A second seat 19.7 ft east
Record demo-carport-conversion:1:second-seat:9:17
Put two chairs 19.7 feet to the east and leave the main table where it is. The point is not to fix this spot but to stop needing it at the hour it does not work.

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.

This is a real seasonal trade: it helps in 1 season and hurts in 3.

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
- What you are looking at. Mark the direction of the view worth keeping. Without it, every screening recommendation is optimising against nothing.This is not a refinement. Nothing can answer this question until somebody marks it. · sit-there
Acceptance checks
- Re-run the reading for dinner outside at The table under the roof 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: distance from reading point 19.7 ft, bearing 69°.
- Do not sign off the intervention from the installation-season result alone; this proposal has a known seasonal tradeoff in the annual comparison.
- 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
- How will you verify: Somewhere else on the property that behaves differently?
- Mark 6 metres out on the ground and stand there before committing. The geometry is only as good as that distance.?
- Still unanswered: privacy exposure, view, 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
Only worth it if the second spot genuinely behaves differently. The comparison below says whether it does.
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.
