This research starts with the analysis of soft (digital) architectural outputs that are produced in generative modeling programs. Set by parametric relations, those soft outputs have high edit quality; for any "edit" they re-generate themselves. However, when converted to hard (physical) architectural outputs, those soft outputs lose their parametric relations and become irresponsive to their environment and time. The thesis project finds ways of an 'editable" architecture that will adapt itself for future demands. The project is an addition to the existing public library of Stockholm. By means of compression and expansion, the architectural programs of the library transfer the library to a more public space, from a street oriented library to an urban landscape oriented library, from today's open stack library to the future's digital library and book storage - book museum - or from 2007 to 2040.
