Bay window

Heya:

I was wondering if anyone had had luck building a bay window?

The hurdles Im bumping into are:
1. The porch around the outside has two 45degree angles. I can place the 90degree planking alright but it leaves two triangular areas that just wont play well.
2. Wanting to use different exterior (porch) and interior planks creates jagged "steps" which I cant hide unless I double up on the wall width.

If anyone has pulled this off I`d appreciate a pointer of two.
Thanks.

Yes.
The porch I was going for was on a corner and wrapped around the window vs running along it with the two small 45degreee spots on the porch edge, which caused problems. Also had the planks running at 90degrees to those in the pic.

Does the exterior and interior floor change at the wall? I had "steps" that stuck out.

That looks pretty nice )
