Tower Window

You all know I've been toying with the idea of a little offshoot tower on the third floor. Nothing huge, just a spot to set up a telescope.

So it isn't exact, and mine definitely won't look just like this.  But this is similar to what I want to do with the third floor of the tower.  Just to give you all an idea.

I got the picture off Pinterest but there wasn't any link I could go to to credit this incredible piece.  If anyone knows who it belongs to I'd love to visit their site. And credit the picture here of course.

Update: Tiny New World tells me this wonderful piece belongs to Peter over on DeviantArt.

This differs a bit in that I want the supports to rest against the brick of the tower rather than plaster for the extended third floor, but third floor being larger than the staircase 'base' is something I'm going for.

I probably won't have the elaborate beam work on the body of the tower, though it would be very cool if I could manage it.  Maybe echo it on the second floor of the house?  I won't need the chimney or the squared off bay windows.  I want to use a Houseworks Casement window that I made Tudor on one part of the third floor.  If I get really ambitious I might do another.

I love the steep slope of the roof but its a little too 'fantasy' for me so I'll probably go for something slightly more shallow.  But that little offshoot tower...

Which I still have no clue what that's called.  Does anyone know the technical name of that little tower?

That's what I want to do with the window I got.  The small Victorian bay window.

I think I'll end up microwaving it and taking it apart to make casement windows for it.  And making it a bit shorter.  But window's roof angle is similar to what I want for the main part of the tower. The inspiration picture has the type of roof I want to do on the WQ Retirement cottage, that slate look.  I'm collecting cereal boxes in order to get varying thicknesses of cardboard.

I think it's doable.

What do all of you think?
