Bungalow Floor Plans I Am Trying To Determine Best Way To Add Space To Second Floor Of My Bungalow?

I am trying to determine best way to add space to second floor of my bungalow? - bungalow floor plans

I have 1920, a bungalow, which is now upstairs 2 bedrooms. The room, fireplace blow for half of the house. There is another line of free roof over the main deck of the building or in the attic eaves on the front of the house. This space is ready to create walk-in closets and bathrooms. The back of the house has a lot of wasted space on the roof line. When raising the roof and Make It Out, what is the best plan for the receipt of the fireplace in the middle. Ideally, I would add, a bathroom and bedroom.
