Instant spaces can be erected for temporary use. Walls and roofs can retract to transform a space from indoors to outdoors. Structures can transform to create exciting venues for performances and entertainment. Windbreaks and sunshades can respond to changes in weather or time of day. Expands from 9.5 tp 30.
