A & A Team

Competence is the prerequisite for quality. 

Sound knowledge, instinct and good taste form the basis for all decisions and calculations. This certainty grants freedom in playing with the beautiful and the significant. 

Independence creates clarity, purity and freedom.
Discretion is a high good. It allows us to enter into genuine relationships - with people and with pieces of art.
