A new doctors’ surgery will be built in Smallway, Congresbury, replacing the Yatton and Congresbury facilities.
North Somerset planners approved amended plans this week having previously turned down the application despite council officers recommending approval.
The new surgery will be on land opposite Cadbury Garden Centre.
The original plans had been refused because of concerns over access, particularly pedestrian access.
Councillors approved the plans, noting that if it went to appeal, they would lose.
