A shell take-off and a sanity check, not a structural design, an electrical design or a planning decision.
Build it right first time — $9
Order the right lengths, cut each piece once and square the frame before you fix it. The Full Build Pack turns this drawing into the plan you build from.

How the cut list reads (example layout)
Each stock length the yard sells, with the pieces to cut from it and what is left over.

What $9 adds
- Dimensioned framing plan and the exact cut list, packed into stock lengths
- CSV merchant order file, ready for a supplier or spreadsheet
- Setting out: the diagonal to pull so the frame is square before anything is fixed
- Yard order sheet: only things a merchant can hand over, each line checked and in your own units, with a box to tick
- Build order: each stage in sequence, with the check that goes with it
- Your company name on the PDF and the shared page, with our line gone
Building it yourself? One length cut short costs more than this pack. You get the diagonal to square the frame, the counter sheet to tick off at the yard, and the order to build in.
Quoting a customer? The same job goes out under your own name, with our line gone. Per job, no subscription to start.
Still free: the 3D drawing, the take-off on screen, a summary PDF and your own prices.
Type in what your supplier charges and the room gets costed. Leave it empty and you keep the quantities only.
