CATCH A DESIGN PROBLEM ON AN EMPTY LOT, IT'S FREE. CATCH IT AFTER FRAMING, IT'S A CHANGE ORDER.
This is a phone camera on an empty yard, AR-mapping the actual house frame onto real ground, full scale, before anything gets built.
WITHOUT AR WALKTHROUGH:
Design issue caught during or after framing.
Cost impact: 5-40% of project budget, per construction cost-overrun research. On a $450,000 build, even the low end of that range is $22,500 in avoidable overruns.
WITH AR WALKTHROUGH:
Design issue caught on the empty lot.
Cost impact: a five-minute walk and an edit to the plan, before anything's actually built.
That gap is the entire pitch. Not a fancier rendering, a cheaper mistake.
This clip shows a house before it exists. The article below covers the flip side, scanning a space that already exists and turning it into something anyone can walk through from a phone, no headset needed.
