Brick size is no problem, a matter of changing a number in the material room.  Proportions of the bricks may be a different matter, the texture generated in PovRay, and I think the proportions may be the standard for another country.  I may be able to change the mortar width and thickness, before I give up, I'll give it a try.

Povray gives control over almost everything, all I have to do is figure out the ratio and plug that in, it can make anything from bathroom tiles to cinder blocks, or even ancient stone blocks.  Pretty math intensive and I don't have a lot of math.

It's not that small though, the foundation is 26 by 16 feet, about the same width as my house.  Just not very deep, the main room is 16 by ten (?) I think.  Outside dimensions given.  And I'm still working on the "I don't like this". 

Doric.

The "I" in Doric is Silent.
