Balloon pilot reported a loss of control during landing when the balloon encountered a gust of wind. The pilot deflated the balloon to prevent any passenger injuries; or structural damage to the balloon.

Narrative

I conducted an uneventful flight in a hot air balloon with 15 passengers onboard. I took off at XA:05 and flew for approximately 50 minutes. I landed in a field with less than 3 MPH of forward travel going north. I had received prior permission to land in that field. After a calm landing; while I was waiting for the ground crew; a gust of wind hit the balloon while it was still inflated. I would estimate the wind was 270 [degrees] at 20 [kts]. The gust lasted for about 5 minutes and dissipated back to calm conditions. While the balloon was being hit by the wind; the basket slid about 40 ft. sideways until it was stopped by a berm. When the sliding stopped; the basket on the upwind side started to tip up. I chose to deflate the balloon over a metal structure instead of risk letting the basket tip over; and potentially hurting my passengers. We were able to remove the fabric from the structure with land owner permission and no damage to the structure. There were some tears in the fabric; but nothing structural was damaged. The morning of the flight; the skies were reported by neighboring airports as clear. I saw cloud cover before I took off; but didn't suspect any convection or precipitation that morning. During flight; I saw virga on the horizon; but when I checked foreflight; it wasn't depicted on the radar.
