I looked into the nana wall and several other options as well --- They are really cool, but in the end, we determined that our house location and set up didn't warrant the expense of these. Now, if we had an awesome view, we might have done this. My recollection of this in terms of pricing for Nana Wall and some of the other brands: I believe it was about $800 a foot for this --- so for a 12' opening, it worked out to about $9600 --- I looked at several manufacturers and the pricing was all in that ballpark. Will your doors open to a patio, a screened porch? This was a concern for us in this decision. We ended up putting a screened porch, so the Nana concept would have been great, because opening the doors wide would still be within the screen.... thus no bugs, etc invading the house. If not, you might want to consider with lights on in the house and the doors wide open, you might get every moth in town visiting! Another consideration is how to stack the panels. In our plan it was working out to be awkward --- and the "stack" would have been in the way. Just make sure that if you go with these, you have that planned carefully... some of them can stack inside a wall, which is pretty neat. Another consideration to think about..... look back at your pictures linked.... the transition from inside to outside.... if you are trying to make a very open space, be careful of that little half step transition.... it looks like a tripping hazard to me. I would want either a full step down, or preferably a level transition there to open up the space. The top picture has a small step, which can be an ankle breaker! Finally, if you are trying to maximize your view through the house straight out the back, maybe consider an odd number of doors so the exact center is glass, not the door frames meeting in the middle (your bottom picture does this glass in the middle way). If you think about your set of 4 doors concept, the dead center part will be about 8" of door frame, vs. glass. If you use 3 or 5 panels, the center view would be glass. This is why in the first few pictures they show the doors open, because it looks way better open than closed. But in the last picture, the view is great regardless. And.... while I think the standard is to have the center 2 panels open on french doors, it makes furniture placement more difficult, so just make sure you've thought about it! Good luck would love to see pics of the view, etc! Rachel

Just over 7k for the doors which was the lowest I found. La Cantina was close but Marvin, Anderson, Jeld Wen were all over 10k. I did find that most dealers had no clue about their own products and gave me bogus quotes without really looking into getting me a decent price. I think they assume I am willing to spend big on these, but quoting me $10k when I could really get it for $7k is ridiculous. We are using an authorized installer to work with my GC to install the door...this gives me peace of mind AND adds an extra year on the warranty from Nana Wall. Hope to write back in two months with good stories about the doors and the instillation!

This room has a standard 8' plate height. The door height is 6'-8" and the width is just shy of 15'-0". Our clients love it. There's a opaque shade that pulls all the way across from one side, and the other side has a one piece screen that can also slide over the entire expanse of the door. It's a great product! Good luck with your project!

Unfortunately, the HOA is very strict about two panels only. The La Cantina options were sliding patio doors in XO configuration. What really increased the price were the installation costs since it's considered to be "new construction" rather than a retrofit. I am only looking for retrofit options that are OX and internal/external expresso color. Since I'm in CA, I don't think I'm allowed to do simple aluminum. I recently purchased fiberglass windows, so the preference is fiberglass but I wouldn't mind thermally improved aluminum or vinyl.
