Sussex Fire Chief Harold Lowe tells Tide News smoke was seen coming from the building after staff had left the office and when crews arrived the roof was fully engulfed in flames and starting to collapse. While the structure itself is still standing, the roof is gone and the D-N-R office has sustained some water damage.
One firefighter was taken to hospital as a precautionary measure with possible heat exhaustion.
The fire marshal will be coming to investigate what caused the blaze.
