Feasnap is a product in development for Independent Small-Scale Duplex and Townhouse Developers.
The problem
Independent Small-Scale Duplex and Townhouse Developers
For small-scale duplex and townhouse developers running the numbers themselves — where a 10% cost blowout can wipe out the entire profit on a 3-4 unit project.
- A typical small duplex nets a profit margin of under 10% — thin enough that a cost blowout, low valuation, delay or soft market can wipe it out entirely.
- It's easy to anchor on the cheapest builder quote you can find rather than the real cost, and only find out the gap once you're committed.
- Construction costs rose 5.9% in the year to June 2026, the fastest pace since 2023 — so a feasibility spreadsheet built on last year's numbers is already out of date.
In their own words
Real quotes from the people who have this problem
They know it costs $1.5 million to build, but they think, if I go to enough builders I'll find someone who's really keen...and I'll get it for $1.35 million.

Why now
What’s changed
- 01
NSW's low- and mid-rise housing reform made dual occupancies and semi-detached dwellings permissible across every R2 low-density zone statewide from 1 July 2024, opening around 188,000 previously-ineligible lots to small-scale duplex development. Mills Oakley ↗
- 02
House construction prices rose 5.9% in the year to June 2026, the fastest annual pace since the June 2023 quarter — a feasibility built on last year's cost benchmark is increasingly likely to be wrong. ABS Producer Price Indexes, June 2026 ↗
- 03
A typical small duplex already runs on an ~8.6% margin, so the rising cost of a feasibility mistake is colliding with costs that are moving faster than they have in three years. Riser ↗
The product
Feasnap
Feasnap is a guided feasibility check built specifically for 1-4 unit duplex and townhouse sites. Enter the site, land price and unit count, and it runs the full residual-land-value calculation against current regional construction costs and council contribution rates — flagging a thin margin, a low contingency or a stale comparable before you spend on plans, instead of leaving you to catch it yourself in a spreadsheet.
- 01
Enter the site address, land price, and the unit count you're considering — duplex, triplex, or up to four townhouses.
- 02
Feasnap runs the residual-land-value calculation against current regional construction cost and council contribution benchmarks, and flags anything that looks thin — a sub-10% margin, a contingency under 10%, or a stale comparable sale.
- 03
Download a report showing the numbers and the flags, so you go into a site — or a loan application — with the real picture, not a guess.
Market size
TAM, SAM and SOM
- TAMTotal market
- A$1.03M a yearAbout 11,570 duplex/townhouse projects a year (34,716 ABS-approved semi-detached/row/terrace/townhouse dwellings annually, assuming ~3 dwellings per project) × A$89 per feasibility check. ABS Building Approvals, Australia ↗
- SAMServiceable market
- A$773K a yearAbout 75% of those projects, assumed to be one-off or occasional builds rather than repeat professional developers who'd go straight to a full subscription platform — using the ~75% share of property investors who hold just a single property as a proxy for how many small developers are occasional, not professional. Property Update ↗
- SOMObtainable in 3 years
- A$15.5K a year2% of SAM — about 170 projects a year — within three years.
Sizes assume the working price of A$89 per feasibility check, which isn't validated yet. The 3-dwellings-per-project and 75%-occasional splits are assumptions, not measured figures, and the 2% share is an assumption, not a forecast.
Competition
What they use today, and where it falls short
| Today’s option | Scoped to 1-4 unit sites | Built-in sanity checks | No monthly commitment | Current regional cost data |
|---|---|---|---|---|
| Full feasibility platforms (subscription)Priced and built for an ongoing project portfolio (around A$149/month), overkill for someone checking a single site once. | Partly | Yes | No | Yes |
| Free or cheap static templatesStill a blank spreadsheet with no built-in sanity checks or current regional cost data — the same error risk this is about. | Partly | No | Yes | No |
| Hiring a quantity surveyor or consultantCosts more and takes longer than a self-serve check, and is usually engaged after a site is already under contract. | Partly | Yes | Yes | Yes |
| No check at all — gut feelThe riskiest option: margin and cost assumptions never get stress-tested before money is committed. | No | No | Yes | No |
| FFeasnapscoped to 1-4 unit duplex and townhouse sites specifically, with built-in sanity checks and current regional cost data, for a one-off fee instead of a subscription built for repeat developers. | Yes | Yes | Yes | Yes |
Business model
Pay-per-report, no subscription
Working price, not yet validated — priced as a fraction of a quantity surveyor's fee or a subscription platform's monthly cost.
A single Feasnap check costs a fraction of what a thin margin has at stake
Feasnap won't catch every risk a project faces; the comparison shows how little it costs relative to what's at stake. Riser ↗
