Latin baroque building

The special thing about this building is the system of tiling wall texture. I remember that the requirements for that particular building were that:

1. all the brown gap should be kept as they were in concept art;


2. not be modeled but made only by texture; everything should be made with the fewest and the smallest possible textures.
   
   

I had a wall of about 10, 70 meters and with the technique of advanced tiling I managed to cover it with only 8 meters (1024 pixels) and keeep the rule of 128 texture pixels /1 meter of geometry.

So instead of having 5 textures for this building I reduced them to 4.
1. this-the wall texture (1024/1024),

2. the building parts texture (1024/1024),

3. here is the third roof paviment (512/512),

4. and the alpha one (256/256),

Of corse, with normal and specular map:
