The proposed 1547sq m, two- to three-storey facility, named "Building 13", would include office space and a cafe-bistro.
Remarkables Park director John Porter said it would be a "good facility" where parents could drop their children before going shopping.
"At the moment, we don't have much for children and this building is going to provide options."
He said construction would start "the minute consent is granted", and expected that would be early next year.
Remarkables Park was last year granted consent to construct a building (also known as Building 13) to house a Chipmunks children's playcentre, a cafe and apartment accommodation to help cater for expansion of the centre's existing Southern Institute of Technology (SIT) campus.
Mr Porter said Remarkables Park was still looking to develop the original site, now renamed "Building 14", but could not yet confirm what would go in the building.
Remarkables Park on Wednesday confirmed to the Otago Daily Times SIT still had plans to expand its campus in the park.
The proposed facility will include a 15m by 6m swimming pool Mr Porter said the new pool would not compete with the nearby council-owned Alpine Aqualand complex, opened in 2008.
"It's not a leisure thing - it's purely for teaching children, and I'm talking right down to babies ... it's a relatively shallow pool." The Wakatipu Swim School would operate from 7am to 8pm seven days a week on the lower ground floor area. On the 645sq m upper ground floor level, the Chipmunks business would consist of a large open play area, two smaller playrooms and a licensed cafe-bistro. It would operate seven days a week from 7.30am until 11pm.
Intended as commercial office space, the 439sq m first floor would extend only partway along the building, creating "a more open feeling" in the play area below the remaining space.
The site is south of the Remarkable Park Town Centre's Von House and would provide 34 parking spaces.
