I'm with Ria, and would MUCH rather be warm than cold!
The living room here is double aspect, we have large, almost room-width patio doors at one end, facing SW, and a window at the other end, so always get the sun from somewhere

The kitchen-diner has the double aspect windows, as does our bedroom, which is directly above the living room and exactly the same size.
Our house is lovely and light, it was the first thing that struck me about it, when we viewed on a January day!
