It will open its doors at noon on Friday (December 11) but we had the first look inside at the never-before-used Matrix machines, swish extended spin studio and interiors designed to motivate.
The brand is famed for its affordable membership prices and 24-hour opening times, but the license for this site is pending.
General manager Sarah Tate said she hoped it would be given the green light early in 2016.
In the meantime, here are six things we loved at Pure to get you sweaty, smiley and inspired at any hour.
Membership costs £34.99 per month and there is a special discounted joining fee of £15.
1. The lively, feel-good atmosphere
Pumping music, smiley faces of staff and a urban colour scheme greet members of this trendy gym.
The interiors are light, bright and airy and TV screens pumping out R n B tunes across the three floors give an added edge of motivation whether you’re pounding the treadmill or taking on the TRX.
General manager Sarah Tate said: “It’s a really good culture and vibe - it’s energetic, it’s fun and there’s a lot of excitement.
“Being in a new gym is amazing - and the brand new equipment is just like a playground for adults.”
2. Motivational slogans
Whether you’re just entering the fitness space or zumba dancing in the studio, you can’t escape these feel-good messages and images.
As you step inside, you’re greeted with “over achievers welcome”, while the quote “don’t think limits” could well be the extra push you need by the adductor machines.
3. Two SkiErg machines
Getting set for a holiday spent on the slopes?
Then you can hone your skills and challenge your muscles using this equipment, which can mimic the moves experienced and muscles used while skiing.
Sarah said: “With Pure Gym they are always looking for new things and, as the fitness industry evolves, we are always trying to keep up with it.
“With this you can move it side to side and do all kinds of things.”
4. Five stack with TRX
There are two pieces of this snazzy kit in the gym surrounded by plenty of space so you can get pulling, lifting and pushing.
Sarah said: “It’s multifunctional - you can do lots of different exercises and it gives an all over workout.”
5, Large free weights area
The pool has gone - apparently only 4% of La Fitness members said they used it - to make way for a spacious weights area in the basement.
This features an Olympic Lifting Platform with shock absorbent surface and special weights designed to be dropped after the move has been completed.
Meanwhile dumbbells weigh up to 50kg and there are 15 benches to lift from.
The number of squat and Smith machines has also been increased.
6. Spin and class studios
If you have a penchant for pedalling then one of 30 bikes lie in store at the extended cycling space.
Otherwise, the studio accommodates around 30 members and hosts more than 50 free classes with everything from Pure Yoga to Pure Bodypump.
All fitness staff, including managers, will be teaching sessions too.
