Ambulances as well as fire engines will soon be dispatched from Callington Fire Station.
An agreement has been signed between Cornwall Fire and Rescue Service (CFRS) and South West Ambulance Service (SWAST) paving the way for the two emergency services to be based in one station.
Lance Kennedy, Cornwall Council portfolio holder for community safety and public protection, said it was good news all round.
"This is a fantastic partnership and one which will have a positive impact on the local community."
With the nearest ambulance stations at Liskeard and Saltash, ambulance bosses had been looking for a permanent base for crews covering the Callington area.
They then decided to approach the fire service about sharing its facilities.
Recognising the benefits to the local community, Paul Walker, deputy chief fire officer, said they were happy to help.
"Joint working in this way improves the service we provide by linking resources to risk and delivers efficiencies whilst maintaining and improving frontline services," he said.
"I am delighted we are further enhancing our established partnership with South West Ambulance Service.
"This partnership really supports our service mission of working together to make Cornwall safer and provides an opportunity for shared training and effective use of community facilities."
Steve Boucher, SWAST head of operations for Devon, Cornwall and the Isles of Scilly, welcomed the partnership.
"We are delighted that our collaboration with Cornwall Fire and Rescue Service continues."
