Spaces in Mies's interior montages have the character either Miesian“flowing space”or“unitary space”, and in these montages both spaces indicate different expression especially in the relation between inside space and outside one. On the one hand, in montages for flowing space outside space is deprived of its aspects as outside space and becomes the extension of the interior space, and there is no outside space as the “otherness” to the interior space. On the other hand, in the montage that expresses unitary space has the outside space that symbolizes the outside as otherness and consist a schematic contrast between inside space as abstract space and outside space as space of otherness.
