The next generation of virtual tours
Experience places anew.
Your guests, tenants and buyers move freely through your spaces, step by step and in every direction. Photorealistic, right in the browser, on any device.
Step inside.
From the map across a 3D model of Frankfurt up to the 29th floor. Start walking, right in the browser.
Step insideCOLLECTION Business Center
Every location on one map. Choose Frankfurt, and a flight across the 3D city model takes you into the tower, right onto the right floor. From there, you move freely through every area. In each one, a button leads to booking or inquiry, and every room has its own link.
Like being there. From anywhere.
A Leichner3D tour is a space you step into. You decide where to go and what to look at.
Move freely
Every room, every angle, at your own pace. Mouse and keyboard on desktop, touch on your phone.
Photorealistic
Light, materials and depth look real, because every tour is built from a scan of the actual place.
Automatic pathfinding
One click on the floor is all it takes. The tour walks you there on its own, around furniture and corners.
Room views in 8K
At defined viewpoints, a razor-sharp panorama opens up for you to look around.
Virtual staging with AI
The same room, refurnished by AI: one switch in the tour, clearly labeled as a visualization.
One link, any device
No app needed on phone, tablet or desktop. Automatically in German or English, in your branding.
From picture to space.
Inside and out.
Where the site allows, we scan the building from the outside as well. In exterior mode, you circle it and take in architecture, garden and setting at a glance. One click, and you're back inside.

We develop what you see.
Leichner3D is a technology company based in Mannheim, Germany. The software behind our tours, from processing the scans to the viewer your visitors walk in, is developed in-house.
That lets us decide what a tour can do and shape every tour around your place and your goals: custom features, your content, your branding down to the last detail.
Our own viewer
Built for walkable, photorealistic spaces. Every feature in it is ours.
Features made to measure
Whatever your tour needs to do, we build it ourselves, directly in our own software.
Short paths
You talk to the team that writes the code. Your feedback goes straight into the software.
For places that need to impress.
Wherever the first impression decides a booking, a lease or a sale.
Hotels and resorts
Guests walk through suite, spa and lobby before they book.
Offices and business centers
Prospects tour spaces and meeting rooms without traveling.
Real estate
Buyers and tenants know every room before the first viewing.
Event venues
Planners design their event inside the tour before booking the venue.
Showrooms
Customers explore your showroom around the clock.

No. The tour runs directly in the browser on phones, tablets and desktops. A link is all it takes.
For as long as you want to use it. We run it on our own infrastructure and keep it technically up to date.
We capture your spaces one by one. Nobody should move through the scan area during capture. How long it takes depends on the size of the space, and we agree on the date with you in advance.
We process the recordings on our own systems and host your tour GDPR compliant on servers in the EU. People, license plates and anything confidential are made unrecognizable.
