You don't have to buy matching chandeliers and pendants, though you are welcome to if you like a very coordinated look. But it is also definitely OK to buy fixtures from different collections, different manufacturers, in different finishes--that can help the spaces each stand apart and have their own personalities, in a way!

When picking out the fixtures for our new build I cut and paste (old fashioned I know) the pictures of the fixtures onto a sheet of paper to see if they complimented each other. Our house is open concept and all of the fixtures are visible with the exception of the wall sconces. They don’t need to match but coordinate.

Joy M, that's a great idea!

The dont have to be the same. They should just compliment one another! The same lighting in all of those different areas may cause you to become bored or frustrated with your overall design. Joy's idea to put them all together on one paper is a great idea. Please find below some examples of multiple fixtures and pendants from Shakuff below.
