Once again I've been invited to a design test in order to better complete my job application. This showroom for high class residential buildings tries to explore a new idea of space arrangement: separation and connection of the different rooms at the same time without the use of internal walls or multiple storeys; this is to ensure an easy usability both for employees and for customers.TARGETS:_ unified ambient _ open-space one storey building _ different functions for different spaces _ keep secrecy and privacy of certain rooms _ visibility from the main road to the South _ constant connection with the exterior gardenCONCEPTS:_ spaces are separated and connected at the same time with the running “ribbon wall”_ all rooms are interdependent _ where needed privacy and secrecy achieved with double layer walls _ visibility through volumes articulations and wall transparency to south _ connection with garden given thanks to designed openings and wall transparency
