Greetings!
Since the standard to make an interior design with the requirements you have is that the environment has a minimum height of 4.60 m: I have thought to design for you two variants: one with the height according to the standard 4.60m and one with the current height 3.80.
VERSION 1 H=4.60
Since the space is abundant, I thought of positioning the bedroom on the first floor in order to create more privacy, while the cooking, dining, the living room and the service area to be on the ground floor.
The bedroom will be accessible through some stairs and there will have a huge wardrobe, a reading area and a woring table.
VERSION 1 H=3.80
In the entrance will be a wardrobe for hanging the worn clothes, direct access to the cooking&dining room which continues with the living room. The bedroom is raised 0.7m (above the ground) in order to create more privacy and in the end part of your space will be placed the service area.
I wish for my design to allow you to move freely and space becomes part of your life!
