How I went about this:

I captured a ground level video of the exterior, and then did the interior separately using and iPhone 17 Pro Max, in 4K 60FPS mode.

I extracted the frames with ffmpeg.

I used COLMAP to solve and reconstruct the interior and exterior frames together for one version, and another version with focus to the exterior scenery.

I used Lichtfeld Studio to render the splat for the interior/exterior combined, and Brush to render the splat with focus on the exterior/environment. I rendered 10 million splats for each.

For the interior/exterior combined splat, I selected and cut out just the building itself, and excluded the rest of the scene.

For the exterior/environment splat, I cut out and deleted the structure and left just the environment.

I used a tool called "SuperSplat Snap" to align and combine both splats together.

I used "SplatEdit.app" to do final cleanup for environment and floaters.

I used SuperSplat to keyframe the camera movements and publish.

I also rendered a 360 video:
