The hedge that browns on one side every winter
Buy nothing yetMove the table before you buy the pergola.
Before you buy a pergola, move the table.
Every change below is put into the plan and the whole model is run again. That is why a pergola's winter cost shows up here without anybody having written it down, and why the cheapest thing that actually buys hours back is allowed to win.

Where it stands now
Something left out here
The seaward face works for leaving things out across the year.
“Works” means the model's weighted checks support this use, and no reading is past its own limit. A reading listed as close still needs attention; it does not mean every reading passed.
Close to the limit Ultraviolet dose is 1.4 MJ/m2/day — 0.3 MJ/m2/day over (at most 1.1 MJ/m2/day)Worked out: Computed from the geometry, the sun and the weather you gave it.
This spot takes a hard ultraviolet dose. Fading and finish breakdown are the first things you will see, long before anything structural.
Ultraviolet dose is cumulative and does not care whether anyone is sitting there.
Close to the limit How long it stays wet is about 14h — 2h over (at most 12h)Estimate: Worked out, but at least one input was assumed rather than measured.
An outdoor cushion soaked here in Jan would not dry before nightfall.
Repeated wetting with slow drying is what actually destroys outdoor things, far more than rainfall totals.
What would change this. This would change if ultraviolet dose moved. A reversible test is how you find out whether the model named the right mechanism.
Confidence low (43%). Treat this as a starting hypothesis, not an answer.
