Architectural Sketching

I see a sketch as a quick depiction of a complex set of concepts in a fluid form, allowing the present phase to materialize but still leaving room for further examination. 

Moreover, the sketch gives a vision of the final product, enabling the development  of the parts to be in harmony with the envisioned totality.  

Since results are quick and accessible, sketching allows for constant research on design themes and constant training of composition skills.
