Within the series of projects on porosity T?F together with ABT initiated the studio on structure of porous building. The studio aimed at methodical evaluation of the structural consequences of adding porosity.

Porosity in this case was dealt with in a context of high-rise and was defined by limited criteria: number of terraces, number of views, number of corner units and ant the amount of sunlight these units would get. These criteria would be the basis of the qualitative evaluation of the design. The more views, terraces and sunlight particular design provides the more porous it could be considered. Also the more real estate value it could deliver.

But how much does porosity costs?

Adding terraces and corner units results in the increase of the facade surface. Making holes in the building, or creating cantilever parts renders the structure more complex, heavy and, therefore, more expensive. By adding balconies, voids, terraces, corners the project developed a large number of iterations from the standard, straight and solid tower into ultimately porous one. A specially developed script would calculate the amount of steel needed to make the basic structure of the building.

Looking at the fantasy of the ultimately porous building and confronting it with the reality of its structure served as a basis of evaluation of each particular design.
