Sexy Door Frames; They DO Exist!

Is that a door in that wall? Hard to tell without that 2" hollow metal or aluminum frame sticking off the wall. Lualdi out of Italy makes extremely discreet frames, hardware and doors. Above is the Rasomuro system that allows the door to me completely flush with the wall with just a slight hint of an aluminum frame. 

And even though it can only be flush to one side of the wall, it can open inward or outward by switching the hinge to either side.
Their Outline system holds the door off the wall while concealing the frame behind it...

And their Drive system is a very simple barn door...

You can navigate through the options by going to the website and clicking on LualdiDoors.
