Phantom Peak is one of the most ambitious immersive worlds ever built in London — a full Western-steampunk town complete with lakes, canals, bars, restaurants, interactive game trails and multi-room environments.

Tandem designed, fabricated, scenic-finished and installed the entire experience — transforming an abandoned car park into a living, breathing world.
