Two crews from High Wycombe attended a fire in a single-storey outbuilding.
Firefighters used one hose reel jet, positive pressure ventilation (PPV) and small gear to extinguish the fire.
Crews carried out damping down and cutting away hotspots, successfully protecting surrounding property and preventing re-ignition.
A reinspection was carried out later the same afternoon by a crew from Beaconsfield. Thermal imaging camera checks showed the area had cooled, with no remaining signs of fire spread, and no further reinspection was required.
