   This came up over on JLC. One of the guys there has one in his house. Apparently you need a bigger header than you might think.

   Why would that be? header size is determined by the load carried ABOVE the openning, and the openning size, not by the openning fixture

   I know that the panels hang from the top track if that makes any difference.

   I see - that adds some weight to the looad, but more important, it means alignment is critical so you have to design for no deflection

   I'm not sure I could show someone around my house and say "this is my Nana wall" with a straight face.

   IIRC the whole thing hangs from the top of the opening, and the openings can get pretty wide. Been a couple of years since I read about them...

   How wide ins that door, and any idea how much that door costs? I'm thinking about something similar for my house.

   I think the one we are installing is only 8 or 9 feet. I just found out about this last night, and I forget the exact dimensions. The door alone cost a little over $13,000.

   figure $1500/ft, which is consistent with the price these people paid.

   Is that $1,500 per lineal foot?

   I think that's sq/ft. Pricey system.

   yes- I would budget $1500 per linear foot for the door purchase only. Install extra.  Customer above had a 9ft door at $13,000 is slightly less than 1500/ft.

   While Nanawall was the first door of this type I remember seeing, they are not the only manufacturer. Marvin has one as well, and it won't have to come from Germany.

   Every house featured in Dwell Magazine seems to have them. Looking at the way they fold out I would imagine that they have very low tolerances for uneven floors and rough framing.

   I like the idea, but have never lived in a climate where you could leave one wall of your house open without various things you didn't want coming in.

   yeah, the addition is on a slab, and the opening had to have a channel formed into it for the door to sit in. Not sure why, but it's already been done. Also, the header was sized with this door in mind, so I assume it's large enough. I didn't have anything to do with the framing, so best I can do is assume.

   John Walker, a poster from Australia did a thread over at Quittintime about one of these.  I hunted for it in his picture threads but couldn't come up with it quickly.  I've emailed him about this thread-maybe he'll show up and give you some information.

   Best of luck.
