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 a constant research on design themes and a constant training of composition skills.
