The building will have a warehouse appearance (similar to SAW - The Ride) and contain the main dark ride experience, a pre-show and shop. The plans also include a welcome plaza with themed structures and a covered queue line. The building will be 10m in height, in accordance with the restrictions of the Medium Term Development Plan.
Our edited plan above shows some internal features but details of the ride system and layout remain a closely guarded secret.
