How a laundry room remodel composer works — five calculators plus three code-derived trades merged into one list
The laundry composer is hybrid. Pick the scope once and it delegates to five standalone calculators (drywall, paint, flooring, trim, interior doors), then derives the three trades with no calculator yet — plumbing, electrical, dryer vent — from code-anchored rules of thumb. Every merged line is tagged with its source.
What this diagram shows
A flow diagram of a laundry room remodel composer. On the left the scope is picked once — the typology, floor level (first floor, second floor, or basement), finish quality, and the plumbing and electrical adjusters. Those shared choices feed five standalone calculators drawn with solid outlines: drywall, interior paint, flooring, trim, and interior doors. Below them, three trades that have no standalone calculator yet are drawn with dashed outlines: plumbing, electrical, and dryer vent. The composer derives those three from code-anchored rules of thumb instead of a packaged calculator. On the right, all eight producers merge into one materials list where every line is tagged with its source — the calculator name for the delegated trades, or the word composer for the three derived ones. The composer never re-does the math it can delegate.
