We’ll be using every inch of space in our new house efficiently, and this is why our developer recommends using sliding doors and pocket doors…they slide rather than swing, and this saves a bit of room.
Below are examples of interior sliding doors and pocket doors (which are even better, as they actually slide in between the walls, saving even more wallspace). We’d probably stick with a neutral color or white, rather than a dark wood, but you get the idea:

Sliding glass doors to the patio outside come in all sizes and are multi-functional: not only saving space, but allowing a great deal of light into the house. We’ll have at least one of these in our kitchen, but possibly another one in our bedroom.
