Why this result
The deck that eats furniture: not enough is mapped yet to say anything useful.
What you told it, and what it assumed
You told it
- The place is called “The deck that eats furniture”, in Austin (demonstration), America/Chicago.
- Lengths are shown in feet and inches.
- 1 private note is on this device. They stay in a project file unless you leave them out.
It assumed
- Nothing in the counted geometry is marked as placed by the model.
- Every counted object has some standing. That is not the same as every standing being a tape.
What it calculated
Calculated
- The deck that eats furniture: not enough is mapped yet to say anything useful.
What would change the answer
- A taped dimension where the plan still says estimated, placed, or unknown.
- Running the same change through a month that is not this one. A July gain is not a year.
Smallest next check
- The next useful check is the object whose standing is still unknown or estimated, measured at the place.
Where it stops, and which sources it used
Stops
- This is a decision instrument. It models sun, shade, sightlines, radiant heat and drying from the geometry it was given. It is not a structural, drainage, electrical or planning assessment, and it does not replace one.

The property, as mapped
The deck that eats furniture at Austin (demonstration). 2 places are being read, against 2 things that stand in the way.
| The house | 19 ft 8 in | 100 per cent solid. Confirmed. |
|---|---|---|
| Live oak | 33 ft | 80 per cent solid. Confirmed. |
How The outdoor sofa behaves in October
Read for 30 October 2026, in America/Chicago, northern hemisphere. This is the day the place is reading, not the fifteenth that stands in for the month, and not a forecast for that date.
The sun reaches this spot from 8:00 AM and leaves it at 6:40 PM. The sun reaches the outdoor sofa at 7:44 AM. The outdoor sofa loses the sun at 4:13 PM because of the Live oak. The outdoor sofa comes back into the sun at 5:53 PM, once the Live oak is no longer in the way. The outdoor sofa loses the sun at 6:43 PM.
| When this was read | 30 October 2026 | America/Chicago. Northern hemisphere. |
|---|---|---|
| Direct sun | 9.3 hours | of 11 hours of daylight |
| Sky visible from here | 76 per cent | The house takes 76%, Live oak takes 24% |
| Usable light | 21.5 mol/m² a day |
Whether it works for leaving things out
The outdoor sofa is on the edge for leaving things out over a year here, and hours of surface heat is why.
| Hours of surface heat | about 8h — 3h over (at most 5h) | Heat cycling opens joints, lifts finishes and warps boards. |
|---|---|---|
| How long it stays wet | about 13h — 1h over (at most 12h) | Repeated wetting with slow drying is what actually destroys outdoor things, far more than rainfall totals. |
| Ultraviolet dose | 1.1 MJ/m2/day — 0 MJ/m2/day over (at most 1.1 MJ/m2/day) | Ultraviolet dose is cumulative and does not care whether anyone is sitting there. |
What survives out here
Ultraviolet is the dominant pressure here. Colour goes first, then the fibre or the finish. Natural rattan, jute and untreated rope is the family this place punishes hardest. Family behaviour is a starting point. The exact product still decides the outcome.
| Tempered glass | well suited | The surface here peaks near 152°F. Ask the supplier: What is the edge detail, and how will it be cleaned on the outside face? |
|---|---|---|
| Weathering steel | well suited | The surface here peaks near 152°F. Ask the supplier: Is this a genuine weathering grade, and what does the datasheet say about wet-dry cycling and about run-off staining? |
| Exterior porcelain paver | workable | The surface here peaks near 152°F. Ask the supplier: What is the slip classification, wet, and how is it being laid: pedestals, sand or mortar? |
| Stainless steel | workable | The surface here peaks near 152°F. Ask the supplier: Is it 304 or 316? Within a few miles of salt water that difference is the whole decision. |
| Gravel and self-binding aggregate | workable | The surface here peaks near 152°F. Ask the supplier: What size and shape is the aggregate, and is there an edge to keep it where it belongs? |
| Sling and mesh fabric | workable | The surface here peaks near 152°F. Ask the supplier: What holds the sling to the frame, and can that fixing be replaced when the fabric goes? |
What belongs here
About 29.9 moles of usable light a day with about 13 hours of direct sun in high summer. That is full sun, whatever the label on the plant says. Midwinter direct sun is about 10 hours, counted on its own day, not inferred from summer.
Of the groups in the reference set, shade-tolerant lawn or alternative is the one that actually belongs in conditions like these.
| Shade-tolerant lawn or alternative | belongs here | Surfaces here reach about 152°F. A container in that is a watering commitment, not a planting decision. This spot sits wetter than this group tolerates. Wet feet kill far more plants than cold does. Examples, not recommendations: Fine fescue mixes; Clover and micro-clover blends; Moss, accepted rather than fought. |
|---|---|---|
| Contained clumping bamboo | belongs here | Surfaces here reach about 152°F. A container in that is a watering commitment, not a planting decision. This spot sits wetter than this group tolerates. Wet feet kill far more plants than cold does. Examples, not recommendations: Clumping Fargesia. |
| Large-leaved subtropical foliage | belongs here | This spot sits wetter than this group tolerates. Wet feet kill far more plants than cold does. Surfaces here reach about 152°F. A container in that is a watering commitment, not a planting decision. Examples, not recommendations: Banana in frost-free climates; Fatsia in shade; Canna as a summer plant. |
| Rain garden and swale planting | will work | Surfaces here reach about 152°F. A container in that is a watering commitment, not a planting decision. Zone 9.1 is outside this group's usual range of 3 to 9. Hardiness is a floor, not a plan. Examples, not recommendations: Iris in damp ground; Switchgrass; Joe Pye weed in North America. |
| Medium deciduous shade tree | will work | Zone 9.1 is outside this group's usual range of 4 to 9. Hardiness is a floor, not a plan. This spot sits wetter than this group tolerates. Wet feet kill far more plants than cold does. Surfaces here reach about 152°F. A container in that is a watering commitment, not a planting decision. Examples, not recommendations: Field maple; Serviceberry; Hop hornbeam. |
| Moisture-loving marginal | will work | Surfaces here reach about 152°F. A container in that is a watering commitment, not a planting decision. Zone 9.1 is outside this group's usual range of 3 to 9. Hardiness is a floor, not a plan. Examples, not recommendations: Astilbe; Ligularia; Iris sibirica. |
What to measure before spending anything
Ranked by how far the answer actually moves across the plausible range, not by a checklist.
| Who can actually see in | sit there | 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. |
|---|---|---|
| What you are looking at | sit there | 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. |
| Live oak height | measure | 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. |

