The whale pool and playground in New Brighton should be open by summer.
Planning work is under way on the design which the community will be able to make comment on in the next few months.
Signage went up on-site last Tuesday to let people know that the project is under way.
Said Development Christchurch Ltd chief executive Rob Hall: “This is just one aspect of the plan to regenerate New Brighton. We have also been undertaking work to revitalise the commercial centre of the suburb, support wider community initiatives and develop the hot salt water pools.”
DCL was set up by the city council in 2015 and is leading the New Brighton regeneration project.
“It is good to be starting on the playground,” Mr Hall said.
Construction is expected to start in September and finish in November this year.
New Brighton Business and Landowners Association head Paul Lonsdale said it was “fantastic” to see the project under way. He added it was important to remember it was part of a broader development strategy, including street regeneration and the hot salt water pools.
Funding for the wider development of the hot salt water pools project has been included in the city council’s draft annual plan 2017/18, which will be open for public consultation soon.
Once residents have had their say on the proposed city budget for the year ahead, the city council will make final decisions at the end of June.
