What are you building?
Every material in view. Checked product evidence where available. No missing item quietly treated as free.
Product evidence, not an installation plan
Boilers, without bundle confusion
Exact model and SKU observations, what the pack includes, and what still needs a separate price.
Public product readings · dated and qualifiedA fast, measured benchmark
Compare five deck prices
Change dimensions and building quantity to compare a partial OSB3 floor or roof package across five merchants.

Boiler SKU readings
Different models and pack contents are not ranked as interchangeable boilers.
100 independently authored starting points
Find your work. Start with its materials.
24 working specification checklists + 76 scoping ideas. Not a sales ranking, 100 priced designs or a claim of live inventory.

A useful budget, with its gaps in plain sight. Public observations are dated—not a guaranteed quote or continuously live feed. Current stock, account terms, rebates, pack identity and delivery must be checked before purchase.
Materials buying map · no labour
The workshop. Every buying line in view.
33 inventory lines, their SKU candidates and a transparent priced subtotal. Unknown quantities, missing products and incomplete merchant coverage stay visible.
Labour excluded
Illustrative DIY buying scope—not the kit’s bill or an approved construction plan.
Window apertures and structural / fixing quantities remain unverified. 18mm OSB3 is a proposed alternative to the related kit’s 12mm T&G—not an exact reproduction.
Starting dimensions and assumptions
The 15 × 30 ft dimensions are a starting interpretation, not confirmed external measurements. Default eaves 2.1m, roof rise 0.61m, overhang 0.15m and door opening 1.4 × 1.8m are editable illustration assumptions—not manufacturer specifications. Six windows are declared; aperture dimensions remain unknown. A reviewed specification must establish framing, supports, loads, cutting layouts and compatible fixing counts.

Blank means unknown. Drawing fallbacks are not saved as measurements. Window positions, opening structure, framing, spans and usable cutting layouts need independent review.
Internal kit eaves and ridge heights are not automatically external design dimensions. Every change needs a renewed quantity and quote review; this sketch does not establish building-regulation or planning compliance.

Calculation, source and scope limitations
Surface allowance is not a cutting plan. Each material pack is rounded up per building before multiplication; offcut reuse is not assumed. Structural and fixing quantities are buyer-declared, not reverse-engineered from a photograph.
Known checked-lines subtotals do not prove one obtainable basket, a complete project or cheapest delivered order. Merchant-specific eligibility, source age, exact packs, compatibility and stock can exclude an observation. A buyer compatibility declaration is not certification.
This 33-line view uses curated source records only; it cannot yet accept a new merchant quotation against every missing subline. Use the cumulative advanced quote worksheet for your own specified materials and missing prices. Its separately scoped comparison does not automatically complete this inventory.
Public-price observations are dated snapshots. No automatic hourly feed or full UK inventory connection is claimed. This route excludes labour entirely; it does not hide labour inside a total.

Partial roof/floor materials, not a complete shed quotation.The related supplier kit uses 12mm tongue-and-groove timber; the requested B&Q kit’s exact construction is unverified. These 18mm OSB3 boards are a proposed design alternative, not the same construction or a confirmed substitute.

How the allowance is calculated—and what is missing
Floor and roof sheet allowances are rounded up separately for each building before multiplying by building quantity. No offcut reuse between decks or buildings is assumed. The allowance uses the stated footprint, selected deck areas and waste percentage. It is not an optimised cutting layout, purchase reservation or structural certification.
Excluded from this package: base and groundworks, framing, walls/cladding, doors, windows, roofing membrane, fixings, tools, labour and delivery. Board support, edge treatment, weather protection and cuts need a competent design review. No complete workshop cost is calculated.

Read published details where supported. A photo or product page cannot reveal a safe construction design or a complete cut list.
Your inputs clear on refresh. No account passwords, customer details or private employer terms.
WHAT THE SOURCE ACTUALLY SAYS
Facts first. Assumptions visible.
The source brief will appear here. Only stated dimensions and specifications become source facts.
- No exact kit recreation inferred from an image.
- No missing price converted to zero.
- No invented SKU or merchant stock claim.
Evidence, assumptions and unresolved requirements
No product source has been read. Dimensions, specification and purchasing evidence are manual inputs.
Run the current comparison to produce the unresolved-requirement register. Saved scope quantities may remain available, but changed quotes never retain old cost results.
Kit wall thickness is not automatically equivalent to nominal merchant timber thickness. Product title similarity, old receipt prices and historical archive feeds are not current matching proof.
Show the workings
The server computes provisional floor, roof and wall areas from the declared geometry, then applies each line’s stated waste and project quantity. Manual framing, fixings and other unknown counts stay unknown. Every quote must cover the same measurement unit and declared requirement.
Whole purchasing packs are rounded up separately by merchant. Delivery or collection costs are evaluated for each merchant order. Missing, aged, expired, mismatched, ineligible and paid-receipt observations cannot become current comparable quotes.
This tool is a procurement aid, not structural design, a validated manufacturing plan, a complete SKU catalogue or a live checkout. Excluded scope, labour and other project costs must remain explicit. Your inputs are sent to the calculation service but this worksheet is not stored in a database; refresh clears it.

01 / DECLARE THE REQUIREMENT
Copper pipe run
Pipe lengths, fittings and supports—priced as separate variants.
Context stays with the checklist. It does not change quantities, approvals or price eligibility.
No guessed pack coverage or default waste. Each variant needs its own line. This is a material buying aid, not a design or installation guide.
02 / SPECIFY THE PURCHASING UNITS
Leave unknown quantities blank. Mark supplied or excluded items explicitly.
Generic material requirements. No catalogue SKU is invented or automatically matched.
What these templates do—and do not claim
The library groups common merchant categories into independently authored procurement checklists. It is not a proven ranking of best-selling products or a complete bill of materials. Copper and boiler examples are prioritised for the pricing complexity they expose, not an unverified sales claim.
Only whole purchasing units are transferred to the seven-line beta comparison. Prices still require product identity, VAT, pack contents, dated quote, eligibility, stock and fulfilment checks. Building context does not establish compliance. Your inputs clear on refresh; download the checklist to retain them.
Historic CPS, PTS and TP prices, private rebate schedules and original employer code are not included. Commodity prices and exchange rates do not automatically predict a customer ticket price.
