Unwrap UVW

After creating a basic box house model, we were asked to "unwrap" the model we created, first I selected on the modifier list and chose the Unwrap UVW option.

I then selected different sections of my house to unwrap, here is my finised net after unwrapping the house model.

I resized the map to fit in the outlined grid, I then print screened the net and pasted it in photoshop and cropped the grid with the net inside. I now can now use the map as a guideline as to where to use my texture for the walls and roof, here is a quick texture:

I saved the texture as a .jpeg and am now able to use it as a texture for my house, here is the house with the added texture:
