The 125 CLUB is a historic member's club within THFC. Its members include Joe Lewis (the co-owner of the club), club directors and former players.

Thunkgood was commissioned to conceive an interior design concept for the 125 Club's new private box at the new ground, as well as a 125 Club logo and identity. The selected concept melded Spurs' past with its future and included designs for the box's dining, kitchen and lounge areas.
