How long does a LiDAR scan of a home take?

A site visit and scan usually takes about half a day for a single-family home, with a full existing conditions model ready within a week.

Does reality capture make the permit set more accurate?

Yes. Because the drawings come from a scan instead of field measurements and estimates, they are more precise and less likely to require revisions during municipal review.

Can homeowners see their proposed addition before construction starts?

Yes. PUR4 overlays the proposed design directly onto the scan of the existing home, so homeowners see their actual rooms with the proposed changes applied in accurate proportion.

Renovations start with an existing building, and existing buildings rarely match old drawings perfectly. Reality capture gives the design team a more accurate starting point before decisions, pricing, and construction begin.

Renovation projects can run into budget and schedule issues when existing conditions are incomplete, outdated, or assumed instead of verified.

PUR4 uses 3D scanning and reality capture to document existing spaces, identify constraints, create better base models, and reduce coordination surprises during design and construction.

Explains PUR4's reality capture workflow and shows homeowners how 3D scanning can reduce renovation risk, coordination issues, and budget surprises.

Accurate existing conditions are one of the highest-leverage investments a renovation team can make before design decisions harden.

Reality capture does not remove every unknown from a renovation, but it gives homeowners and project teams a clearer, more reliable foundation for better decisions.
