I’ve made this as my BA graduation project. In our “century of loneliness”, different age groups often choose to or happen to live separately. We have large living rooms with nuclear type of family (2+1) to occupy them.
This drawings are concept design for a house where senior family members could live comfortably with younger ones. House has large comfy kitchen/ living area on the ground floor. Top floor (mezzanine) is kept in a bit more hip style – and has work area & bedroom & some couches and TV.
