Deciding whether to restore your building or tear it down and start again can be difficult. You should always consult with a restoration expert first to understand what it will take to restore your building to its pre-disaster state. Then you can compare that to reconstruction in terms of safety, cost, convenience, and legal restrictions.
Your insurance company may recommend one course or the other. Sometimes your coverage will make that the most desirable option, but other times coverage is too small to sway your choice.
