Tercüme - Türkçe-İngilizce - Mekanin Cennet olsun dedecigim

There are two possible interpretations here - it could mean that this person hopes that the new home that his/her grandfather has moved into or built will be heavenly, but it could also mean that the grandfather has died, and s/he hopes that he's going to heaven! I've tried to make the English ambiguous, too.
