3d Interior/Exterior Sketchup Model from 2d .dwg files

Design details: Hi, I want to get a 3d sketchup model done up showing interior and exterior from existing 2d autocad drawings for a 2 storey dwelling. I also can provide elevations from an existing exterior only 3d sketchup model. The purpose of the model is to examine options for the orientation of the building on site in order to maximise the amount of natural light in the interior so a very high level of texturing/detail is not required.
Ideas for the visual style: Similar to sketchup photo attached
