HouseTwin
Turn ordinary phone and drone photos of a property into an interactive, browser-viewable 3D model — no survey scanner, no LiDAR rig. The same reconstruction core behind ASI Labs spatial twins, shown as an honest early preview.
What it is
HouseTwin reconstructs a property in 3D from ordinary RGB photos or video using a classical photogrammetry pipeline (feature matching + structure-from-motion) trained into a 3D Gaussian splat, then serves it as an interactive precomputed scene that runs in a browser with no app install. A companion iOS app captures synchronized RGB + LiDAR-depth frames with per-frame pose.
The demo is a residential exterior walked with a phone: 313 video frames solved into a single camera model and trained into a Gaussian splat, then cleaned and cropped to ~849,000 Gaussians that render live in the browser. Two further subjects — a plant and a vehicle — were captured and reconstructed on the phone itself, using its camera and LiDAR together.
Where it fits
Capturing and viewing a splat in a browser is now commoditized (Polycam, Scaniverse, the free SuperSplat viewer), so that layer isn't the value. The genuine whitespace is a unified exterior + interior property twin with 3D-consistent renovation editing and cost/ROI decision support for solo agents, FSBO sellers, and renovators — a direction the reports lay out but that is roadmap, not built. Today, HouseTwin is a capability showcase: flexible capture from cameras you already own, and an honest 3D preview.
Try it
Orbit a real reconstruction in your browser.
A garden and house front solved from phone video alone — no depth sensor used — plus a plant and a vehicle reconstructed on the phone itself with camera and LiDAR together — orbit, zoom, and pan, rendered live in WebGL2. Precomputed offline; no reconstruction runs in the browser. Further captures are shown as stills until they are ready to publish.
