A 12 × 10 ft shed on skids with a 6/12 hip roof, 120 sq ft of floor. 36 items in the list below, every one with its quantity and why.
Where these numbers come from. The floor, walls and roof are sized from the IRC 2021 tables and computed spans for No. 2 lumber, at the snow load the plan states. Those table values are still being checked line by line against the code book. Many towns need no permit for a small shed, but the size limit varies: check with your building department before you build.

Each phase builds on the one before, so there is always something solid to fix to.
The skids carry the whole shed, so they must sit level on a firm, draining base.
The floor is the base the walls are laid out on: it must be square.
The subfloor ties the frame together and is the deck the walls are built on.
Walls are framed flat on the floor, then stood up: square, plumb and braced before the roof goes on.
The roof frame has to be complete and tied down before sheathing stiffens it.
Sheathing braces the walls and roof and is the base for everything weather-tight.
Get the roof dry before the walls are finished.
Openings are flashed before the units go in, so water drains out, not in.
The siding is the weather face: trim first, then courses up from a level line.
Open this plan in 16Span and ask for changes in plain words, like "make it 2 ft deeper" or "add stairs on the left". The structure is checked again, and the materials and price follow.
