Early feasibility depends on the site, but the site data is scattered. Parcel boundaries, slope, planning overlays, and hazard layers each live in a different place and a different format. Pulling them together by hand is slow, so the questions that should shape a concept often arrive after the concept is already drawn.
The Site Pack App turns a site into one structured evidence pack a person can read and check. It gathers the parcel facts, a terrain summary, planning flags, an evidence table, and a concept-readiness note, with the gaps stated rather than hidden. This preview runs on sample sites: a Queenstown hillside section, an urban infill lot, and a site next to a coastal hazard.
Load a sample site and the app lays out its facts with a source label on each one. Adjust the proposed height or floor area and the readiness and missing-information lists update against it, so you can see what a given ambition does to the constraints. When the pack is useful, it exports as a short Markdown site summary that can leave the screen.
Every figure carries a source label or an assumption label, and anything the pack does not know is named as missing rather than filled in. The output is concept-stage and source-aware, not consent-ready. It still needs a surveyor, planner, engineer, and council to confirm it before it counts as more than early evidence.
Whether a site can become a reviewable pack that a team trusts at concept stage, and whether the tool can stay honest about what is confirmed against what is assumed. The next step is to move it off sample data and onto a real parcel, with LiDAR terrain and planning layers, while keeping the same discipline about sources, gaps, and review.
