That I don't know, but if the house is similar to traditional wooden ones I've seen in Austria and Bavaria, the balcony may well be at what we might consider the 'end' of the house as far as traditional UK design goes. Alpine roof design allows whatever drains off it to shed to the side, away from the access / windows etc. Presumably because of snow.. So perhaps the 'A' of the roof line as seen from the balcony allows a sight of Polaris from the end where the obstruction is low ?
Pure speculation of course !

Yeah it's a traditional "Chalet" Type of House with a high A Frame, and the Balcony is 1.5 meters extended from the Roof. So actually i got more than 180°
