Any special name for a house or flat with an indoor balcony, please?

[Mehrgan]

Hello,

I was wondering if somebody could give me any related words, especially in BrE. Does the name change in case whether the second floor, with half-height walls overlooking the sitting room, have bedrooms or not? Is there any such name as 'loft flat'?!
