Builders get knockdown rebuild clients mostly from homeowners already near their work: the Association of Professional Builders recommends knocking on 30 doors around every active project (10 left, 10 right, 10 across). Add reactivated past enquiries and agent referrals, then gate every lead with four questions before a site visit.
The short answer from LeadsNow AI: Knockdown rebuild clients already own their block, so the best sources are the streets around your active sites, your old quotes and the agents who appraise ageing houses, not broad portals. LeadsNow recommends scoring each source on land, overlays, budget including demolition and finance stage, and only booking a site visit when an enquiry passes three of four.

Where do knockdown rebuild clients come from?
Knockdown rebuild clients come from five sources: neighbours of your active sites, past enquiries that never signed, real estate agents and valuers, display homes and lead portals. They differ in one way that matters more than volume: a knockdown rebuild client must already own the land, and the block must allow the house they want.
- What the client already has: a block, an old house on it and a reason to stay in the suburb.
- What can stop the job: title, zoning and overlays (heritage, flood, bushfire), demolition and asbestos costs, and construction finance.
- What you are up against: volume builders with dedicated knockdown rebuild teams, such as Metricon, which promotes “no stamp duty” as a reason to rebuild rather than move.
- The asset on this page: the Knockdown Rebuild Lead Source Scorecard, a four-question site-visit gate and a worked example of site visits per source.
Rules of thumb
- Knock on 30 doors around every active site: 10 to the left, 10 to the right and 10 across the street (the APB 10x10x10 strategy).
- No land on title, no site visit: ownership is the one gate a knockdown rebuild cannot work around.
- Ask the build year on the first call: homes built or renovated before 1990 might contain asbestos (ASSEA).
- Judge every source on site visits per enquiry: in the worked example below, past enquiries convert 60% to a visit and portals 15%.
- In NSW, budget the sales timeline for five clear business days of cooling-off after the client is given a copy of a large job contract (NSW Fair Trading).
How it works
How a builder turns knockdown rebuild interest into a site visit
Knock 30 doors per site
Introduce yourself to 10 neighbours left, right and across from each active build. Offer a direct contact and the street’s zoning facts.
Reactivate unsigned quotes
Contact knockdown rebuild enquiries from the last 24 months on a trigger, with consent. They already own the block and saw a price.
Run the four-question gate
Ask about land, overlays, budget including demolition, and finance stage. Three yes answers, including land, earn a visit.
Book the site visit
Book qualified enquiries for a site visit with the missing item on the agenda. Send the rest a dated call back.

Knockdown rebuild clients: FAQ
Is a knockdown rebuild letterbox drop covered by the Spam Act?
A paper flyer is not an electronic message, but any follow-up by email or SMS is. The ACMA says you must have consent before sending marketing emails or messages, identify yourself as the sender and make it easy to unsubscribe. Ask the neighbour for permission face to face and record who gave it, when and how.
What contract does a knockdown rebuild need in NSW?
A knockdown rebuild is far above the $20,000 line, so in NSW it needs a large job contract. NSW Fair Trading lists what that contract must contain, including a cooling-off period of five clear business days and an insurance certificate under the Home Building Compensation scheme. Other states have their own rules, so check your state regulator.
Should a builder check council overlays before a knockdown rebuild site visit?
Yes, because an overlay such as heritage, flood or bushfire can change what the client is allowed to build before you have spent two hours on site. Volume builders put this first too: Metricon lists site assessment, a soil test and confirming zoning rules and overlays as step one of its knockdown rebuild process.
Does an older house change a knockdown rebuild budget?
Often, yes. The Asbestos and Silica Safety and Eradication Agency says a home built or renovated before 1990 might contain asbestos, and that asbestos was phased out by 1990 and banned in 2003. Ask the build year on the first call so the client’s budget includes testing and licensed removal, not only demolition.
Are lead portals worth it for knockdown rebuild builders?
We could not find a public Australian benchmark for portal lead quality on knockdown rebuilds. In this page’s worked example, portals supply 44% of enquiries but only 24% of site visits, so test one for a set period and judge it on site visits per enquiry, not on enquiry count.
The Knockdown Rebuild Lead Source Scorecard
The Knockdown Rebuild Lead Source Scorecard scores five lead sources from 0 to 2 on four site-visit signals, for a total out of 8. Each signal decides whether two hours on site can lead to a contract. The scores are our assumptions from how each source arrives, not measured rates: replace them with what your own enquiry records show.
| Lead source | Land owned | Council and overlay check | Budget includes demolition | Finance stage known | Score out of 8 |
|---|---|---|---|---|---|
| Active-site neighbour drop | 1 (some neighbours rent) | 2 (same street controls you already checked) | 1 (they watched next door) | 0 | 4 |
| Past enquiry reactivation | 2 | 1 (if you assessed the site before) | 2 (they saw your quote) | 1 | 6 |
| Agent and valuer referrals | 2 (the agent appraised their house) | 0 | 0 | 1 | 3 |
| Display home visitors | 1 (mixed with land buyers) | 0 | 1 | 1 | 3 |
| Lead portals | 1 | 0 | 0 | 0 | 1 |
The neighbour drop scores 2 on overlays for a reason most builders miss: a house in the same street sits under the same zoning, and you have already checked those controls for the job you are building. That makes the first conversation with a neighbour concrete, because you can tell them what the street allows.

