ᐅ Ridge line direction

Hello everyone,

I have an important question:

We are planning to build a second floor (attic) for our single-family house.

Now the problem: You usually see houses where the ridge of the roof runs along the longer side of the house. However, according to our plan, it would be the opposite.

Our house would be about 10 x 8 meters (33 x 26 feet), with the longer side running from north to south. The issue is that to the east (more precisely southeast, but I’m saying east to make it easier to imagine) there is open farmland, and beyond that, just fields. So I would like the bedroom on the second floor to face east, with the largest windows there (to enjoy the nature view from the bed). This would mean that the roof ridge would not run north to south but east to west so that large windows can be installed on the main wall of the house on the second floor facing east (and the staircase can also be positioned reasonably).

My question is: What is the disadvantage of having a roof ridge that runs along the shorter side of the house (in our case, from east to west)? Why don’t you ever see this? Is it much more expensive? Or just not practical?

Sorry, I’m completely new to this and just wondering...

Thanks for your answers.
