BRING_DOWN_THE_RING has previously posted a theory, that the #killroom is actually a shipping container: https://voat.co/v/pizzagate/1455487

I've recently found that Care 2 Communities https://archive.is/8PiGg was formerly Containers 2 Clinics. https://archive.is/v76V4 :

"Containers 2 Clinics (C2C) seeks to reduce maternal and child morbidity and mortality rates in the developing world by providing access to high-quality primary healthcare for women and children. We deploy shipping containers converted into clinics to areas with inadequate facilities and collaborate with local organizations and governments to provide clinical, laboratory, pharmacy, and health education services."

Alefantis managed Johnny's Half Shell https://archive.is/hu5jg#selection-1175.88-1175.348 and it is linked to a maternal / child organization, that operates in Haiti and deals with shipping containers. https://archive.is/OzwA6is

This place here https://archive.fo/QhX3I or http://www.gatewaycontainersales.com.au/shipping-containers-a-medical-clinic-in-a-box/ provides containers of all kinds designs. It's very possible, looking at it from this perspective, that the killroom could be a shipping container.
