The big question about any interior is how to manage, distribute, and work with space. Don’t let all the possibilities frustrate you, though – once you take some key factors into consideration, it can be really simple.
The rule of thumb for how far apart to space your furniture is 3 feet, but don’t take that as a hard-and-fast law that can’t be broken. The spatial needs for a family with 4 young, energetic children will be very different from an elderly couple, or for a 5000 square-foot home versus a shotgun apartment in Brooklyn.
Always consider how much movement between pieces is necessary. You don’t want your sense of how space is supposed to work in a home to get somebody hurt.
For instance, households with children should banish prominent edges, and homes with older people who may have stiff joints will want to bring in higher furniture.
