I've considered two options. One is an Elfa closet from The Container Store (pictured). The other would be cheaper but requires more ingenuity. Ikea has large wardrobes that fit inside closets. We would simply remove the doors and slide in the wardrobes (but "simply" never turns out to be as easy when it comes to Ikea). It will likely be a big expense, but I find it a necessary one at the moment. The new bamboo floors in the den will have to wait.
