Description from Danish Design Store
Shortly after Arne Jacobsen won a competition in 1961 for his design of the National Bank of Denmark he was contacted by the owner of VOLA A/S, Verner Overgaard who introduced his proposal for a new type of wall-mounted mixer tap. He imagined a design where all the mechanical parts of the mixer are hidden leaving only the handles and spout seen by the user. At the time this was a completely new concept, but Jacobsen realized that this idea combined with his functionalistic approach to design could be developed. With that basic principle in mind, the simple and concise VOLA design we know today was conceived.
