, Nettlefold said the club was on track to make a profit this year after recording an operating profit of $631,135 for the financial year ending 31 October 2012.
