Strontian Primary in Strontian in the north west Highlands was built in the mid-1970s and takes pupils from the Ardnamurchan and Morvern peninsulas.
Councillors will be asked a meeting next week to agree that the school be accommodated in new units at the village's Ardnamurchan High School.
The proposal would cost about Â£1.16m, council officers have said.
The 1970s building forms part of a wider complex, that includes the village hall.
Council officers said the local authority would work with the community to explore the future use and ownership of the hall.
Highland Council has set out plans to replace one of Scotland's most remote schools.
