Well, I am not sure about that one (although that is a solution). I
loaded the mirror into Poseray and had the impression that the geometry
was mirrored, but I might be wrong there.

Last test for today.
I brought all the reflections down to similar levels (have to be tweaked
later on of course) and switched the textures in a number of objects.
More tomorrow.

Correct mirror.
There are no caustics reflection and refraction.
Photons and radiosity are compatible?
How to improve contrast?

Use photons.

Yes.
Make sure though that all the windows are using "photons{pass_through}",
and that all surfaces you want to generate caustics are using
"photons{target on reflection on refraction on}".
In the global settings photons block, you'll also need to set
adc_bailout to a very low value. I'm currently using 1/100000 (1e-5).
> How to improve contrast?
The original colors were probably intended to be in sRGB space, so try
replacing all "rgb" with "srgb" (and also all "rgbf" with "srgbf",
"rgbt" with "srgbt", and "rgbft" with "srgbft").
This will reduce the brightness of many materials, thereby reducing the
effect of radiosity. As a consequence, areas in shadow will experience
not only an absolute reduction in brightness, but more importantly also
a reduction in brightness relative to areas in bright light. (As areas
in bright light will also get a bit darker, you may want to increase the
light source's brightness to compensate.)

How to write down?
example:
pigment{ color srgb < 0.5, 1, 0.3, 0.7>}?

Yes, I added. :(
But, It is a lot of big windows, unless it shouldn't be lighter in the room?

Further down the line, UberPOV gives me this.
Which reminds me that I still have to make blurred reflections work
properly with photons.
