12' Tree Sculpture

We are basically building an interactive/immersive garden experience. The center point of the experience is a sculpture of a tree. We are looking for someone to bring our concept of the sculpture a step further, by exploring material options and ultimately creating drafting drawings for the sculpture that we can hand off to a team for fabrication.

Details:
The tree will be an outdoor permanent installation, about 9-12' in height,
The material of the tree must be weatherproof and translucent
The tree must be hollow so we can install lighting within it ( so it glows at night)
The material/color of the tree must be light/white so that it can also be projection-mapped onto
The tree does not need to have leaves nor does it need a root system that gets as thin as some of the images may imply
Timeline for fabrication is flexible; really is dependant on what material we decide to use and how long it functionally takes to build the tree
