Low Poly House Challenge

This is the start of a Low poly house Model. I had started to make the shape of the house and then add details after. Furthermore, I ahd trouble to make it look more realistic and made it look plain and basic. However the next day I restarted and started again creating this - 

This modem has higher amounts of detail but the main part of the house has not been created. Secondly, I added small touches to make it look like the original photo.
