Dodgy wiring, damp walls, demonic wailing … there’s a lot to look out for when buying an old mansion. Zillow tasked us to trick or treat home-seekers in times when open houses weren’t possible. In 17 days—just in time for Halloween—we created a virtual haunted house, lurking among the real listings. Daring visitors explored Thistle Mansion through an interactive tour that bridged filmmaking with 3D tech. Leading up to the launch, video teasers captured the curiosity of Zillow’s 3.5 million social followers—driving interest in Zillow 3D Home Tours and making virtual viewings a supernatural success.
