An old building dating back to beginning of 19 century in Paris is the witness of Sustainable Development. The railway station developed from its initial site from a small connection between Paris and London street (St Lazare area to few next railways stop and terminal station at St Germain, which is not far from the Seine River. Since the builind was nearly unchanged. Few adaptations and scopes that came later (from 19th century to 21rst century are transformations for the passengers and good trafic flows dynamic. Sustainable development is just about building old new and keeping in a contibuous track between the past and the present for the future generations. In such a way, one can expect to preserve old building and build by transforming them, recycling them, giving them a new or different life or a diferent function.
