Dormer Cheek Windows? Correct name for planning?

[JP_]

How do you properly describe a dormer with a window in the cheek?
For a loft conversion I'll be doing, I want to create 2 bedrooms upstairs. The bungalow is long, running from front to back, so dormers will have to be on the side. Any windows in the dormer in the standard way will have to be obscure glazed, so I want to put windows on the cheeks of the dormers to give view to street instead of side.

Like this:

Or, maybe (a mansard style?) like this:

So inside, it will be like this (but without the roof windows, only wider and with a partition wall down the middle (property is about 6.5m wide, so probably 2 rooms at least 2.5m wide and longish (4m maybe):

I am trying to see if anybody locally has applied for planning permission to do this, but without knowing what architects and planners call it, I am struggling to find any examples!

More Googling and I found it, and they are called glazed cheeks!

and something in "Loft Conversions" By John Coutts (Google books)

Yeah - I understood exactly!

Any side-facing window on a first floor or above needs to be glazed in obscure glass, and with a top opener no lower than 1.7m above floor level.

Thus the desire for a dormer cheek window, rather than a side facing obscured glass one.

 

[tony1851]

If the dormer cheek is not facing the side, you're OK with ordinary glazing.
Don't know if there's any special name for it, other than 'glazed dormer cheek'.

If I want to build an extension with a window in the side, what is it called?

A cheeky aspect?
