The window slit 12 is a modified version of the window opening 11.

The main difference is that in the design of the upper part of the window solution, other moldings and cornices are used, which means the use of larger brackets, but the refusal of the castle stone in decoration.

We can say that this version of the window opening is minimized and is designed for windows on the first floor, regardless of the height of the floor and the used cornice or wall panels for the separation of the first floor from the others.
