Garage falling down, potential damage to gas line and electrics, not covered by home insurance?

Challenge the insurance company’s denial of coverage. Argue that the policy should cover latent defects and pre-existing issues that were not disclosed or evident at the time of purchase.

Suggest that the insurance company’s refusal to cover this claim is unreasonable given the potential for severe damage and risk to life.

Can the insurance company prove that this is not sudden movement and is down to bad workmanship?

What would be the basis for this argument? Normal buildings insurance simply does not cover this as a risk. "Sudden movement" isn't in itself an insured risk either. And "potential for severe damage and risk to life" doesn't turn something into an insured risk.
