Building on the triumph of The Polar Express and the Janssen Pharmaceutical displays in 2021 and 2022, we have amplified the Elf House Christmas set to new heights. These additional pieces are designed to enhance any Christmas scene, bringing it to life with intricate detail and providing visitors with a one-of-a-kind opportunity to interact with the set and snap memorable selfies.

In 2021, we were asked to create a vast outdoor immersive Christmas display scene for Janssen. The theme of the exhibit was a winter wonderland, complete with charming elf houses adorned with colorful baubles, candy canes, and lollipops, reminiscent of a typical elf winter village. Each house was thoughtfully designed to serve as a selfie spot for guests, allowing them to capture memorable photos as well as including an immersive element to the scenes. Additionally, the display boasted numerous Christmas trees that led visitors down a winding path of bark to a snow-dusted scene where they could meet Father Christmas sitting atop an enormous ice sculpture throne, surrounded by snow. The winter wonderland was enclosed by white fences adorned with decorative garlands, and the entire exhibit was illuminated with warm white twinkling lights.

Moreover, we also decked out the entrance to the Janssen building with festive decorations, including giant red and gold baubles festooning the garlands on the front archway. Nearby trees and bushes were also embellished with baubles, and a massive 40ft Christmas tree added to the merriment of the season.

As we continued to work with Janssen, we enhanced the experience by adding animatronics and interactive windows, hence creating a more engaging and memorable experience for all those attending.
