How Carrum Downs was built
From paddocks to estates
eMelbourne says Carrum Downs was mostly farmland until the 1980s, and its population grew from 2363 in 1981 to 13,051 in 1996.
Estate by estate
Botany Park dates from the late 1970s and early 1980s, the Botany Bush area became housing in the late 1990s, and new houses are still going up.
A village since 1945
The Brotherhood of St Laurence began building a community for older people here in 1945, later adding cottages and hostel accommodation. The first main residential area grew south of it.
On the old swamp
Most of the suburb sits on the former Carrum Swamp, which ran about 15 km north to south. Today there's heath and bushland, a flora and fauna reserve and a linear park along Boggy Creek.
Almost all houses
At the 2021 Census, 79.0% of occupied dwellings were separate houses and 19.6% semi-detached or townhouses. Flats were 0.4%.
Which job depends on when your house was built
Newer homes: start with the builder. From 1 July 2026, Victoria's Home Warranty insurance covers structural faults for 6 years and non-structural faults for 2 years on work over $20,000. Builders also owe implied warranties under the Domestic Building Contracts Act that can't be signed away. If a young roof leaks, raise it with the builder in writing before paying anyone else.
1980s and 1990s homes: ridges and tiles. A survey of Australian house styles notes that 1990s ranch-style homes usually have tiled roofs with wide eaves. The mortar under the ridge caps is normally the first thing to go. See roof restoration in Melbourne.
Concrete tile coatings. If your tiles are concrete, the colour fades over time. Monier says a repaint every five years or so keeps the look but doesn't improve waterproofing, so it's a cosmetic choice. Our restore or replace tool helps weigh it up.
Signs a re-coat offer isn't what it seems
- Someone knocks uninvited and wants a decision today. Consumer Affairs Victoria says roof re-coating has attracted some unethical operators.
- A deposit of more than 10%. Consumer Affairs suggests generally no more than that for a re-coat.
- No business name or street address you can check
- Work starting or money taken within 10 business days of an uninvited sale, which the law doesn't allow
If it were our place in Carrum Downs
We'd find the build date first. If the house is only a few years old, we'd go to the builder. If it's older, we'd have the ridges and any cracked tiles fixed and only pay for a re-coat if we wanted the colour back. And we'd never sign with someone who turned up at the door.
