 The corners of the building are accentuated as avant-corps with shadow joints and lesenes.The school was constructed as a 4-winged structure around an atrium similar to the Samsøgade School, completed a few years earlier.However, in Læssøgade School the atrium roof is at the same level as the roofs of the rest of the buildings and not at the 1st floor like in Samsøgade School.
