In this video tutorial I explain how to create the main building walls with simple and speed way.
Probably existing other systems to achieve the same result, but this technique, for me, through the experience I made in the architectural 3D visualization field with Blender, is the best.
Using this modeling type in fact, is possible simply apply the loop cuts for wall openings and the material textures.
