Active Northumberland gave a sneak preview of the site ahead of its scheduled opening in the autumn.
It will house a five-lane, 25m swimming pool, a teaching pool, leisure pool and spa facilities as well as a new fitness suite, cage and reception area.
There will also be a new sports hall, indoor bowls and a sensory room, while outside there will be a 3G full-size playing pitch, play park and trim trail and parking for 175 cars.
The new swimming pool and fitness suite is expected to open in summer 2021 and the new centre is expected to be fully complete and open to the public late 2022.
Here are 16 pictures to whet the appetite...
