iVR Nation

iVR Nation was a London-based virtual reality and real-time 3D visualization studio founded in early 2015 by designer and architectural visualizer Olivier Demangel. Its work applied video game engine technology to architecture, property marketing and industrial design, creating interactive environments that users could explore before a building or product existed physically.

The studio used Unreal Engine 4 to develop architectural walkthroughs with interactive lighting, weather and material customization. Its development work covered desktop and room-scale virtual reality, mobile applications and 360-degree walkthroughs, with experiences designed for Oculus Rift, HTC Vive, Samsung Gear VR and iOS devices. Alongside production, it offered custom application development, rapid prototypes and digital innovation strategy for architectural practices, developers and hospitality businesses.

Architectural experiences

Its best-known early showcase was the Ty Hedfan VR Walkthrough, presented in April 2015. The project recreated a Welsh house designed by Featherstone Young as an explorable virtual environment for the Oculus Rift DK2. Visitors could move through the residence, open doors, switch lights and change wall and floor finishes in real time. The demonstration attracted coverage in architectural and technology publications and illustrated how interactive visualization could support design communication.

In 2017, the studio collaborated with CRC Companies on a virtual experience for Ten at Clarendon, a 143-unit residential development in Arlington, Virginia. Prospective tenants used HTC Vive headsets to explore interactive apartment walkthroughs during pre-leasing. The studio also released iVR HOUSE, an iPhone and iPad application for viewing mobile architectural and 360-degree walkthroughs.

Its wider portfolio included transport concepts, surveillance aircraft visualization, office interiors and public demonstrations of room-scale environments. These projects extended its architectural visualization approach into industrial design, simulation and exhibitions.

Following a gradual wind-down after 2017–2018, the company applied for voluntary strike-off in October 2019 and was formally dissolved on 14 January 2020.
