Wow, that's impressive. Sure doesn't leave anything for privacy though!
I'm guessing you need a pretty good security company too - no stopping someone should they choose to break in!

The cantilevered beams above it would need to be very stiff so I suspect they would be structural steel. An open corner severely reduces lateral bracing of the walls so the structure would have to be designed by an engineer.

You want to spend 100K on a door?

Sanford W., thank you for your educational, non-judgmental response. :)

This door is cool to look at; however, it doesn't offer any function that two traditional sliding doors couldn't offer (assuming, of course, that you don't move your grand piano out to the pool regularly). So I personally wouldn't want to pay a premium for this door.

I'd also want to know what it looks like when the door is closed (which will be most of the time). I suspect a metal line of some sort will be necessary, and that'll ruin the look.

I think it'd be one of those things that would seem really amazing for about two weeks ... then you wouldn't think of it for weeks at a time.

If you're really into this idea, I'd consider going with the regular "disappearing" doors -- not the corner doors, but just a straight run. They're a splurge, but they are really cool. We once rented an oceanfront condo with this type of door, and it was nice to open the doors in the late evening and essentially "meld" the living room with the screen porch. Very, very cool during a lightning storm.

OR consider going with a corner window seat with no-seam windows. While it's not the same thing as you're showing, it would be a nice-looking little seating area and would give something of the same feel.

I can see the appeal in having this kind of open corner. I've only seen this in a house once in real life; it was a high end mid-century house, the room led out to the pool and it must have been great with everything open. Unfortunately, the sliding doors were no longer operable. I expect the technology to maintain the structure of the frames has improved over the past decades, though. Good luck!

I could not find sliding glass doors but found this option. Either look is unique.

They are gorgeous doors and we are utilizing them in our new build. We were choosing between Windoor and PGT, went with PGT for energy efficiency and overall door/window package. Our house will overlook a lake and feature a pool/spa as well, so we wanted an indoor/outdoor feel. 10' tall. You can get glass that is hurricane rated so a burglar would not be able to break through. Expect around 15-20k, depending on how long the opening is. Best of luck!

This is probably a stupid question...but I am assuming the doors are open in the photo, and slid into the wall like a pocket door? And that there is actually a corner piece of wood where the two pieces of glass meet? At first glance I thought it was some sort of L-shaped glass...but that's not possible, right, lol?

Very cool look, BTW!

We are having a corner sliding door installed on our new house. It's an option for several builders here in az. Cost about 20k no matter which builder we looked at.

Sanford's comments are right on the mark. Corner bracing is a standard technique for ensuring the stability of a building. In seismic zones and high wind zones proper and sufficient lateral bracing is a critical code requirement. If one builds in an area with expansive and moving soils this is also an important issue. If one removes the corners where wall bracing is normally located, then sufficient lateral bracing must be designed elsewhere, along with the necessary connections to the foundations.

A second story above such a corner means even more structural calculations and connections in order that the second floor live and dead loads can be properly transferred to the foundations.

Stop and look at these corner doors for a moment. What do you suppose is supporting the door head? The only answer is a cantilevered beam in both of the perpendicular walls. Depending on the span distance, using cantilevered wood beams may or may not be possible, thus requiring steel beams or tubes for sufficient strength and rigidity.

In other words, the cost of these doors is much more than the cost of the doors!

Right on, Virgil! I would expect a boatload of steel to be necessary here and would worry that the potential problem with not having enough structural support may not be readily apparent at first, but would show itself later with settling or age, and then a tiny bit of droop would mean that you can no longer open the doors / the doors break.

I avoided a simple corner window for this reason in my build - and have concrete in the corners - this is taking that to an extreme! (And yes - it looks awesome and I am a MCM fan!)

How much did this end up costing?

Two Florida area builders we were dealing with offer this as as option. The glass is hurricane rated on the ones we choose.

Looks like Pulte also offers them in some of their Mystique Design homes.

Curious about the costs of these. Stunning!

Figure about $2500 - $3,000 a LF for the door itself not including the install and majorly engineered framing required to carry the weight of the structure above.

How much for this option in Pulte home (FL)?

"How much for this option in Pulte home (FL)?"

Only way to get that info is to ask Pulte but more than likely a minimum of 1.5 what it is worth and not sure I would let a tract home window installer even think about installing one of these...........................

I opted for zero corner sliding glass door with Pulte. The cost to add this was $10,000.

What size zero corner did you select, drish?

Jonathan, it is 12 X 14. It will look something like this.