The four-question knockdown rebuild site-visit gate
The knockdown rebuild site-visit gate is four questions asked on the first call, and an enquiry needs three “yes” answers, including the first, before you book a site visit. Each question maps to one column of the scorecard.
- Land: “Is the block in your name, and do you live in it now?” A “no” ends the knockdown rebuild conversation; it may still be a house-and-land lead.
- Overlays: “Has anyone checked your zoning and overlays?” A “no” is fine if you run the desktop check yourself before the visit.
- Budget: “Does your budget include demolition, site costs and somewhere to live during the build?” Ask the build year here, because a pre-1990 house adds asbestos testing and removal.
- Finance: “Are you paying cash, have you spoken to a lender or broker about a construction loan, or not yet?” Record the answer; never advise on it.
Four “yes” answers earn a site visit this week with whoever prices the job. Three earn a site visit with the missing item on the agenda. Two earn a desktop overlay check and a dated call back in 30 days, and fewer go to your newsletter list. The custom home builder enquiry gates use timeline instead of overlays; a knockdown rebuild swaps it because the block, not the start date, is what kills the job.
How many site visits does each knockdown rebuild lead source produce?
A builder running all five knockdown rebuild sources gets about 34 enquiries and 9.45 qualified site visits a month at the mid-band assumptions below. Portals supply 44% of those enquiries but 24% of the visits. Every input is an assumption, labelled, for you to replace.
| Lead source | Monthly input (assumed) | Enquiries a month | Gate pass rate (low / mid / high, assumed) | Site visits (low / mid / high) |
|---|---|---|---|---|
| Active-site neighbour drop | 2 active sites x 30 doors = 60 doors, 2% enquire | 1.2 | 30% / 50% / 70% | 0.36 / 0.6 / 0.84 |
| Past enquiry reactivation | 25 old enquiries contacted, 12% reply | 3 | 40% / 60% / 80% | 1.2 / 1.8 / 2.4 |
| Agent and valuer referrals | 3 referrals | 3 | 25% / 40% / 55% | 0.75 / 1.2 / 1.65 |
| Display home visitors | 12 groups asking about knockdown rebuild | 12 | 20% / 30% / 45% | 2.4 / 3.6 / 5.4 |
| Lead portals | 15 leads | 15 | 10% / 15% / 25% | 1.5 / 2.25 / 3.75 |
| Total | 34.2 | 6.21 / 9.45 / 14.04 |
At an assumed 25% site-visit-to-contract rate, those totals become about 1.55, 2.36 or 3.51 signed knockdown rebuilds a month. Two things fall out of the arithmetic. Portal leads cost you 15 gate calls for 2.25 visits, while 25 reactivation contacts cost 3 gate calls for 1.8 visits. And the neighbour drop looks small at 0.6 visits, but it costs nothing except time on streets you already drive to. To size the whole pipeline backwards from the builds you want, use the builder reverse funnel calculator.

How to run the active-site neighbour drop
The active-site neighbour drop is the 10x10x10 method: the Association of Professional Builders describes it as tried and tested for builders who specialise in knockdown rebuilds or renovations. You introduce yourself as the builder working nearby and give the neighbour a direct contact for noise or blocked driveways.
The APB article frames it as being “a considerate neighbor, not a pushy salesperson”, so the knock is about the current job first. Projul, a construction management software company, suggests the same move with a flyer or door hanger near visible projects. For a knockdown rebuild builder, add three things the flyer can say that a generic builder cannot: the street’s zoning and the overlays you already checked, the demolition date, and an offer to show the finished house to anyone thinking about rebuilding. Ask permission face to face before you follow up by email or SMS, and note it.
Reactivating old knockdown rebuild enquiries
Old knockdown rebuild enquiries are the highest-scoring source on the scorecard, at 6 of 8, because the client already owns the block and has seen a price that includes demolition. Pull every enquiry from the last 24 months that got a quote or a site visit and never signed, and contact them on a trigger: a rate change, a new design or a finished build in their suburb.
Under the Spam Act 2003, the ACMA says you may infer consent in some circumstances, such as when a person has a provable, ongoing relationship with your business and the marketing is directly related to it; otherwise get express consent first. The method is set out on the database reactivation page.
What does running knockdown rebuild lead generation yourself cost?
Running the five knockdown rebuild sources yourself costs about 35 hours a month at the mid-band example above, before any advertising spend. The hours below are assumptions: 3 minutes a door, 10 minutes a reactivation contact, 15 minutes a gate call and 2 hours per site visit including travel.
- Neighbour drop: 60 doors at 3 minutes is 3 hours.
- Reactivation: 25 contacts at 10 minutes is about 4 hours.
- Gate calls: 34.2 enquiries at 15 minutes is about 8.5 hours.
- Site visits: 9.45 visits at 2 hours is about 19 hours.
The site visits are the part only the builder can do. The gate calls, reactivation contacts and follow-up are the parts that slip when you are on site, and they are the reason the 34.2 enquiries do not become 9.45 visits. Display home follow-up has its own clock, covered in how to convert display home visitors, and the wider channel mix for builders is on the builder lead generation page.
