The project consists of the renovation of an office existing building of 10.402m², the redesign of the facade taking into account the overall structure, the renovation of the technical premises, and the optimizing of office planning. The building requires a new architectural point of departure; the new project is justified in light of the evolution of conditions of usage as well as regards energy standards. The idea of total flexibility is pursued throughout: through the uniform grid patterning of the facade paneling into 1.35m modules corresponding to the 1.35m modules of the suspended ceilings, and through the electrical and technical “irrigation” of the offices by means of raised floors. The building’s new image will form both out of restraint regarding the economy of means and the taking into account of the client’s expressed wishes and needs. Our proposition highlights generosity of space, light, comfort, transparency and wellbeing. The problem of energy will be approached subtly, with the aim of upgrading the efficiency of the facades and facilities “to measure”, rather that simply applying current regulations brutally. The building will be wiped entirely clean of all superfluous elements.
