Speed Modeling a Random Cosmetics NewYork Building in Blender

Saw a random building in newyork map street view and decided to make it in blender which i'm sharing it here,
I modeled everything from scratch, you will learn a lot along with me, i have even gone through how i make textures from crazy bump, i have made a lot of mistakes
and corrected it, you will all those, i hope this video will be useful for you, and finally sorry for my very laggy laptop.
