Renovation Quote Template: Room-by-Room Scope Written With AI

Write one scope block per room, in the order the trades arrive: strip-out, first fix, plaster, second fix, decorating. Each block names what is included, what is excluded, which items are provisional sums and what you assumed about the site. Let AI draft the wording from your survey notes, then check every quantity and price yourself.

Disputes on renovations rarely start with the total. They start with a sentence two people read differently: "making good", "allow for tiling", "new electrics". AI is useful because it writes the same fields in the same plain style for every room. It is poor at knowing what sits behind the plaster, so the facts come from you and only the wording comes from the model.

Where renovation disputes start: the seams between trades

A single lump sum with a list of jobs underneath it leaves seams. A seam is the point where one trade stops and the next starts, and nobody has said who owns the gap. Most renovation arguments sit in a handful of them, and a room-by-room quote makes you name each one in writing before the work starts.

The pattern is the same in every row: a sentence with an owner, a boundary and either a figure or a rule. That is the unit of work for the AI. You are not asking it to "write me a quote". You are asking it to write each seam as a sentence with an owner and a boundary, from facts you supply. A blank template cannot do that, because the seams are different in every house.

The room block: eight fields every room carries

Every room gets the same eight fields in the same order. The sameness is deliberate. The customer learns where to look, you can see a blank field at a glance, and the model has a fixed shape to fill.

1. Room and size, as measured on the survey, for example "Bathroom, 2.1 m by 1.8 m, ceiling 2.4 m".
2. Working order: only the stages that apply to this room, from strip-out through decorating.
3. Included: one sentence per line, each starting with a verb ("Remove", "Fit", "Skim").
4. Excluded: named items, never "anything not mentioned".
5. Allowances: each prime cost sum and provisional sum with an ID, a figure and a settlement rule.
6. Assumptions: what must be true for the price to hold, and what happens if it is not.
7. Customer decisions: what you need from them and the date you need it by.
8. Protection and access: floor protection, dust control, working hours, water and power shut-offs.

ROOM: [name, size as measured]
STRIP-OUT
- [verb-first lines]
FIRST FIX
- [verb-first lines]

SECOND FIX

DECORATING

EXCLUDED
- [named items]
ALLOWANCES
- PC-01 [item], supply only, allowance $[amount]. Settlement: [rule]
- PS-01 [work], allowance $[amount]. Settlement: [rule]
ASSUMPTIONS
- [condition] ... if not, [consequence]

- [decision] by [date], or [consequence]
PROTECTION AND ACCESS

STAGE TOTALS
Strip-out $[ ] | First fix $[ ] | Plaster $[ ] | Second fix $[ ] | Decorating $[ ] | Room total $[ ]

The stage totals line earns its place twice. It lets the customer see where the money goes, and it lets you check that a stage has not quietly vanished from a room. The working order also doubles as the skeleton of your programme: plaster cannot start until first fix is signed off, so the block already tells you which trade waits for which.

Site notes the AI can actually use

A model writes only from what is in the prompt, so the notes decide the quality of the blocks. They do not need to be tidy. They need to be specific: measurements, conditions, what the customer asked for, and what you could not see. For each room, record these at the survey:

• Length, width and ceiling height, plus anything that breaks the shape (chimney breast, boxed stack, sloping ceiling).
• What is there now and what condition it is in: "tiles to 1.5 m, plaster behind unknown", "boards springy by the WC".
• Services you can see and where they appear to run, and where you cannot tell.
• Choices the customer has made, choices still open, and items they will supply themselves.
• Access, parking, working hours and anything that must stay in use (the only toilet, the kitchen).
• A numbered photo of every wall, the floor, the ceiling and each worry.

Here is how rough those notes can be. This is an illustrative set for one bathroom.

Bathroom first floor. 2.1 x 1.8, ceiling 2.4.
Old bath, basin, WC. Tiles to 1.5 m on 3 walls, plaster behind unknown.
Vinyl floor over boards. Boards bounce near WC and under bath. Can't see joists.
Customer wants walk-in shower where bath is, wall-hung basin, WC stays put.
Waste for shower is 1 m from existing stack. Cylinder is in airing cupboard next door, not touching it.
Customer picks tiles and sanitaryware, not chosen yet. Extractor fan wanted, nothing there now.
Hall carpet outside, customer wants it protected. Working 8 to 5, water off max 1 day.

Leave the customer's name, address and phone number out. The model needs room names and measurements, not identities. If you use a personal chat account, check its data controls before pasting job details; ChatGPT Business and Claude Team both state that business content is not used for training by default. Keep your prompt and rate sheet in a ChatGPT Project or a Claude Project so every quote starts from the same instructions.

