nanoBuilding concept How things growBy multiplication of basic elements
bricks, cells, molecules,...using a plan that is either
extrinsic (building plans), intrinsic (instructions contained in
DNA), or combined (bonsai)
forming functional parts in their final size (a house) in growing size and functionality

nanoBuilding concept Growing facilitiesCommon practice of construction is
by sequential multiplication and composition of a variety of macro-level building
elements, produced by traditional ways of material
treatmentour goal: to mimic the natural way
using nano-level building elements

Nanotechnology in ConstructionMaterial refinment (e.g. 3-6x
higher strenght of conrete using nano-silica, self-cleaning & antifogging using TiO2)
New materials with better properties – carbon nanotubes (CNT), 100x strength of steel

nanoBuilding conceptThe process
1. 3D solid modeling2. 4D modeling (slicing &
sequencing)3. site preparation4. building & control5. functional testing
![Page 13: I came to the farm to see how things grow And I learned some things](https://reader036.vdocument.in/reader036/viewer/2022062410/568159e3550346895dc72e82/html5/thumbnails/13.jpg)
nanoBuilding conceptThe process
1. 3D solid modeling define detailed solid geometry define parts of the model (3D
areas), with specific material properties (strength, friction, conductivity, to form utility systems like water system, sewer system, electrical instalations, communication system etc.)
![Page 14: I came to the farm to see how things grow And I learned some things](https://reader036.vdocument.in/reader036/viewer/2022062410/568159e3550346895dc72e82/html5/thumbnails/14.jpg)
nanoBuilding conceptThe process
2. 4D modeling defining supportive structures where
necessary (for any vertical holes) slicing according to the thickness of
the nano layers sequencing – defining the sequence
and the default time for each slice

Conclusion
I belive the question is not if (bio)nanotehnology can meet the defined requirements, but when.
The proof of concept exists!
