Gothic window inset

[WoodlandDesign]

Anyone know how to achieve this Gothic wall niche detail which also contains a window? 

 

Tried superimposing the niche function over a window but that blocked the window from being clear to the outside view.  (See rendering)

 

Any input would be appreciated.

Thanks

Use a Wall Material Region to form the arched recess - with Cut Finished Layers of Parent Object checked.

Place a window under the Wall Material Region.

Here is a very quick one.

 Thanks for your idea.

 

I wasn't able to get the Materials Region option to give me the depth but was able to manipulate the niche to accomplish this.