The prompt that turns notes into a room block

The prompt does three jobs. It fixes the shape of the output, it stops the model inventing facts, and it turns every "unknown" in your notes into an allowance instead of a confident sentence. The rule against vague phrases matters most: models love "all necessary making good", which is exactly the sort of sentence that gets argued about.

You are drafting one room block of a renovation quote for a small building firm. Use only the facts in my survey notes. Do not invent quantities, brands, prices or dimensions. If a fact is missing, write TO CONFIRM in capitals instead of guessing.

Rules:
- Plain words. One meaning per sentence. Start each Included line with a verb.
- Use these headings in this order: STRIP-OUT, FIRST FIX, PLASTER, SECOND FIX, DECORATING, EXCLUDED, ALLOWANCES, ASSUMPTIONS, CUSTOMER DECISIONS, PROTECTION AND ACCESS. Skip a stage that does not apply.
- Anything I mark unknown or "can't see" becomes a provisional sum line with a placeholder for the figure and this settlement rule: "adjusted to actual labour at the labour rate in this quote plus materials at cost, with the customer's written approval before the work".
- Anything the customer will choose becomes a prime cost sum, supply only, with a decision date.
- Never write "all necessary", "everything required", "as needed" or "including all making good". Say exactly what is done and where it stops.
- Do not give prices unless I supply them.

SURVEY NOTES:
[paste the notes for one room]

Run it on the bathroom notes above and you get something like the block below. It is an illustrative output, trimmed for space, and it is a good first draft with four faults I would fix before it goes anywhere.

BATHROOM (2.1 m by 1.8 m, ceiling 2.4 m)
STRIP-OUT
- Remove bath, basin, WC, wall tiles to 1.5 m and vinyl floor covering.
- Cap off water and waste at the room boundary.
- Lift boards at the WC and bath positions to inspect joists (see PS-01).
- Load waste to the skip and sweep the room.
FIRST FIX
- Fit waste run to the walk-in shower position, 1 m from the existing stack.
- Move hot and cold supplies to the shower valve position: TO CONFIRM valve position.
- Fit waterproof tanking to the shower area.
- Run cable for the extractor fan: TO CONFIRM fan position.
PLASTER
- Board and skim the opened-up walls and the ceiling.
SECOND FIX
- Fit WC, wall-hung basin, taps and shower valve (supplied under PC-02).
- Fit extractor fan.
DECORATING
- Mist coat and two coats of emulsion to the ceiling and walls above tile height.
ALLOWANCES
- PC-01 Wall and floor tiles, supply only, allowance $[ ].
- PC-02 Sanitaryware, taps, shower valve, supply only, allowance $[ ].
- PS-01 Floor structure repairs if boards are found to be rotten, allowance $[ ].
CUSTOMER DECISIONS
- Tiles and sanitaryware chosen by [date], or the start date moves.
PROTECTION AND ACCESS
- Protect hall carpet with hardboard. Water off for one day maximum.

The faults are easy to spot once you know to look. "Waterproof tanking" is a scope item the model invented, because my notes never mentioned it: either I want it and add it to the notes, or it goes. "Cap off water and waste at the room boundary" assumed a boundary I never defined. The extractor fan appears at first fix and second fix, which is right in trade terms, but the cable and the unit should each carry one price in one place. And the block has no EXCLUDED section at all, so I would run a second pass for exclusions (covered below) rather than trust the silence.

The two TO CONFIRM flags are the prompt working as intended. Each one is a question for the customer or a decision for you, and neither should reach the printed quote unresolved. If a single bathroom is the whole job, the bathroom renovation scope of work tutorial goes line by line through that one room.

A four-room house, priced stage by stage

Say a four-person building firm is quoting a two-storey house: the kitchen, the first-floor bathroom, the hall with stairs and landing, and the back bedroom. Every figure below is invented to show the structure, so use your own rates. The customer sees the grid first, because it answers "where is the money going" before they read a single block.

The grid already tells a story. The hall costs more to decorate than the kitchen because of the stair walls and the access they need. Plaster is the second-largest stage because the hall is skimmed throughout (the plastering quote template covers skim, render and patch lines properly), and that is also where the quote needs a provisional sum, since nobody can tell whether the old stair-wall plaster is sound until it is tapped. Allowances sit in their own table, outside the grid, so they cannot hide inside a stage price.

The contract sum is the $33,850 grid total, plus $3,780 of prime cost sums, plus $2,750 of provisional sums: $40,380. Provisional sums are about 7% of that, prime cost sums about 9%. The split matters. The 9% is the customer's own choices, which they control. The 7% is genuine unknowns, and that is the figure to push down: for each one, ask what you could open up before quoting to price it properly.

