3D Virtual Tours & Interactive Walkthroughs
We transform architecture and real-world spaces into immersive, interactive 3D experiences for web and VR.
BEYOND THE STATIC IMAGE
Don’t just show a space. Let people experience it.
A great virtual tour is not a camera moving through a 3D scene. It is a clear and enjoyable way for visitors to explore a place, find what matters to them and understand spatial relationships. Fourthedesign combines real-time 3D production with interaction design to create that experience.
For a future development, this might mean navigating from a masterplan into a property. For an existing heritage site, it could mean exploring a photorealistic reconstruction in VR.
OUR CAPABILITIES
Built around the way people explore.
Different objectives need different production methods. We design the experience around the place, its audience and the devices that will be used.
01 / WEB 3D
Interactive 3D Environments
Browser-based walkthroughs with custom navigation, selectable locations and contextual information. Especially useful for developments, buildings and presentation platforms.
02 / VIRTUAL REALITY
Immersive VR Walkthroughs
An engaging sense of scale for architectural projects, cultural heritage, exhibitions and guided experiences, developed and optimized for the agreed VR hardware.
03 / REALITY CAPTURE
Photorealistic Reconstructions
Image-based environments created from suitable photographs and drone footage. Gaussian Splatting can bring complex real sites into an interactive visual scene.
SELECTED WORK
Proof through real projects.
Three very different experiences. One approach: choose the technology that makes each space understandable and useful.
01—03
PROJECT 01 / WEB 3D & REAL ESTATE
ENIGMA
An interactive Web 3D real-estate explorer that connects spatial navigation with property information. Visitors move around a development rather than relying on a fixed video or separate lists of images.

PROJECT 02 / ARCHITECTURAL VR
Kourtidis Group
A standalone Meta Quest 3 property presentation that brings future neighborhoods, developments and interior spaces into an immersive sales experience. Buyers can understand the scale and atmosphere of places before construction.

PROJECT 03 / REALITY CAPTURE & CULTURE
Historic Monasteries of Crete
Drone imagery of Apezanon, Odigitria, Varsamonero and Vrontisi was used to reconstruct four photorealistic Gaussian Splatting scenes. Fourthedesign integrated the result into a Unity VR experience for cultural heritage exploration.

FROM IDEA TO EXPERIENCE
A clear process. A better result.
01
Discover
We review your audience, existing files, locations, desired interactions and target devices.
02
Create
We produce or prepare the right geometry, models or captured scenes and design the visitor journey.
03
Develop
Navigation, selection, media and interactions come together in a responsive real-time application.
04
Deliver
We test on the intended platforms and agree on deployment, maintenance and future updates.
COMMON QUESTIONS
What should you know before starting?
For more technical detail, read our guide to choosing a 3D virtual tour company in Greece or explore Digital Twins & Interactive 3D.
Is a 360° photo tour the same as interactive 3D?
No. Panorama-based photography and custom real-time 3D are different methods. The appropriate choice depends on whether the goal is photographic viewing or a more flexible interactive environment.
Do visitors need a VR headset?
No for a browser-based Web 3D tour. VR is an optional immersive platform that requires a compatible headset and a suitable implementation.
Can we start with CAD or BIM files?
Yes. Existing architectural files, 3D assets, photographs and appropriate drone imagery can help shape the production workflow, subject to their quality and permissions.
Is Gaussian Splatting suitable for technical measurements?
Not automatically. A visually realistic scene is not necessarily a verified survey or editable BIM model. Technical accuracy needs its own capture and validation requirements.