Where this stops
- This is a decision instrument. It models sun, shade, sightlines, radiant heat and drying from the geometry it was given. It is not a structural, drainage, electrical or planning assessment, and it does not replace one.
Who to ask, and what to ask them
Everything this reading cannot answer goes to 4 places: a structural engineer, a drainage engineer, an electrician and your planning authority.
Inferred from the time zone America/Chicago. A time zone identifies a country reasonably well and a county not at all, so nothing below is local to you.
A licensed professional engineer (PE), structural
Whether a wall, deck, post or fixing carries the thing you are proposing is a calculation about materials and connections. This product models sun, wind exposure and sightlines; it has never been told what the wall is made of or how the deck is framed.
Take these questions
- Will this fixing or footing carry the load, in the wind this site actually gets?
- What has to be opened up or exposed before that can be answered?
- Is there a version of this that avoids a structural question altogether?
Take these with you
- The contractor packet from this property, which has the dimensions and where each came from
- Photographs of the wall or frame the thing would fix to
- Anything you know about what is behind the surface
Where the register is
NCEES — licensure and verification — Licensing is by state; this points at the board that holds your state's register.
The line in this document that sends you here

A drainage contractor or civil engineer
This product reads how long a surface stays wet from sun, shelter and shade. It does not know where the water goes afterwards, what the ground is made of below the top few inches, or what your drains are connected to.
Take these questions
- Where is this water going now, and where would it go after the change?
- Is there a connection or a soakaway involved, and is that something I am allowed to alter?
- What would a percolation or infiltration test cost here before anybody designs anything?
Take these with you
- The wetness reading and the months it is worst in
- Where the downspouts land and where water stands after rain
- Any drainage drawing that came with the property

A licensed electrician
Outdoor lighting and anything powered near water is a wiring question with a legal answer, and this product models the light rather than the circuit.
Take these questions
- Is this circuit suitable for outdoors and for the distance involved?
- What protection does this need, and does the work have to be certified or inspected?
- Can the fixture be aimed or shielded the way I need without changing the wiring?
Take these with you
- Where the fixtures would go and what they are pointed at
- The distance from the nearest existing supply
Where the register is
Your state or county building department — Permitting and licence checks are local; the state consumer office lists who holds them.

- This is a decision instrument. It models sun, shade, sightlines, radiant heat and drying from the geometry it was given. It is not a structural, drainage, electrical or planning assessment, and it does not replace one.
Your city or county planning and building department
Whether you are allowed to build a thing is decided by a local rule set that varies street by street. This product has no idea which rules apply to your address, and anything it said about consent would be a guess dressed as an answer.
Take these questions
- Does this need consent at this height, this footprint and this distance from the boundary?
- Is there anything specific to this property — a conservation designation, a covenant, an easement, an HOA rule?
- If it does not need consent, is there anything that would make it need one?
Take these with you
- The dimensions and the position relative to the boundary, which the contractor packet already states
- A site plan showing where it sits
- The property address, which is what everything above is actually keyed to
Where the register is
USA.gov — find your local government — Permits and setbacks are city or county; this finds the office that issues them.

Nothing here says what the answer will be. These are registers rather than recommendations, and a name on one is a qualification rather than an endorsement.
