Pure architecture, for example, can be characterized by:
Balanced volume of composition
Canonical execution of the classic facade
Harmonious use of the color palette
Elegant form creation
All of the above
In my opinion, the most interesting parameter is the organic integration of architecture into the surrounding space. A well-integrated object will unconsciously attract the eye and become a natural extension of the environment.
Consider the example of a gallery and café project built in the midst of a scorching desert — it might seem odd. But no: the succinct and emphatically correct white volume of the building contrasts devilishly organically with its surroundings. Pure and tasteful!
