Try EasyClosets.com and play around with designs for a "reach-in closet," which is what you have there. You can customize the layout of shelves and rods and get something that fits your wardrobe and your pocketbook.

Do you have California Closets?

The possibilities are endless!

It depends on how you want to lay things out and what is important to you. I would suggest using the small walk in for your hanging storage with a combination of long hang and double hang and then use that nice runway side for adjustable shelving, drawers, and shoe shelves.

I'm not sure what those sliders go out to, but if you want to keep the area always looking clean/presentable, you could do like a large armoire style closet.

As I don't know your budget it is hard to recommend a source. I would strongly recommend California Closets as they are good quality and reasonable. If you want true luxury consider Poliform. If you have a good GC they can build it all out with millwork and rods to your specifications. Good luck to you with your project!

So, we decided to do a hybrid - Mixing the ELFA drawer system from Container Store with custom millwork and rods from our GC. Will post when finished!