The AI's part in all this is narrow. Run the room-block prompt four times, once per room, each with that room's notes. Keep your rates and totals in your own spreadsheet and paste them in as facts. Then paste the grid and the four blocks into one conversation and ask it to list any line that appears in two rooms and any stage that appears in the grid but has no lines in its block. A $20-a-month plan is plenty for this volume of text (ChatGPT Plus and Claude Pro both list at $20, with Claude Pro at $17 a month billed yearly). Plan on about ten minutes per room for drafting and an hour for the whole-quote check.

Provisional sums and prime cost sums in plain words

The two terms get mixed up constantly, and the mix-up is itself a source of arguments. This tutorial uses the working distinction below. Terminology differs from place to place, so put your own definitions in the quote rather than assuming the customer shares yours.

• A prime cost sum (PC sum) is an allowance for something the customer has not chosen yet, covering the supply of the item only: tiles, taps, internal doors. Fixing is priced elsewhere.
• A provisional sum (PS) is an allowance for work whose scope or cost you cannot fix at the survey, such as repairs under a floor you could not open. It covers labour and materials.

Customers care less about the label than about what happens to the number afterwards. Write the settlement rule once and reuse it on every sum. For PS-01 in the example, the allowance is $1,200 and the rule is: actual labour at the labour rate in this quote plus materials at cost, with written approval first. Here is how that plays out both ways, using a labour rate of $48 an hour.

• Under-run: two joists need doubling up. Nine hours is $432, timber $198, fixings $40, waste $110: $780 in all. The customer is credited $420 and the contract sum falls from $40,380 to $39,960.
• Over-run: six joists and a patch of subfloor. Twenty-one hours is $1,008, timber $420, fixings $60, waste $110: $1,598. The customer pays $398 more than the allowance and the contract sum rises to $40,778.

Nobody is surprised either way, because the rule and the approval step were in the quote before the boards came up. Loft conversions lean on provisional sums harder than any other job, and the loft conversion quote template shows how far to take the idea. The wording does the work, which is why it is worth having the AI rewrite every allowance into the same pattern: ID, item, what it covers, what it does not, figure, settlement rule, approval step.

Exclusions that settle arguments before they start

An exclusion only works if it names the thing. "Excludes anything not mentioned" convinces nobody and protects you from very little, because the customer never agreed to it and cannot tell what it covers. Name the items instead. Ask the model for a candidate list built from your stage grid, then cut what does not apply and add what you know about this particular house.

Here is the stage grid and the room blocks for this quote. List the exclusions this quote needs, one line each, with a one-line reason. Do not list anything already covered by an Included line. Flag any exclusion that contradicts an Included line. Do not add exclusions about things not present in this house.

These are the exclusions I would expect on most whole-house renovation quotes, with the reason each earns its place:

• Structural alterations, engineer's calculations and approvals, unless a line says otherwise. Otherwise a removed wall quietly becomes "part of the strip-out".
• Testing or removal of hazardous materials. If suspect material turns up, work stops in that area and the quote says so. You cannot price what you cannot identify, and you should not carry on regardless.
• Redecorating rooms not listed in the decorating lines. This one prevents the landing repaint request.
• Moving or storing customer furniture beyond what the protection line states.
• Items marked "by customer", including their delivery dates. A late worktop is the customer's delay, not yours, and the quote should say how the start date moves.
• Existing defects outside the working areas, recorded in the numbered survey photos. The survey pack doubles as your before-condition record.
• Out-of-hours and weekend working.
• Fees for parking permits or skip placement on public roads, where they apply.
• Supply and connection of appliances unless listed.

Compare the old and new wording side by side. Before: "Excludes anything not mentioned." After: "Excludes redecorating rooms not listed in the decorating lines; moving customer furniture out of the working room; supply and connection of appliances; structural alterations; testing or removal of hazardous materials; fees for parking or skip permits." The second version is longer, and every word of it can be pointed at in a conversation.

Have the AI argue against its own draft

Models are better critics than authors of their own work, provided you change the role. A second prompt, in a fresh chat so it has not seen your reasoning, asks the model to read the quote as a sceptical customer would: someone who wants the lowest total and reads every sentence for what they can claim is included.

Read this renovation quote as a sceptical homeowner who has been burned before. List every sentence that a reasonable person could read in two ways, every place where it is unclear who does the work, and every item you would expect to be included that is not mentioned anywhere. Quote the sentence, give the two readings and suggest a rewrite. Do not praise anything. Do not invent problems: if a sentence is clear, leave it out.

