The project concept was to separate the house into two (almost equal ) homes sharing the same living, dining and kitchen area with MINIMUM ENERGY WASTE by keeping most of the external and internal walls, the same footprint of the building and most of the openings so no many demolishing and building work to be made for faster function with less effort.
For more internal and external dimensions it is mentioned in the private Floorplan cad source.
I am happy working on your project and looking forward to working on the internal and execution drawings in the future at any time.
