The outdoor sofa for Something left out here. October 30, 2026 at 3:00 AM, America/Chicago. Now on this date. Confidence low. Cause: Hours of surface heat is what stops it.

Furniture, cushions, a rug, a finish. What this place does to it over a year.

Something left out here

The outdoor sofa is on the edge for leaving things out over a year here, and hours of surface heat is why.

“Tight” means the use is borderline, or a reading is already past its own limit. The controlling limit is named below.

  • Past the limit Hours of surface heat is about 8h — 3h over (at most 5h)Estimate: Worked out, but at least one input was assumed rather than measured.

    The surface here passes 113°F for about 8 hours, peaking near 150°F. That is the number that matters for bare feet, paws and anything resting on it.

    Heat cycling opens joints, lifts finishes and warps boards.

  • Close to the limit How long it stays wet is about 13h — 1h 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.

  • Close to the limit Ultraviolet dose is 1.1 MJ/m2/day — 0 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.

What would change this. This would change if hours of surface heat were measured and came out differently. The figure is an estimate, not a tape.

Confidence low (43%). Treat this as a starting hypothesis, not an answer.

What next here

Testing a change

3 of 8 milestones. One thing is still in the way of privacy, sightlines and screening advice.

  1. Getting an honest answer3 of 4 done
    • Placed on the earth — done. The sun is in the right part of the sky for this address.
    • A spot to read — done. 2 spots are being read.
    • What stands in the way — done. 2 things are drawn, so the shade is worked out rather than assumed.
    • Who can see in — not done. Privacy is the most common reason a terrace goes unused, and it cannot be answered without knowing which windows look at it.
  2. Testing a changeyou are here0 of 2 done
    • A change tested — not done. Testing a change before buying it is the cheapest part of the whole exercise.
    • A forecast checked — not done. A forecast nobody goes back and checks is a guess with a date on it.
  3. Proving it well enough to spend money0 of 2 done
    • Corrected against reality — not done. After a couple of rechecks the model can be corrected against this specific garden.
    • Photographed — not done. A photograph is what turns a drawing somebody sketched into a drawing somebody can check.
  1. Mark the windows that look at this spot

    Being overlooked is one of the most common reasons a good terrace goes unused, and it is the one reading here that cannot be inferred from anything else.

    a tap per windowneeded for privacy, sightlines and screening advice
  2. Read all 2 spots at the same hour

    Moving where you sit is free, immediate and reversible, and it beats most of what you could build. Read side by side it is usually obvious which corner was always going to work.

    a read, nothing to enter
  3. Get this place to Annotated

    A photographic check on the mapped sightlines and geometry. That makes privacy estimates more credible, but does not replace measured dimensions. Right now: Sightlines drawn from mapped observers remain provisional until their positions and heights are checked. The drawn heights have not been verified against the actual place. What is missing: Photographs of the actual place: None annotated. A photograph is how a drawn height gets checked against a real one. Photographs that know where they were taken from: No photograph has a position and a bearing, so what is marked on them cannot become a measurement. Who can see in: Nobody marked. Privacy is a question about who sees in from where, and the product will not invent one.

    3 things left
3 more things worth doing here
  1. Test a change before you buy anything

    The plan is good enough to ask what a screen, a tree or a canopy would actually do here — including the ones that turn out to be a waste of money.

    a few minutes, nothing bought
  2. See how this spot changes through the year

    A terrace that works in July can be unusable in September for reasons that have nothing to do with temperature. The same geometry read in four seasons is the cheapest insight here.

    a read, nothing to enter
  3. Photograph the spot and mark what is in shot

    A photograph is what separates a drawing you sketched from a drawing somebody else can check. It is also how heights get corrected without a ladder.

Shade, sky view and daily light are computed from the geometry on this plan. Unmeasured dimensions remain estimates, not verified measurements.

Sightlines drawn from mapped observers remain provisional until their positions and heights are checked. The drawn heights have not been verified against the actual place.

To reach Annotated

  • Photographs of the actual place: None annotated. A photograph is how a drawn height gets checked against a real one.
  • Photographs that know where they were taken from: No photograph has a position and a bearing, so what is marked on them cannot become a measurement.
  • Who can see in: Nobody marked. Privacy is a question about who sees in from where, and the product will not invent one.

What that buys: A photographic check on the mapped sightlines and geometry. That makes privacy estimates more credible, but does not replace measured dimensions.

Everything that was checked
  • Quick A place on the earth: Austin (demonstration), with a time zone, which is what makes an hour an hour.
  • Quick Somewhere to read: 2 spots marked. A reading is a height at a place, and moving it moves the answer.
  • Mapped The things in the way: 2 objects drawn. The house counts, and so does the neighbour's.
  • Mapped What is underfoot: 2 of 2 readings sit on a mapped surface.
  • Mapped Where the property ends: Drawn, so the product can tell you when the cheapest fix stands on someone else's land.
  • Annotated Photographs of the actual place: None annotated. A photograph is how a drawn height gets checked against a real one.
  • Annotated Photographs that know where they were taken from: No photograph has a position and a bearing, so what is marked on them cannot become a measurement.
  • Annotated Who can see in: Nobody marked. Privacy is a question about who sees in from where, and the product will not invent one.
  • Measured Heights off a tape: 0 of 2 objects are measured. The remaining 2 are this product's own inference, so no figure here is a survey figure yet.
  • Measured Something checked against the day: Nothing has been checked against a real afternoon. The model is unopposed, which is not the same as being right.

What to measure next

Ranked by how far the answer moves, not by a checklist
  1. 1Who can actually see inSit in the chair

    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.

    Mark it on the plan

    Currently assuming: nobody is overlooking this. Tested across one confirmed observer changes the whole privacy answer.

  2. 2What you are looking atSit in the chair

    Mark the direction of the view worth keeping. No view has been marked yet, so nothing weighs what the view is worth, and a screen that blocks it looks free.

    This is not a refinement. Nothing can answer this question until somebody marks it.

    Mark it on the plan

    Currently assuming: no view is being protected. Tested across one corridor changes what screening is worth doing.

  3. 3Live oak heightTape measureUltraviolet dose ±6

    Measure how tall live oak actually is. A pole and a phone photo is enough.

    The verdict holds either way, but the margin moves from comfortable to only just. Worth confirming.
