The 'Every Teardrop Is A Waterfall' star said that the group wanted to make sure the tracks translated well to a live setting.
Speaking about their secret rehearsal space, nicknamed The Beehive, Champion told Q magazine: "It's like an old village hall. A big space where we can play together.
"Often when you're making an album you can become alienated from one another in a studio environment.
"The Beehive was a deliberate move to get us playing together so we could get a feel of how the songs would sound as a live band as we were recording, instead of waiting until the record was done and then going out on the road."
Champion also confessed that the band will probably work on their new record right up until the last minute, saying: "We'll keep going until it literally has to leave to get mastered and pressed. They'll have to wrestle it out of our hands."
Coldplay's fifth studio album is expected to be released on October 24.
Frontman Chris Martin reportedly registered new song titles earlier this month, including one called 'Mylo Xyloto', which has since been speculated to be a contender for the new album's name.
