Design took a slight detour - considered a solar system, mono pitch roof and orienting the building due south.
Current plan -
FULL spec
Less than 108 sf (to avoid building permit requirement)
Enclosed firewood storage
Winter storage for patio furniture or similar
Floating structure
Extra wide doors to accommodate contractor grade wheel barrow, etc
Optimise building longevity
Fully protect stud walls with siding
Protect siding from firewood stacking with interior battens
Diagonal siding battens for structural rigidity
MATERIALS
Sienna pressure treated / foundation wood, cottage pads, patio stones, asphalt shingles, OSB roof boards, interior spruce battens
AIRFLOW priority
As an enclosed firewood storage structure is a bit unknown to me, priority is given to optimising airflow
Underneath, Sides,
Top ventilation layer to minimise humidity build up in roof volume
Maximum 1" gaps to limit animal access to mice and small birds
