Parasitic Design - Idea Formulation

I'm trying to identify Parasitism types within design but focusing on 3D.

1. Objects which steal energy or a resource from a source/host.

2. Objects which change the form of an existing object.

3. Materials which invade other materials.

4. Objects which attatch themselves.

'Las Palmas Parasite’ by Korteknie Stuhlmacher Architecten.Dutch Architects who have created a prototype of a prefabricated building attached to the roof of an existing warehouse. The building exists using the water and heating power of the warehouse and can be attached in a short time scale. Not only is it aesthetically pleasing but solves a lot of problems from energy consumption and housing space. Its a very interesting opportunity for a parasitic relationship within Architecture.

Micheal Rakowitz, Parasite. The product is a compact homeless shelter. The mass of fabric is able to be carried around and then rolled out. A tube is attached to the exterior ventilation systems on existing buildings. The product fills up with warm air and provides a temporary warm and waterproof membrane for the person to sleep in. Taking advantage of heat which is usually wasted and also making a thought provoking statement about the lack of shelter for the homeless within the city.
This is an impressive opportunity for design using existing sources, imagine a parasite which exists on wind or condensation or some other free source. The idea of the inflatable is also an interesting one. The air we expel is proven to be able to intervene in a Parasitic relationship and inflatables themselves definitely seem an extremely successful form of parasite.
