nice :) I suggest to use not-so-contrast texutre, as it produce strong 
morey (mini-waves on wall on right side of picture) or to use stronger AA 
(especialy with much lower threshold, and maybe with jitter)

-- 
#macro g(U,V)(.4*abs(sin(9*sqrt(pow(x-U,2)+pow(y-V,2))))*pow(1-min(1,(sqrt(
pow(x-U,2)+pow(y-V,2))*.3)),2)+.9)#end#macro p(c)#if(c>1)#local l=mod(c,100
);g(2*div(l,10)-8,2*mod(l,10)-8)*p(div(c,100))#else 1#end#end light_source{
y 2}sphere{z*20 9pigment{function{p(26252423)*p(36455644)*p(66656463)}}}//M

setting are aa0.01 +r6. There was a bit of discussion about it, when I 
posted the previous building, and it seems, that I can get better 
results by rendering at 5 times the final resolution, and do some tricks 
with gaussian blur, but that will have to wait for the final images of 
the complete scene.

Not on my screen it doesn't. I always admire this kind of work - so much
time and effort.

beautifully done.

If I recollect right, these are real buildings? If it is so, the ignore this
remark, but otherwise I would like to note that the window above the left
door seems to be placed higher than the other windows which looks odd to me.

try rendering simple checker plane scene, with camera observing the 
horizont and with small checker scale. It is example of almost impossible 
to get rid of alias. 
In this case You can use:
threshold 0.00001 method 2 depth 5..7
or typical AA, but render scene at x5 higher resolution and then down-
sample, but it would in fact be same as threshold 0.00001

pow(x-U,2)+pow(y-V,2))*.3)),2)+.9)#end#macro p(c)#if(c>1)#local l=mod(c,100
);g(2*div(l,10)-8,2*mod(l,10)-8)*p(div(c,100))#else 1#end#end light_source{
y 2}sphere{z*20 9pigment{function{p(26252423)*p(36455644)*p(66656463)}}}//M

I usually blow image at twice resolution and shrink it back both with
interpolation

They are real buildings (if I had designed them myself, there would be 
much more standardization, and not eg 26 different windows), so if you 
are unhappy with the design, you have to take it up with the architect. 
   As the building is from 1904, he may be difficult to reach... :)

Photo attached to prove that it really looks like that.

So I just have to get Rafal to get a screen like yours, and the problem 
is solved :)

Thank you.

I don't think the threshold has much influence, it is method 2 depth 5 
that is equal to rendering at 5x and reducing. If I understand it right, 
threshold only determines whether two neighbouring pixels are different 
enough to need antialiasing. Antialiasing pixels that are almost 
identical can't do much difference in the image IMNSHO.
