Two 8.2 ft parasols instead of one
Record demo-neighbour-glass-glare:1:parasol-cluster:9:17
Two parasols about 8.2 feet across, set 7.2 feet apart along the table. Between them they cover a rectangle, which is the shape a table actually is.

Survey standing: Mapped: Shade, sky view and daily light are computed from real geometry rather than assumed. This is the rung at which the product starts telling you things you did not already know.

It earns its keep in 2 seasons and is roughly neutral in the rest.

Verification queue
- Who can actually see in. Sit where you actually sit and look around. Mark the one window or path you can see a person from. Until one exists, privacy is a question we are not answering rather than one that is fine.This is not a refinement. Nothing can answer this question until somebody marks it. · sit-there
- Neighbour's extension height. Measure how tall neighbour's extension actually is. A pole and a phone photo is enough.The verdict holds either way, but the margin moves by 21 points, which is the difference between comfortable and only just. · measure
Acceptance checks
- Re-run the reading for dinner outside at The table after installation and confirm the controlling failure is not worse than the tested proposal.
- Check the completed geometry against the decision record before accepting substitutions: width 8.2 ft, geometry note two canopies.
- Confirm the installed intervention preserves the tested annual behaviour (seasonal).
- Photograph the completed work from the original reading point and record any change to view, glare, privacy line or usable hours that the model did not predict.
Questions every bid should answer
- Still unanswered: privacy exposure, noise.?
- What exact product, fixing/anchoring method and maintenance regime is included in the price?
- Which dimensions or assumptions in this record would your proposal change, and why?
- What is excluded from the price: structural design, footing design, drainage, electrical work, planning/permit work, boundary verification or underground-service locating?
Explicit exclusions and professional boundaries
Two bases to move and two things to fold when it blows.
This decision record is design intent and decision evidence, not a construction drawing, structural calculation, permit set, boundary survey or setting-out document.
This record does not determine wind or snow loading, foundation or footing geometry, attachment adequacy, drainage works, electrical compliance, buried-service clearance, property lines or required approvals. Those questions remain with qualified people who can inspect the site and selected product.
