Scanning a whole house: room by room, floor by floor

Single-room scans are the demo. Whole-house scans are the job. Here's the workflow we use.

Scan in a loop, not at random

Start at the front door and work through the house the way water would flow: room, hallway, next room. Scanstead merges rooms as you go, and adjacent scans align best when they share a doorway you just walked through.

One room, one scan

Resist the urge to capture two small rooms in one pass. The merge is smarter than that: scan the bathroom, end the scan, scan the closet. Scanstead's whole-house mode stitches them into one model with each room labeled and measured separately — so you get per-room takeoffs and house totals.

Stairs connect floors

When you move between floors, scan the stairway as its own pass. It becomes the vertical link that keeps the second floor aligned above the first. In the finished model you can double-tap any floor to isolate it.

When a room goes wrong

It happens — someone opens a door mid-scan, or a room full of mirrors confuses the geometry. Don't restart the house. Finish the loop, then rescan just that room; the merge replaces it in place.

What you leave with

By the time you're back at the front door:

  • A single 3D model of the house, aligned floor by floor
  • Per-room measurements and house totals
  • A dimensioned floor plan for every level
  • USDZ export ready to share with the office

A 2,000 sq ft house takes about twenty minutes. The tape-measure version of that walkthrough takes two hours and still misses a closet.
