The answer almost certainly lies in your source photos, but from a quick google i can see that this building is very smooth, plain and shiny, and that is not a good thing for photoscan :(

Try pre-processing the images in a software such as lightroom in order to reduce the highlights / whites so that your pictures are more neutral and suffer less from the shiny white texture.

I've had same Problem at the glass building. I suggest, before taking the pics you should reduce the lightness of the camera. maybe you can shoot if in the outside cloudy. But all this is only my opinion. I hope you solve the problem.
Please write the short infos about your solution.
