It's not the window,

               but its frame what counts...

"You can put a window worth thousands of dollars within an openning, but it is the frame, that 'concrete skin' surrounding it, which in the end adds value to that view..."  

This is a high-end residence renovation which brings traditional origami (also papiroplexia in Spain) as a strong reference.  

By bending and folding, new versions of window frames appear;

moreover, techtonics, architectural skin and language are put into question.

1,000 square feet are added to an existing house (formerly 3,800sf).  This means:  a new Masterbedroom (600sf) and new entrance to the home.
