Kettering Borough Council wants to turn the town's crematorium into a venue for marriages.
Bosses say the idea has come after members of the public have asked about getting married there.
The council says the two types of service would never be held on the same day.
The crematorium signs would need to be removed say the council and the room layout would also be altered with the area where coffins go for cremation being cordoned off. There would be a name change as well, which has yet to be decided.
