Face the seating east

Turn the chairs to look east, which puts the low sun behind the shoulder instead of across the table.

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.

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 reading for an hour at The bench in the shade 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: bearing 80°.
- Confirm the installed intervention preserves the tested annual behaviour (robust).
- 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
No view corridor is marked, so this only optimises against the sun.
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.
