Sketchup model

Because I am not familiar with the topography tool on Sketchup, I only did a digital model for the Plains house which has flat terrain.

The walls would be made of brick or earth with styrofoam insulation. If the walls are of earth, extra support around the windows is needed so I showed masonry around the doors and windows as well as on the corners of the house for reinforcement. The roof tiles would be the local clay tiling that is native to Nepal.
