Clear pictures - help requiered

I don't see any problem with the sharpness.  If you zoom into the left hand side of the building everything is sharp.  I'm assuming Sharpening has already been applied if the OP processed the Raws in DPP and used the default Picture Style settings like Standard or Landscape.

The trees on the left of the building do look a bit soft and I suspect that might be due to the +2 Luminance Noise Reduction that is applied by default to Raws in DPP.  In the preferences I set all the NR sliders to 0 so that I can see unadulterated sharpness from the camera.  It makes quite a difference to fine detail.
