Not if it is supported by the porch roof structure adequately. But this is a very DIY looking addition so that’s probably doubtful.
A bay window is is still a bay window if it has a walkable floor. Most Victorian styles, which this one has some features of, would have bay windows at floor level prominently at the front of the house.
It is both but more of a bump out because of the sructured walls and roof.
I kinda thinks you jest.
The overhang barely supports itself.
If it is supported by the roof it still is a bump out.
I have provided even more pictures of architechural bump outs.

I will also say that any bump out must have a design and approved for the support it will receive. That would not be by the roof.

Oriel windows with brackets in Oloron-Sainte-Marie, France.
Oriel windows are a form of bay window which project from the main wall of the building but do not reach to the ground.[1]](http://en.wikipedia.org/wiki/Oriel_window#cite_note-1) Supported by corbels, brackets or similar, an oriel window is most commonly found projecting from an upper floor but is also sometimes used on the ground floor.
Oriel windows are seen in Arab architecture in the form of mashrabiya. In Islamic culture these windows and balconies project from the street front of houses, providing an area in which women could peer out and see the activities below while remaining invisible.[2]](http://en.wikipedia.org/wiki/Oriel_window#cite_note-2)
Me thinks a modified dormer:shock:
On a gable end.
My wife would love to have a place like this for reading, ME TOO!
You all can call it pretty much whatever you want, it don’t change the fact that it still is a bay window.
Personally I call them bumpouts.
Do you have an issue with that terminology ?
Let me really mix it up and call it an enclosed balcony.
How about tandem room ?
I’ll settle this!
From now on when we see the rare design such as posted we will call it a
Bumped out wall with a Bay Window and Oriel features.:mrgreen:
I have no issue with any of that terminology, but when you use it to describe a bay window you will be incorrect.
^Wrong^… ^Right^ … ^wrong^
Said modified?? that pretty well covers it all don’t:mrgreen:
Right… Wrong… Huh.
**Bay window
**
The window of a protruded bay
The windowed bay, rising from the ground for one or more stories

A** bay window** rises from the ground for one or more stories**;** an oriel window is supported from below with a corbel or bracket. Oriel windows are always sited on upper floors.
Bow window: curved bay window
So let me get this straight in your picture Marcel. The bottom windows are for a bay window and what are the top ones?
I know ORIEL!
Oriel windows are always sited on upper floors.
I have seen many bump outs with windows added that are not classified as OREIL’s LOL
But to confuse you even more ORIEL windows are a **form of Bay **Window thus the reason I could not correct Nick.
Actually, what Marcel pictured is just a bay window, upper and lower. Bay windows can actually stretch through all floors of a multi-story building and they are still just a bay window.
Oriels are not limited to upper floors either, though that is typically where they are found. What makes an oriel windows distinct is its supporting structure coming from the wall not the ground below.

But those are not designed to be more than several feet past the wall covering.
