Partial estimate: some layers are unknown, so no U-value is calculated. Only the resistance of known layers is shown.

Thermal bridges through battens, edges and fasteners
Moisture, condensation and property changes of damp material
Heat produced by the animal
Wind and transient temperature changes
Assumptions
Thin layers without a sourced λ (roof covering, film, mat) are not counted.
The pallet is an unknown layer with voids; only known layers are counted.
Floor and roof are not insulated.
The estimate is not a temperature guarantee and does not claim the shelter is safe to any temperature.
Water and moisture
Weather exposure
A warm shelter that gets damp can be worse than a simpler one that stays dry. This is an explanation, not a condensation calculation.
✓Ground contactRaised about 144 mm off the ground.
✓Rain splashHigh enough that rain splash from the ground does not hit the floor.
✓Roof drainageThe roof falls from the entrance to the rear, so water runs off away from the entrance.
!Rain at the entranceLow sill: rain and snow get in more easily; turn the entrance away from wind.
!DryingWithout a service opening drying and cleaning are harder; change bedding through the entrance.
!Absorbent materialThe material absorbs moisture; check it more often and replace it when damp.
!Maintenance accessLeave room around the house for checks and cleaning.

Placement
Check the spot
No obvious issue detected
This is not a safety certificate for the spot: it only means none of the listed questions is ticked.
Bedding
What goes inside
RecommendedStrawRepels moisture and stays loose. Replace when damp, compacted or soiled, and when seasons change.
Not recommendedHaySoaks up moisture, turns cold and can mould. If already in a shelter, replace it with straw.
Not recommendedBlanketAbsorbs and holds moisture; a damp blanket chills. Wash and swap as soon as it is damp.
Not recommendedTowelAbsorbs moisture like a blanket. Wash and swap as soon as it is damp.
Not recommendedWood shavingsPartly absorbs moisture. Change when damp or compacted.
Not recommendedWashable dog bedDepends on fabric; textile absorbs moisture. Dry or swap as soon as it is damp.
Not recommendedNo beddingNothing to absorb moisture. Not applicable.
Maintenance
Inspection schedule
WeeklyCheck that the straw is dry and loose; replace it when damp or compacted.
WeeklyCheck for water or dampness on the floor and walls, especially under the entrance.
After stormsAfter rain or snow check the interior and the ground under the shelter.
MonthlyCheck the roof covering, overlaps and that water runs off at the rear, away from the entrance.
MonthlyCheck that screws and nails are tight and no tip protrudes.
MonthlyCheck edges: no splinters, cracks or swollen areas.
After stormsClear snow from entrances and exits so the animal cannot be snowed in.
Each seasonClean the interior; service access must allow cleaning without dismantling.

Where to go next
Each step states what you add, what you gain and what stays limited. A new model has a new plan ID; changing an existing build has no canonical plan.

Inspect the pallets
Every pallet must pass the checklist: no stains, chemical smell, oil, rot or mould. An ISPM 15 mark confirms only a phytosanitary treatment, not the pallet's history.
Cut the pallet sections
Cut sections per the cut list so a stringer or block remains at each end. Remove protruding nails and sand the edges.
Assemble the frame
Set the floor pallet level, fix the back and side sections onto it and tie the corners with battens. The front sections leave the entrance opening.
Insulate the cavities
Cut insulation boards to fit between the pallet stringers and place them in the wall cavities.
Close the gaps outside
Fix cladding on the outside so wind and rain cannot pass through the gaps between boards.
Interior lining
Fit an interior lining so the animal touches neither insulation nor rough pallet parts.
Roof falling to the rear
Fit two tapered battens so the roof falls 60 mm to the rear, then fix the roof board and covering. Water must run off behind the house, away from the entrance.
Add straw, not hay
Loosely fill straw to a quarter or half of the interior height. Do not use hay, towels or blankets in an outdoor winter shelter: they absorb moisture and chill.
Choose the spot and secure it
Set it against a wall or fence, out of the wind, away from roof runoff and roaming dogs. Weight or secure lightweight shelters. Check the spot with the placement checklist.

A source supports a guideline or material value, but it does not confirm this specific model. Container sizes are assumptions and build time is a planning estimate.
