This is a great example of what you can do with a fairly standard size closet. I love the drawers and shoe storage. Definitely a great use of space. Although this is only the man side of things, I'm sure there's an even bigger ladies version on the other side. But you could still implement many of the same ideas in a standard closet.
This is another effective use of not a lot of space. I like the shoe shelves, it would be more than enough shoe space for me (and Jason if I let him). I think my favourite part of this space is the row of drawers dividing the hanging spaces. Brilliant. They probably have it filled with beautiful jewelry, but I'm more practical, and would most likely shove socks and underwear in them.
Both of the closet updates going on in our house are on a much smaller scale. We're just trying to gain more functionality, not win contests haha, but it's fun (and important) to dream, and I think closets are a good place to do that.
