During the renovation works on an ancient heritage building from the late 18th century on Viennas traditional Berggasse, a bricked up staircase was found. It led to a twelve meter deep, second cellar area with approximately 250 square meters. Located between Votivkirche and Sigmund Freuds apartment, this cocktail and underground bar is an aesthetical gem.

krypt.bar By BURO KLK - Sheet1Archeology in a Jazz Club

Historical investigations showed that it was a semi legal establishment in the 50ies and 60ies in an era of Vienna’s flourishing jazz scene represented by names as Joe Zawinul or Fatty George. So the generic „genius loci“ did not have to be invented but simply revealed.

krypt.bar By BURO KLK - Sheet2The circulation and dramaturgy of the cocktail bar starts at an undecorated, narrow entrance door that leads via an first basement level, containing the wardrobe and a mirrored vestibule to a „floating“ stair case, which suggests a touch of „Sunset Boulevard“. This pathway leads directly to the seven meter main bar. Several alcoves, a hidden booth, the smallest art gallery in Vienna and secret hallways surround the center piece and give the impression of a nearly surreal venue fallen out of times.

krypt.bar By BURO KLK - Sheet3Due to the strict constraints concerning the conservation of an historic building the whole building equipment and appliances were situated in a concrete floor plate and in a load- bearing trussing which was directly generated from the engineering requirements. The whole static structure as well as the ventilating pipes and further installations, were cladded in composition gold. The floor plate is covered with a layer of italian nero marquina marble manually laid in a herringbone bond. The cladding of the the bar counter was cut out of a massive block of Sahara noir laurent gold marble applied in a mirrored pattern, the counter plate was crafted out of massive American walnut.

krypt.bar By BURO KLK - Sheet4The furniture and illumination give the impression as if it was directly carried out of a museum of international furniture design. The famous platner arm chairs by Knoll, the candle light by Ingo Maurer or the Sofa DS- 1025 by Ubald Klug are arranged with the brand new bean bags by Alexander Wang for Poltrona Frau.
