A three dimensional stand alone pop up assembly and method for making the same, the assembly comprising outer structural wall panels connected with an internal support structure having a spreader, center support element and base components. The assembly moves between a first position, whereby the support structure is folded within the wall panels of the outer structure, and a second position whereby outer structural panels are unfolded into a three-dimensional stand-alone pop-up structure supported in the open position by the internal support structure. The assembly utilizes an internal support structure which folds internally and alleviates the need for an extended base or protruding member. The assembly accommodates a variety of lighting and sound features and can be configured in a variety of three dimensional stand alone pop up designs.
