An extensive apartment in the centre of Padua has been converted into a medical legal office. The dark and long central corridor has been totally renewed through few but significant signs. The ceiling has been lowered, in order to install all the new technical plant, and that gave the occasion to design a series of cuts and voids with “L” shape to host all the lighting system. The “L” shapes, unify all the existing spaces and define small waiting spaces for the patients.
