This apartment is located on the second floor already had a place for a fireplace and the height of the ceilings was 420 cm before it collapsed. When the brick ceiling that lay on the rotten boards fell down, under it we found centuries-old wooden beams, and metal I-beams (behind which we later hid the backlight), and mezzanine window, all these elements dictated a lot in the project.
Of course, it brought a lot of trouble, but it was worth it, it allowed to create a mezzanine pantry above the bedroom, and a mezzanine above the bathroom, access to it through the library staircase.
At the end above the library, I managed to make a light window into the bathroom, I think this is the good element in the project. Thanks to the roof, the mezzanine window turned out to be a space flooded with light. Such design decisions and the amount of light (which is unusual for Moscow) reminded me of a Mediterranean house, hence the stylistics.
