Reminded me of a video I saw a few years ago about a woman that lived in a small urban house, and had it remodeled using industrial mobile shelving systems for the walls & cabinets. She had a murphy bed and bedroom furniture mounted to one set that made a bedroom; she moved one wall to close the bedroom and open a home office; and the last set of walls formed her kitchen; while the space remaining in the tiny house was for her couch/waiting area, her bathroom, and her untilies closet.
There are several other urban videos with a similar theme, but they are all single professionals with a tiny space. I was thinking that this kind of idea could also be used for a larger space, for a family. I'm thinking of finishing my basement, with a section having moving walls. On the two outer (non moving) walls, I'd have a large couch for a tv room on one end (plasma tv mounted to the moving wall, speakers mounted to the ceiling next to the couch) and on the other end I'd have a pair of desks, side by side, as a office/homework space. Behind the desks (on the moving wall) there'd be shelving for necessary books, and some cabinetry for other "office" gear. On the other side of that moving wall, there'd be more generic shelving for toys, as that "room" would be a play area; with the next "room" being a library, with looks of book shelving and a reading nook.
So from one end to the other, in a space about 14 foot wide by about 20 long; a office/computer workspace, a play space with toy bins, a library with a reading nook, and a tv room with a large couch.
And while that's what I'm thinking about right now, I'd like other ideas too. Different idea for purposed "rooms" that could be shared among a family or small group of roommates. Keep in mind that these "rooms" cannot be occupied at the same time, so a kitchen or a bedroom is probably not going to work, since there's almost always going to be someone that needs to use the kitchen or a bedroom while everyone else is watching a movie or the kids are playing, etc.
We just moved out of our Tiny Home a week or so ago, and I know a living room does not work well for a bedroom. In our case, we had a four bedroom Tiny House, but had (4) daughters and they did not want to move into it. So we enticed them with having their own bedrooms, but that left no bedroom for me and my wife. So we used the living room.
It might have worked as a kids room, but for us we had no privacy, and while it did play havoc on our sex life, by privacy I mean just having a conversation where we did not want the kids to hear, or having a place to just retreat from the kids. It was a real issue.
There was also the issue of getting good sleep as a couch or recliner is not the most ideal places to sleep, not to mention the cat waking us up, and kids passing through the living room into the bathroom. So when you remove space, there are definitely issue at play, but overall we liked Tiny House living. The only reason we moved back was because this big house would not sell, so why not just move back in. (We own (3) houses in all).
Story like this gets better after being told a few times. Or maybe it's just a tiny ad:
