How Brands Can Make a Lasting Impact: Outernet x GOSH Charity’s Big Build Adventure
This August, Outernet has partnered with Great Ormond Street Hospital Charity (GOSH Charity) to launch one of our most ambitious and meaningful experiences yet – The Big Build Adventure. The campaign marks a powerful moment in the development of the new Children’s Cancer Centre at Great Ormond Street Hospital (GOSH) and shows just how deeply immersive media can connect with the public in real-world, real-time ways.
As the UK’s most visited cultural attraction, now welcoming over 80 million visitors annually, Outernet is uniquely positioned to drive engagement, emotion, and action at scale. This collaboration with GOSH Charity is a prime example of how brands and organisations can use our platform not only to tell their stories, but to build movements.

Immersive Storytelling with Purpose
Running from August 6th to 31st, the experience transforms Outernet’s screens into an interactive construction site brought to life by motion-tracking technology, animation, and gamified design.
At the heart of the activation is a giant virtual Paint Workshop wall, where visitors use motion gestures to “paint” the walls of the new Children's Cancer Centre, illustrated by artist David Vallade. This participatory canvas invites audiences to become active contributors to the campaign – a powerful model for brand engagement in public space.
Further digital touch-points include:
Interactive Games via a QR code-triggered app, themed around construction, from matching tools in a digital toolbox to spotting building differences in real-time.
Augmented Selfie Moments where visitors can become ‘Employee of the Day’ and be featured on the big screen.
Fundraising Integration with opportunities to "buy a brick" and directly contribute to GOSH Charity’s mission.
Why This Matters for Advertisers
Outernet’s collaboration with the GOSH Charity demonstrates the strength of purpose-led campaigns in today’s advertising landscape. It reflects three key principles that increasingly matter to audiences and advertisers alike:
Interactivity – Immersive media moves beyond storytelling to story-doing. When audiences can engage, create, and share, their connection deepens.
Social Impact – Brands today are expected to show up with more than just a product. Associating with causes that matter builds long-term equity.
Unmissable Visibility – Outernet offers one of the most visually commanding canvases in the world. For GOSH, this means mass reach. For advertisers, it means unparalleled cut-through in a high-footfall, high-attention space.
More Than Media – It's Movement-Building
The Children’s Cancer Centre at GOSH will be a world-class facility combining treatment, learning, and play. It’s a project that brings together hope, innovation, and human impact – values that resonate with our own mission at Outernet.
Jessica Dracup-Holland, Chief Marketing Officer at Outernet, summed it up perfectly:
“This experience reflects everything Outernet stands for – innovation, creativity, and impact – and we hope it captures the imagination of every visitor while helping to make a real difference for the children and families who need it most.”
Book With Purpose:
For brands, agencies, and advertisers looking to create campaigns that don’t just appear in a space but live in it – Outernet offers a one-of-a-kind environment. Whether you’re building awareness, activating a community, or launching something new, the possibilities are limited only by imagination.
This summer, the GOSH Big Build Adventure shows just how powerful that imagination can be when paired with purpose.
