The Casa Bubble houses are not meant to be permanent structures and are actually being marketed for temporary exhibitions, temporary eco-tourism structures, and special event occasions. Each module is made from a recycled/recyclable PVC material and leaves little impact behind on the land that they touch — just be certain that you are not crushing any endangered foliage, and that set-up does not require any major removing or clearing underfoot.
If you have a large enough space, you can set-up your own temporary bubble tree empire. The various modules can be added to indefinitely.
