The aim to materialise the atmosphere of 'inhabiting', and more specifically the one of 'inhabiting in Volos', is the trigger for the spatial research that consisted our thesis. 'Inhabiting in Volos' is an intimate course of action for us, performed on the verge of the automatic and unconscious. Wanting to get an augmented consciousness of it, we turn to other people's narratives of inhabiting. So, we are led to form some personalities and dramatised practices of their inhabiting. These were the starting material for the spatial research. Making use of the perceptual content of the verb over the energy and the bodily experience of doing, we shape the practices. We set our main compositional principles and from the combined shapes we extract spatial unities for each personality. The orchestration of practices in a plot, provoke us to assemble the personalities in a single structure. Basically, we aim for an assemblage of snapshots of inhabiting. In this way, we provoke the confrontation of the intimacies and to achieve a new coexistence balance, we are led to a compositional process, which result is the 'boulder'. The assemblage of practices in a materialised story. Principal tools of the whole compositional process were the bidirectional relation between writing and space formation and the tactile processing. The experience working with materials and objects contribute to an associative transfer to the real space. Reading the materialised shapes leads to the writing of the practices. Correspondingly, reading of the practices  directs the spatial composition. This bidirectional process can potentially generate new practices and space all the time. The boulder is the pause at the stage where a single structure has emerged and the defining of this last spatial assemblage.
