An AR walkthrough in real estate lets a buyer walk through a full-scale, decorated apartment rendered in augmented reality on a tablet, phone, or Apple Vision Pro. The buyer does it while standing on the bare concrete floor of a construction site, before the walls exist. It differs from a 360 tour or a 3D scan in one structural way: capture-based tours need a finished space to photograph, so they cannot exist for a building that has not been built. R2U, a Brazilian proptech company specializing in immersive sales experiences for real estate developers, renders the walkthrough from architectural plans instead. That turns every unit into a model unit on site. Properties marketed with 3D tours sell 31% faster than those without (Matterport, 2019, 143K-property study), and an on-site AR walkthrough pushes that confidence to the moment a buyer is physically in the building.
What Is an AR Walkthrough in Real Estate?
An AR walkthrough is a life-size 3D model of an apartment, anchored to a real physical space, that a buyer moves through on foot using a phone, tablet, or Apple Vision Pro. The decorated rooms appear over the actual construction floor at real scale, so the buyer sees room dimensions, ceiling height, and finishes the way they will exist after handover.
The word “walkthrough” matters here. A static render is one fixed image. A 360 tour is a set of panoramic viewpoints you click between. An AR walkthrough has no fixed viewpoints at all. You walk, and the model tracks your movement through the space, room by room.
R2U builds these walkthroughs as part of its AR staging product, the full-scale, decorated apartment buyers explore on the construction site. The same architectural assets also power the browser-based 3D sales platform, so a developer pays once for the 3D production and uses it across the funnel. A sales agent can run the AR walkthrough on a tablet during a site visit, then share a link so the buyer keeps exploring from home.
The on-site version is the one buyers remember. Standing on a raw slab on the 14th floor and seeing a finished living room appear at full size, with the real view through where the window will be, does something a brochure cannot.
AR Walkthrough vs 3D Walkthrough vs 360 Tour
The three formats sound similar and do different jobs. The table below lays out where each one fits.
| Format | What it is | Where the buyer is | Needs a built space? |
|---|---|---|---|
| 360 tour | Linked panoramic photos or renders, click between viewpoints | At a desk or on a phone | Photos need a finished room; renders do not |
| 3D walkthrough | Navigable 3D model viewed on a screen, free movement | At a desk or on a phone | No, can be rendered from plans |
| AR walkthrough | Full-scale 3D model anchored to a real space, walked on foot | On site, in the physical building | No, rendered from plans and placed on the slab |
A 360 tour built from photos is the most common format, and it carries a hard limit: you need a finished room to photograph. Scan-based tours, including the LiDAR and photogrammetry capture that drives most virtual-tour software, have the same dependency. None of them can show an apartment that is still a concrete shell.
The 3D walkthrough solves the “unbuilt” problem on a screen. R2U renders it from architectural plans and serves it in the browser, no app and no download, so a buyer compares units from a laptop. The AR walkthrough takes that same model and places it at real scale in the actual building, which is the part a screen cannot reproduce: the body’s sense of how big a room is.

How an AR Walkthrough Works on Phone, Tablet, and Apple Vision Pro
The walkthrough runs on three device tiers, and the buyer needs no special hardware for the first two. On a phone or tablet, R2U delivers the experience through WebAR, which runs in the browser from a QR code or a link. No app to install, no app-store friction during a sales meeting.
On a phone or tablet, the device camera reads the floor, the software anchors the apartment model to that surface, and the buyer walks around holding the screen like a window into the finished unit. This is the workhorse format for a busy sales gallery, because any broker can hand a buyer a tablet and start the tour in seconds. Our WebAR real estate guide covers the no-app distribution model in detail.
Apple Vision Pro is the premium tier, and R2U is the only company in Brazil with Apple Vision Pro for real estate. R2U has delivered 8+ projects for developers including Tegra, a Brookfield subsidiary and one of Brazil’s largest builders, and MPD. With the Apple Vision Pro headset, the apartment renders at full scale around the buyer in spatial computing, hands free, with gesture control to swap finishes or change the time of day. Apple shipped an updated Apple Vision Pro with the M5 chip in October 2025, which renders larger, higher-fidelity developments without dropping frames.
Across all three tiers, the buyer can change floors, materials, and lighting in real time. The experience is the same model rendered from the same plans, scaled to the device.
Why Capture-Based Tools Can’t Do Pre-Construction
Capture-based tools photograph or scan an existing space, which is exactly why they fail for new construction: there is nothing to scan until the building is finished. By the time a 3D scan is possible, the developer has usually already sold most of the inventory, when buyer confidence mattered most.
