The priced materials, at the cheapest and priciest store
The plan is a 10 x 12 ft shed on skids, with 2x4 walls at 16 inches on centre and a single-slope roof. The quantities below are the usual order of magnitude for that plan, and your own drawing sets the real count.
For each item the table gives the cost at the cheapest and at the priciest Quebec store we track, seen between September 25, 2026 and October 13, 2026. No single store sells every item at its lowest price, which is the point of comparing store by store.

Unit prices tracked by Buildsavr at Quebec retailers, seen between September 25, 2026 and October 13, 2026: the lowest and the highest price we found for each item, each at a single store, so the two totals are a floor and a ceiling and no store sells the whole list at either. Before tax. This is NOT the cost of the shed: the floor, the rafters, the siding, the door, the fasteners and the roof membrane are not in it. Quebec prices only; we are rolling out province by province.
