We just bought an older house made of blocks (not sure what you call them but not wood frame) and would like to open up the top floor to have just a kitchen, dining area, living area and a toilet, no bedrooms.

The current owners enclosed the large balcony but it's technically not legal so it might need to come off one day. I have attached the current floor plan (in centimetres). The main request is to have (at least) the living area close to the large balcony wall as this is the nicest view (facing west). Small balcony is facing east. The north wall is a shared wall so can't have any windows. We are hoping to increase and add windows and sliding doors, break walls to have as open space as possible to bring more light in.

Any ideas?
