Add crown moulding to the living room, or update the trim around the windows and doors. Even just giving trim a fresh coat of paint will make it pop. Replace builder-grade hollow core doors with wood options. For even more of an impact, consider one or two doors with frosted glass inserts for a bedroom or bathroom. Update your closets with built-in shelving, new hangers or an updated light fixture. A current trend is a chandelier in a walk-in, which adds elegance in an unexpected place. Once you’ve started DIYing, you’ll find you won’t be able to stop!