[paste the quote]

On the bathroom block from earlier, an illustrative run came back with these findings, and here is what I would do with each:

1. "Fit WC, wall-hung basin, taps and shower valve (supplied under PC-02)." Reading one: we supply them from the allowance. Reading two: the customer supplies them. Rewrite it as "supplied by us under PC-02, allowance $1,900, supply only". Accept.
2. "Board and skim the opened-up walls and the ceiling." "Opened-up" is undefined. Rewrite to name the three walls tiled to 1.5 m, plus the ceiling. Accept.
3. "Protect hall carpet with hardboard." How far? Rewrite from the stairhead to the bathroom door. Accept.
4. "Water off for one day maximum." Twenty-four hours, or a working day? Rewrite as no more than eight hours between 8:00 and 17:00 on one day, with 24 hours' notice. Accept.
5. "Mist coat and two coats of emulsion." No colour or finish stated. Ask the customer and add it to the decisions list.
6. "Load waste to the skip." Flagged as unclear about who provides the skip. Ignore: the strip-out line already includes skip hire, and the exclusions cover permit fees.

The critic also pointed out that nothing mentions waterproofing the shower area, which is the item the first draft invented. That is the useful kind of disagreement. Decide whether the job needs it and, if so, put it in your notes with a price, so the next draft includes it for a reason.

Changes after signing: one clause, one priced line

Room blocks make change easier to handle, because every change lands in a named room and a named stage. One short clause covers all of them. Let the AI tighten your wording, but keep the structure: written description, price, effect on the programme, approval before work.

VARIATIONS
Any change to the work described in this quote is a variation. Before we start a variation we will send a written description, the price (a fixed figure, or a rate and an estimate) and the effect on the programme. We carry out a variation only after you approve it in writing. Approved variations are added to the final invoice as separate lines, each naming the room and stage it belongs to.

The pricing mechanics of variations, including how small builders keep a running list, are covered in how small builders use AI to price variations and change orders. This tutorial only needs the clause, because the room blocks already say where each change belongs.

The pre-send pass: nine checks, mostly by hand

The model's output is a draft. These checks are the part that keeps your name safe, and every one of them takes a human:

1. Every dimension and quantity matches the survey notes and photos.
2. Totals are rebuilt in a spreadsheet. Do not trust a chat model's arithmetic, and do not paste its sums into the final document.
3. Every PC and PS has an ID, a figure and a settlement rule, and every ID mentioned in a block appears in the allowances table.
4. Every TO CONFIRM is gone.
5. Search the text for "all", "necessary", "as required", "etc." and "including" and replace each with named items.
6. Each stage in the grid has lines in its block, and each stage with lines has a figure in the grid.
7. No exclusion contradicts an Included line.
8. Customer decisions have dates and consequences.
9. Payment stages mirror the stage grid, which makes the builder invoice template for stage payments a natural next step.

Two mistakes show why the list is this long. In the first, the hall block said $7,580 while the grid said $7,850. The model had been given the figure in a sentence and swapped two digits; the grid was right. The customer noticed because they added up the room totals, and a $270 gap made them doubt every other number. In the second, a draft opened with "all necessary making good included". The customer read that as repainting wherever a wall had been touched, including the landing, which added roughly $1,150 of decorating that nobody had priced. The template now defines making good as filling and sanding to a paintable surface inside the areas the works disturb, and the decorating lines say which rooms are painted.

Keep a one-column log for a month. Write down every question a customer asks about what is included, every variation that needed a debate and every line the crew queried on site. Each entry points at a template line to tighten, and the aim is simple: the same question should not be asked twice.

Questions builders ask about room-by-room quotes

Should the quote show a price per room or one total?

Show both. Put the stage-by-room grid and the contract total on page one, because customers compare totals, then give each room its own block with a room total underneath. Room totals let the customer drop or defer a room without a re-quote, and they let you price any later change against the right block.

How many provisional sums are too many?

There is no fixed number, but each one should stand for work you genuinely could not see at the survey. If you can lift a floorboard, open a ceiling hatch or run a camera down a drain before quoting, do that instead of writing a sum. A customer who sees a dozen allowances is buying a guess, and may simply choose the quote that hides its own.

Can AI work out the prices for me?

It can draft wording and arrange a grid, but it does not know your day rates, your supplier prices or how long your crew takes. Give it your own rates and have it only arrange them, then add up the totals in a spreadsheet. Treat any price it produces without being asked as a guess to delete.

Do I need a lawyer to check the wording?

A quote is not a contract, but its wording often ends up inside one. Rules on written contracts, deposits and cancellation rights for home work differ widely, so have a qualified adviser review your standard terms, exclusions and variation clause once. After that the AI only fills in job facts, so you do not need a fresh review for every quote.

How long should one room block be?

Usually a page or less. If a block runs to two pages, the room is probably two jobs (say a bathroom and an en-suite) or the lines describe method instead of scope. Say what is done and where it stops. How your crew does it belongs in your site notes, not on the customer's quote.
