     ”Utsidan blir insidan och den röda tråden löper vidare; från de bastanta kraftfullt röda sittmöblerna och den skulpturala mörkt linoljefärgade ståltrappan med sina tvinnade trapplopp till den lekfullt utformade belysningen, lätt, sirlig och grafisk”, skriver juryn i sitt utlåtande.

     "The exterior becomes the interior and the red thread continues from the bold, powerful red seating furniture and the sculptural, dark linseed oil painted steel staircase with its twisted flights of stairs runs to the playfully designed lighting: light, airy and graphic," writes the jury in its statement.
