Room-by-room outputs Permit packet exports Clear scope assumptions Coordinated trades

Who it’s for

Purpose-built for teams delivering high-performance custom homes.

Architects

Validate loads early and ship client-ready narratives without coordination drift.

Early load validation Client-ready narratives Updated assumptions log

Key outputs

  • Floor-by-floor load summaries
  • Permit packet narratives
  • RFI-ready scope notes

Design workflow

  • Trace plans once, reuse across trades
  • Coordinate assemblies with consultants
  • Share revisions with clear diffs

Builders

Lock material takeoffs and keep rough/trim scopes aligned across trades.

Material takeoffs Trade coordination Revision tracking

Key outputs
