Grafting is a horticultural technique that combines two plants by inserting the tissues of one into another. This process inspired the architectural technique of post-fabrication in order to develop the structure of a building. Through the use of new and unprecedented construction methods and materials, the Graft tower consists of an interlaced mesh-work of structural columns with connecting fingers spreading out to the plazas below. The structure grows by joining inosculate fibers around the basic skeletal frames of the commercial and housing units that resemble pods or seeds within the web.

Influenced by sunlight, rainfall, and wind dynamics, the organic structure weaves together to form a twisting tower that takes advantage of natural ventilation and cooling, with the housing pods positioned towards the west. Water is collected on the underside of the pods and is dispersed though the open framework into the vertical farming that grows throughout the building. The result would provide suitable conditions for plants to grow sporadically as they are able to find water and sunlight, as the residences help to maintain and assist the agriculture to grow.

The artificial photosynthesis skin panels that produce liquid ethanol support the energy demands of the building. The ethanol is distributed through portions of the vascular system of the building that also helps to manage the condensation problem at the site location. The faceted skin also allows a large variation in the electro-chromatic vision panels. The buildings structure and vertical framing is subsidized by the eco-tourism hotel. In the end this building not only aspires to become an epicenter for commercial activity, but also wants to support the San Juan community by providing water, food, and energy.
