Useful tools, clear boundaries
A focused workbench
BuildBench turns room measurements into a first shopping estimate. Its formulas make waste allowances visible and round indivisible packs upward. It is for materials planning rather than structural engineering: measure on site, check product labels, and confirm special layouts before ordering.
What you can do here
The current collection includes paint estimator, flooring packs, tile count, concrete volume, wallpaper rolls. Each tool has its own page, a worked example, and a clear explanation of its method.
How results are produced
The site uses JavaScript for local calculations and plain HTML for guides and navigation. No account is needed. We label assumptions and check inputs, while acknowledging that floating-point arithmetic, rounding, and real-world conditions affect how a result should be interpreted.
Corrections and feedback
