İ had a question regarding offering prayers at my ancestral house. İ have a stay of 4 days here. İ wanted to ask if İ would be offering Qasr prayers or full ones. It is my grandfather's house and we pay a visit there at least once a year but do not live there permanently so I was asking in this case whether when I go there, I should pray Qasr or full prayers. Please guide.

If you did not live there and it wasn’t your home before then you must pray Qasr.