This is the structural reason AR walkthroughs matter for pre-sales. In pre-construction, most of a development’s units are sold before completion, during the period when the apartment exists only on paper. A scan cannot help there. A render from architectural plans can.
R2U builds every walkthrough from the developer’s plans and finish specifications, not from a camera. The model exists the day the plans are approved, long before the foundation is poured. That is what lets a sales team run an AR walkthrough on the bare slab during the launch phase, when the building is a skeleton and the buyer needs the most reassurance.
The same approach feeds the browser 3D sales platform and the on-site AR staging experience from one production pass. No scanning, no waiting for a finished show home, no demolished model unit at handover.
The Sales-Floor Workflow and Remote Follow-Up
The AR walkthrough fits a two-step sales motion: a high-impact on-site moment, then a low-friction remote follow-up. On site, the agent loads the walkthrough on a tablet or Apple Vision Pro and walks the buyer through the actual unit in the actual building, at real scale. This is the version that closes.
After the visit, the agent shares a browser link, and the buyer keeps exploring the 3D version from home, on a phone or laptop. R2U’s platform records how buyers behave inside the experience, which units they compare, which finishes they linger on, so the sales team follows up with specifics instead of a generic check-in. That behavioral data is a differentiator most capture-based tours do not offer.
The economics favor this model. A physical model unit, the decorated apartment in the sales gallery, runs from roughly $90,000 to over $360,000 for a luxury development and gets demolished at handover. An AR walkthrough turns every unit into a model unit, on every floor, from around $5,400 for an Apple Vision Pro experience. The developer stops betting the whole marketing budget on one decorated apartment.
Timeline and What Developers Provide
An AR walkthrough takes 3 to 14 weeks to produce, depending on the device tier and the complexity of the development. A browser-based 3D walkthrough and AR staging run 3 to 10 weeks; an Apple Vision Pro experience runs 4 to 14 weeks. By comparison, a physical scale model takes 2 to 5 months and cannot be updated once built.
To start, the developer provides architectural plans, finish specifications, and any existing renders. R2U handles the 3D production, the AR anchoring, and the device delivery. Because everything is rendered, late design changes, a swapped countertop, a revised facade, update in the model without a reshoot or a rebuild.
Developers who want the on-site experience plus the browser follow-up should plan for the full pipeline up front, so the same assets serve the sales gallery, the WhatsApp link, and the Apple Vision Pro headset. To see an AR walkthrough built from your own plans, book a demo.
FAQ
What is an AR walkthrough in real estate?
An AR walkthrough is a full-scale, decorated 3D apartment rendered in augmented reality and anchored to a real physical space, which a buyer walks through on foot using a phone, tablet, or Apple Vision Pro. R2U renders it from architectural plans, so buyers can walk an unbuilt apartment on the bare construction floor before the walls exist.
Can you do an AR walkthrough of an apartment that is not built yet?
Yes. Because R2U renders the walkthrough from architectural plans rather than scanning a finished room, the model exists before the foundation is poured. The buyer stands on the raw construction floor and sees the finished apartment at full scale, which capture-based tools cannot do because they need a built space to photograph.
What is the difference between an AR walkthrough and a 360 tour?
A 360 tour is a set of fixed panoramic viewpoints you click between, usually built from photos of a finished room. An AR walkthrough has no fixed viewpoints: the buyer walks through a full-scale 3D model anchored to a real space and tracked to their movement. The AR walkthrough also works for unbuilt apartments, which photo-based 360 tours cannot.
Do buyers need to download an app for an AR walkthrough?
Not for the phone and tablet versions. R2U delivers the on-site walkthrough through WebAR, which runs in the browser from a QR code or a link, with no app and no download. The Apple Vision Pro version uses a dedicated app on the headset for the premium, hands-free experience.
How much does an AR walkthrough cost?
R2U’s Apple Vision Pro experiences start at around $5,400, and the browser-based 3D sales platform starts at around $2,700. For context, a physical model unit costs $90,000 to over $360,000 for a luxury development and is demolished at handover, while an AR walkthrough turns every unit into a model unit. Pricing varies by project.
How long does it take to build an AR walkthrough?
A browser-based 3D walkthrough and AR staging take 3 to 10 weeks, and an Apple Vision Pro experience takes 4 to 14 weeks, depending on the development’s complexity. The developer provides architectural plans and finish specifications, and R2U handles the 3D production, AR anchoring, and device delivery.
