Property exposure brief
The carport we are trying to eat in
The table under the roof cannot be answered for dinner outside yet.
The property, as mapped
The carport we are trying to eat in at New York (demonstration). 1 places are being read, against 4 things that stand in the way.
| The house | 19.7 ft | 100 per cent solid. Confirmed. |
|---|---|---|
| Carport roof | 9.2 ft | 100 per cent solid. Confirmed. |
| Corner post | 8.2 ft | 100 per cent solid. Confirmed. |

How The table under the roof behaves in September
The table under the roof cannot be answered for dinner outside yet.
Nothing in September clears what dinner outside needs here.
The sun reaches this spot from 7:40 AM and leaves it at 9:00 AM. At 9:09 AM it goes into shade because of Carport roof.
| Direct sun | 1.7 hours | of 12.3 hours of daylight |
|---|---|---|
| Sky visible from here | 6 per cent | Carport roof takes 77%, The house takes 22%, Corner post takes 0% |
| Usable light | 1.7 mol/m² a day |
Whether it works for dinner outside
We cannot say yet whether The table under the roof works for dinner outside, because privacy exposure is still unanswered.
What to try, cheapest first
Nothing tested moves this materially, which usually means the limit is real rather than fixable by an object.
| Move the table 6.6 ft east | +0 | move it. It does not meaningfully change the beam in either season. |
|---|---|---|
| Sit under Carport roof | +0 | move it. It does not meaningfully change the beam in either season. |
| A 9.8 ft umbrella | +0 | an afternoon. It does not meaningfully change the beam in either season. |
| Shield Strip light | +0 | an afternoon. It does not meaningfully change the beam in either season. |
| Two low shielded lights instead of one high one | +0 | an afternoon. It does not meaningfully change the beam in either season. |
| A shade sail over the seating | +0 | a project. It does not meaningfully change the beam in either season. |
What survives out here
Things stay wet here for 12 months of the year. That, and not rainfall, is what decides what survives. 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.
| Stainless steel | well suited | Anything that stays damp grows something, whatever it is made of. Ask the supplier: Is it 304 or 316? Within a few miles of salt water that difference is the whole decision. |
|---|---|---|
| Powder-coated aluminium | well suited | Anything that stays damp grows something, whatever it is made of. Ask the supplier: Is the powder coat rated to AAMA 2604 or 2605, and is the substrate marine-grade? |
| Weathering steel | well suited | Anything that stays damp grows something, whatever it is made of. Ask the supplier: Is this a genuine weathering grade, and what does the datasheet say about wet-dry cycling and about run-off staining? |
| HDPE and polypropylene resin furniture | well suited | Anything that stays damp grows something, whatever it is made of. Ask the supplier: Is it ultraviolet-stabilised, and what does the fade warranty say in years? |
| Hot-dip galvanised steel | well suited | Anything that stays damp grows something, whatever it is made of. Ask the supplier: Is it hot-dip galvanised or electroplated? The difference in service life is measured in decades. |
| Tempered glass | well suited | Anything that stays damp grows something, whatever it is made of. Ask the supplier: What is the edge detail, and how will it be cleaned on the outside face? |
What belongs here
About 1.9 moles of usable light a day with about 2 hours of direct sun in high summer. That is deep shade, whatever the label on the plant says.
Nothing in the reference set is a clean match here, which usually means the light or the drainage has to change first. Anything planted here sits wet for 12 months of the year, so drainage is the decision before the plant is.
| Deep-shade foliage plant | marginal | This spot gives about 1.9 moles a day and this wants at least 2. It will live and it will not perform. Examples, not recommendations: Hart's tongue fern; Epimedium; Asarum. |
|---|---|---|
| Fern for cool damp shade | marginal | This spot gives about 1.9 moles a day and this wants at least 3. It will live and it will not perform. Examples, not recommendations: Dryopteris; Polystichum; Athyrium. |
| Broad evergreen hedge | wrong place | This spot gives about 1.9 moles a day and this wants at least 10. It will live and it will not perform. Examples, not recommendations: Yew; Portuguese laurel; Holly. |
| Deciduous hedge that holds its leaves | wrong place | This spot gives about 1.9 moles a day and this wants at least 10. It will live and it will not perform. Examples, not recommendations: Beech; Hornbeam. |
| Evergreen structural shrub | wrong place | This spot gives about 1.9 moles a day and this wants at least 8. It will live and it will not perform. Examples, not recommendations: Box alternatives such as Japanese holly; Pittosporum; Osmanthus. |
| Part-shade perennial | wrong place | This spot gives about 1.9 moles a day and this wants at least 6. It will live and it will not perform. Examples, not recommendations: Hellebore; Geranium; Hosta where slugs allow. |
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. Without it, every screening recommendation is optimising against nothing. This is not a refinement. Nothing can answer this question until somebody marks it. |

Where this stops
- Anchoring and wind rating are the manufacturer's numbers, not ours. A cantilever umbrella in gusty conditions is a real hazard.
- Anything involving permanent wiring is an electrician's work.
- Permanent exterior circuits need code-compliant wiring.
- Sail tension pulls hard on its anchors. Fixing points into a wall, a post or a tree is a structural decision.
- 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 6 places: a structural engineer, a drainage engineer, an electrician, your planning authority, an arborist and the manufacturer.
Inferred from the time zone America/New_York. 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.

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.

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.

A certified arborist
This product models a canopy as a shape that blocks light. Whether a tree is safe, whether it will survive what you are proposing, and whether you are permitted to touch it are three separate questions it cannot answer.
Take these questions
- Is this tree safe as it stands, and does the answer change if I build near it?
- What will this do to the root zone, and how far out does that reach?
- Is this tree protected, and by what?
Take these with you
- The canopy dimensions this product is using and where they came from
- Photographs of the whole tree, including the base
- What you are proposing to build and how close
Where the register is
ISA — find an arborist — The certification register, including the tree-risk qualification.
The line in this document that sends you here
- Sail tension pulls hard on its anchors. Fixing points into a wall, a post or a tree is a structural decision.
The manufacturer or an approved installer
Wind ratings, fixing patterns and warranty conditions belong to whoever made the thing. This product can say what a change would do to the reading; it cannot say what voids the guarantee.
Take these questions
- What is the wind rating, and in what mounting?
- What does the warranty require of the installation and the maintenance?
- What is the actual lead time and what does it look like in five years?
Take these with you
- The exposure this product measured, including the windiest month
- The fixing surface you actually have
No register is named here, because this router does not know which country holds one for you. The questions above are the same wherever you are.
The line in this document that sends you here
- Anchoring and wind rating are the manufacturer's numbers, not ours. A cantilever umbrella in gusty conditions is a real hazard.
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.
