Q for Trucklover, or anyone familiar with walthers modulars

[nachoman]

I want to create a reasonable representation of this building for the structure challenge:




I was considering either DPM or Walthers modular systems, but the DPM seem to cost too much. Or, I was considering scratchbuilding. I am not too familiar with the walthers modular system or how the parts go together, or if creating a structure that resembles this would even be reasonable. I understand the wondow arrangement would be somewhat different, and that I would have to substitute brick for stone. So, for those familiar with the walthers system, what parts/kits would work best to represent this building? I am thinking about a space of 6" by 14" on my layout. Again, I am not looking for an exact replica, but something that captures the feel. That includes - the peaked roof visible from the front, the loading area on the lower level, and the best way of representing the window arrangement.

Thanks,
