Answer
(Fatwa: 1710/1180/L=1432)
It is makrooh to offer salah in such a place where there are pictures above, front, right or left side.
و أن يكون فوق رأسه أو بين يديد أو بحذائه يمنة أو يسرة أو محل سجود تمثال (درمختار مع شامي: 2/416-417)
Hence if some other place is available instead of that office where you can offer salah, you should offer salah therein. However your salah shall be alright if you offered salah in that room out of compulsion.
