You have your home theater, and you’ve got your game room, your bar room, your home office, and now all you want is a little peace and quiet. What you need is a Zen room—a calming space to relax and recharge. “People are very much affected by the surroundings they’re in—their mood, their wellness,” says Rina Okawa of ZEN Associates, a landscape- and interior-design firm with offices in Boston and Washington, D.C. She describes a Zen room as “a personal and private space surrounded by beauty that can lift your spirits up, refresh your mind, and revive your five senses.” “Especially with all that chatter out in the world,” says New York–based interior designer Charles Pavarini III, “we need a space where we can realign our thoughts, our energies.”
