I like having a separate bedroom. It has nice carpeting, a big bed, a clothing closet and blinds that make the room pitch black. The walls are isolated for heat and noise and the only window is facing the garden, not the busy street on the other side. No electronics to distract me, nothing to look at. The temperature is lower than the rest of the house (on purpose). It's really magical for me to sleep there and I have the best sleep. I used to sleep in the living room and it was terrible. Fan noise from the central ventilation system, lights from various electronic devices, noise from the street-side window, noise from the dishwasher and it was way too warm in the winter.
So yes. Having a bit more space in your home can raise your standard of living.
