Building redrawing/redesign

Hello Serviceprovider. I have a drawing from a single house which have to be redone to adapt it to another location. At the moment the entrance is on the basement and is directed downhill. In the new house the entrance have to be in the first floor and has to be directed uphill. We can discuss thinks upfront of the project. Please se also the attached files. You get also the map of the terrain and you have to make 3 different visualizations pics from the house. We need 3d files (DWG/DXF).
