The private residence with doctor’ surgery designed in 1935 by Luis Plattner for doctor Roland Köllensperger and his family, shortly after completion had already acquired a somewhat ungracious nickname – the box. When it was refurbished in the 1970s, a pavilion roof was added to ‘the box’. Today, 35 years on, the building now contains two dwellings. Eliminating the pavilion roof, the Einzigart studio decided to bring the ‘box’ back to its original state and add another floor to what was a single family dwelling.
