Home Renovation Brief is a Claude AI skill — scope, material specs, trade sequencing, and permit flags in one contractor-ready document.
A contractor walks into your kitchen for the first time. You've prepared. You spent an evening with Claude writing up your renovation plans — the open-plan layout, the bifold doors, the new kitchen island, the downstairs bathroom. It reads beautifully. You hand it over. The contractor reads it in about forty-five seconds and says, "Right. So what are the structural drawings showing for that wall removal?"
There are no structural drawings. You didn't know you needed structural drawings at this stage. And now the meeting that was supposed to end with a quote has turned into a lesson in what a contractor actually needs before they can price anything. You'll go back, get the engineer involved, and try again in three weeks — if the contractor is still available.
This isn't bad luck. It's the gap between a renovation description — which is what generic AI produces — and a renovation brief, which is what contractors use to plan and price work. That gap has a cost, and it's usually measured in delays, variation orders, and the uncomfortable discovery that two contractors quoted very different things because they made very different assumptions about scope.
Four Places Generic AI Output Breaks Down
Generic AI is genuinely useful for many writing tasks. For renovation planning, it runs into four specific failures — not because it writes badly, but because it doesn't know what a contractor actually needs to read.
Generic AI writes for a reader who wants to understand the vision. A brief is written for a reader who needs to price, plan, and execute the work. These are not the same document — and the confusion between them is where renovation projects go wrong before they start.
That gap is exactly what the Home Renovation Brief skill for Claude was built to close.
What the Contractor Is Actually Reading For
When a contractor reviews a brief, they're answering four questions in sequence: What am I being asked to do? What are the structural or service constraints I need to account for? Which trades are involved and in what order? And can I price this accurately against a defined scope, or am I guessing?
A generic AI output typically answers none of these cleanly. The scope is implied rather than defined. The structural constraints aren't surfaced. The trade sequence doesn't exist. And because the material specifications are aesthetic rather than technical, the contractor is essentially creating their own brief from your vision statement and pricing against their interpretation.
When three contractors quote the same project and the numbers are £30,000 apart, the usual explanation isn't incompetence — it's that they were quoting three different briefs they each invented from the same vague document.
A well-structured brief fixes this. Not because it removes all ambiguity — experienced contractors will always have clarifying questions — but because it eliminates the structural ambiguity that produces wildly different quotes and the surprise variation orders that appear three weeks in.
What a Contractor-Ready Brief Contains
The difference between a renovation description and a renovation brief is structural, not stylistic. Here's what each section needs to contain for a contractor to actually use it.
| Document element | Generic AI output | Contractor-ready brief |
|---|---|---|
| Scope definition | Describes desired end result ("open plan kitchen/diner") | Lists works in scope line by line; explicitly names exclusions |
| Material specification | Aesthetic reference ("timber flooring," "bifold doors") | Technical spec: product type, grade, finish, subfloor requirement, supply-and-fit or supply-only split |
| Trade sequencing | Not present | Named trade order with dependencies flagged (e.g. first fix M&E before plastering, screed before tiling) |
| Structural flags | Not present | Load-bearing elements identified; SE sign-off requirements noted as action items |
| Permit requirements | Not present | Likely planning and building regulations requirements identified by project type |
| Budget framework | Single budget figure | Line-item breakdown by trade and material category with contingency guidance |
The Home Renovation Brief skill produces this document — not from a template, but from research calibrated to your specific project type. A loft conversion brief has different structural considerations than a kitchen extension. A period property flags different items than a 1990s new-build. The skill researches what your project type actually requires before it writes a word.
Side by Side: The Same Project, Two Documents
Same homeowner. Same renovation. Same information provided. Here's what generic AI produces versus what a calibrated skill produces — and why the difference matters the moment it reaches a contractor.
We are planning a ground floor extension to create an open plan living and kitchen space. The project will include removal of the wall between the existing kitchen and living room, a rear extension of approximately 4 metres, and new bifold doors to the garden. We would like underfloor heating, a new kitchen, and a downstairs WC added near the existing utility room.
The overall aesthetic should be contemporary and light. We have a budget of around £90,000 and would like to complete the project within six months if possible.
Rear single-storey extension (~4m × 4.5m GIA). Removal of load-bearing wall between kitchen and sitting room. Ground floor WC addition (internal, near utility). New kitchen supply-and-fit. UFH to extension slab only.
Excluded: Existing sitting room decoration, garden landscaping, appliances (client supply), external lighting.
Structural pre-requisites: SE calculation required for load-bearing wall removal and steel specification. Party wall notice required (shared boundary, east elevation).
Permit flags: Rear extension likely exceeds PD limits — planning application required. Building regs required for structural works, new drainage run (WC), and glazing spec.
Trade sequence: Groundworks → structure + roof → weathertight → first fix M&E + UFH pipework → insulation + screed (28-day cure) → wall removal + steel → second fix → kitchen fit → WC fit-out → decoration → snagging.
Material specs (for quoting): Bifold system — thermally broken aluminium, triple glazed, client-specified RAL. UFH — water-fed, manifold to existing boiler, thermostat per zone. Kitchen — supply-and-fit, client-specified units, solid surface worktop.
The generic version gives a contractor a conversation starter. The skill version gives them a document they can quote against. The structural pre-requisites section alone — flagging the need for a structural engineer's calculation and a party wall notice — represents work that must happen before a builder can mobilise. Knowing that upfront means you initiate those processes now rather than discovering them as a delay after work was supposed to start.
Who Actually Needs This
Homeowners approaching their first significant renovation. Anyone who has received wildly different quotes for the same project and couldn't understand why. Property developers who need a consistent brief format to tender multiple projects against comparable contractors.
The skill is most valuable in the window between "we know what we want to do" and "we're talking to contractors." That preparation window is where most homeowners lose weeks — going back and forth with contractors who are trying to extract the information that should have been in the brief. A well-structured brief cuts that process and gives you better quality conversations because the contractor arrives having read something they can actually work with.
The brief isn't the least interesting part of a renovation. It's the part that determines whether everything else goes well. What you hand a contractor on day one sets the terms of the entire project — what gets done, what gets excluded, what gets discovered mid-build and called a variation. Getting that document right before anyone picks up a tool is worth more than any decision you'll make about tile colour or worktop material. The vision is easy. The document that executes it is the hard part.
The next piece most people tackle from here is listing copy that sells the lifestyle, not just the specs.
