Any minimalist parents out there?

Are you a minimalist at heart, but have to deal with the compromises that come with being a parent and spouse? How do you do it? Do you have a room in your house that you have complete control over? Are you constantly picking up after the kids in an attempt to clear the furniture and floors from clutter?

I suspect there may not be many (or any) people on fluther that this question applies to. If you happen to even know of anyone that fits this criteria, are you aware of how they manage?

There are really two parts to this issue:
1. Consumerism. Fortunately, my wife and I are on the same page. We purchase few, quality, useful items. We purchase used and sell as soon as we no longer need it. Our kids wear hand-me-downs and second-hand clothes mostly, and we donate our clothing when it is no longer used. We don’t watch TV, don’t have a gaming system, we worship the library, and do not set foot in a mall.
2. The minimalist aesthetic. Not even sure if this is what it is called. I like clean and simple. Nothing frilly or excessive. No clutter. My wife and I are almost on the same page here. But more importantly, this just doesn’t seem to work with kids. Clutter is what they do.

I have a tiny house (see #1 above), so a room isn’t going to work. I have considered investing in a storage system for toys and art supplies and putting into place a strong system that would encourage these storage units to be used. However, I have yet to find the best solution.

Sorry for the length and possibly useless question for most of you.
Summary: If you are a minimalist who is now in the messy tornado known as a family, have you found any methods for finding peace?
