A Peters's Profile

You could consider painting the windows and trim a color that better complements the stone. The facade needs work, but maybe the stone isn't the problem.

I like option 3 as well, it gives you the most usable living space and gives you two exits out of the bedroom.
If you don't need that cupboard though, you could remove that and shift the bedroom in that direction.
And as far as building codes go, others are correct that in some places you need 2 forms of egress for it to be considered a bedroom legally, but there's nothing to prevent you from sleeping in an office or den. I work for a city and whenever people come in for permits and we can tell they're using a room without a window (or too small of a window) as a bedroom we let them know that the plans can't be labeled as "bedroom". If the plans say "storage" or "office" or "den", then we're okay.

Good idea. I don't even know my wife's number.
