Principles

The purposeful strive of humanity for construction of ideal structures is eternal,

For guidance,

Marcus Vitruvius Polio, the legendary Roman architect who lived during the 1st century BC, had inscribed multi-volume text by the title De architectura, as the only treatise on architecture to survive from antiquity, it has been regarded since the Renaissance as the first book on architectural theory. 

In this text is coined the term FUV, long before this establishment appears,

it is inscribed that all buildings must have three attributes:

In Latin:          Firmitas        Utilitas     Venustas

In English:     Firmness      Utility       Beauty

Thus,

we KNOW and IMPLENENT the principles.
