Google Sheets Pole Barn Estimator

I want a single Google Sheets workbook that turns a few simple inputs—width, length, wall height, roof pitch and the like—into a fully costed materials list for a pole barn. The sheet has to let me pick between gabled and single slope roofs, choose whether the structure is fully enclosed, partially enclosed, or open on all sides, and add lean-tos that may be attached (single or double) or freestanding. Once I fill in those choices the sheet should instantly calculate the quantity of posts, trusses, purlins, wall girts, metal panels, trim, concrete and hardware. Those quantities have to follow the engineering spacing rules we already use in house, then pull current unit prices from my supplier table on another tab and roll everything into a clean total. A few technical expectations: • Google Sheets formulas should do most of the heavy lifting, but feel free to add Apps Script where native functions fall short (for example, dynamic lookup of price tiers or conditional formatting for stock warnings). • All constants—spacing rules, load tables, waste factors, price lists—need to sit in a clearly labelled data area so I can update them without touching the logic. • The user-facing inputs and the resulting materials / cost summary should be laid out intuitively; this will be used daily by sales staff who are not spreadsheet gurus. • Documentation inside the sheet (or a short PDF) must explain how each major calculation works so I can audit or tweak it later. I’ll provide my current engineering tables and price lists once we start. If you’ve built construction or manufacturing calculators in Google Sheets before, especially anything that factors in multiple roof styles and enclosure options, your experience will be a big plus. Looking forward to turning this estimate process into a one-click job.
