Dear client, you'll find full description of the apartment's room distribution and purposes in the floorplans layouts, page 3. I've used the walls on the dwg file as nonchangable and build everything around them with new ones to shape the rooms and spaces. Most of the mezzanines are over service rooms like corridors and bathrooms which is a smart way to use the height of them without taking away the comfort. I enjoyed working on your project with the specifics you gave and I hope my preposition meets your criteria! Good luck with the realization!
