How a possible renovation of my own personal home could look like

Im an 17 y/o hopefully quickly to be arch scholar and out of boredom i opened up sketchup and created an idea of how my present private residence might appear like if renovated. The gable roof construction is the unique a part of the constructing whereas every thing else is an addition. For the outside i primarily used wooden planks and in addition put greenery on the flat roof. The constructing is nearly completely oriented north/south. Let me know what you assume!
