Here, the classic question of the rear extension to be replaced is limited by the modest budget and expansion possibilities to: the rear elevation. All answers here are given in the rear metre, over the entire height. The unnecessary structures are demolished and replaced by an "interior terrace" on the ground floor and a tablet on the first floor that offers several advantages: the raised ceiling provides more light in the living area, the bedroom gains a sitting area, and a delicate, discreet link is created between the ground floor and the first floor. It also introduces a larger size. Something we always seek, however small its scale. The rear façade is fully glazed. Transparent or oceanic, according to the logic. No giant glass panes but tailored to the size of the working-class house.
