No! I'm not a feminist, although I'm 53, single, never married, and have supported myself and lived away from my parents since graduating from high school. Many assume I'm a feminist because of my life-situation. So, please define feminist and I can better answer the OP.
Houses are not designed for large, much less multi-generational families. Same problem with vehicles and suburbia, where most Americans live.
It CAN be done, however, if all of the parties are "on board" to make many sacrifices. In NYC I know of three large families with 12, 13, and 15 children. The first family is very wealthy and have a huge house in Jamaica Estates, Queens. The second is super-crowded onto the second floor above the "church" where the father and grandfather are Baptist ministers. Dad built military-style four-tier bunk beds onto opposite walls and put a double-sided bookcase between them as a partition, forming boys' and girls' dormitories. Mom, Dad and baby sleep on the living-area futon that folds into a couch. They eat in shifts. The ladies use the upstairs bathroom and the men use the bathroom of the basement of the church where Grandpa and Grandma have a small apartment. If the authorities found out, they'd be in violation of occupancy, health and safety rules. The family with 15 jointly owns an entire four-story walk-up tenement building. Grandma, Grandpa and older unmarried uncle who is slightly mentally impaired live on the first floor. The big family occupies the second and third floors. The fourth floor is divided into three apartments. An uncle and his wife and baby live in the largest, a single aunt lives in the smallest, and the middle sized is occupied by three cousins of the mother's who are all attending various colleges. The basement is used for laundry, food storage, and a play room. They have a tiny fenced-in backyard with a garage just big enough for the 15 passenger van, and where they have a small, terraced vegetable garden, and a coop for six chickens. Ten of the adults and older teens work to pay the bills, but none of the women with young children. BTW, none of these families are Catholic!
