I’m skeptical that abandoned malls can be converted into fulfillment centers; 1. Not enough loading docks 2. Ceiling height not right 3. Big efficiency gains from custom build plans 4. New warehouse construction is cheap 5. Amazon tore down this mall to build a FC from scratch https://twitter.com/JasonSzegedi/status/1211268042962980865 …
Imho, check the other reply. If you’re going to do that much work, you’re probably better demolishing. I think the best repurpose is storage facilities.
