When you're looking for a door keep in mind the space that the door is going to encompass...Will these be closet doors? or Will these doors open up to my office or to my outdoors?
Contemporary means simple so don't get carried away with sliding doors everywhere you turn remember to keep this as a special feature in your home. However if your space allows you to use more than one set of sliding doors keep your furniture and accessories to a minimum because you DO NOT want the design to become to busy. By the way there are plenty of gorgeous door options that don't slide you just have to make sure your design elements work together and not against one another.
