In connecting the three buildings as one, Bovenbouw dramatised breakthroughs in the party walls as essential spatial components, creating openings and entrances through what were chimneys or mantelpieces in the past life. Fireplaces present in many rooms throughout the building were also transformed into entranceways and connecting structures between rooms, motifs that are both functional and decorative elements.
