Builders serving Southern River
None yet — tell us what you're building and we'll go and find one.
What building in Southern River actually involves
23 endorsed structure plans cover Southern River, planned for about 4,101 dwellings in 13.21 km². That is the densest concentration of separately-planned land of any suburb published on this site.
Twenty-three plans is twenty-three sets of rules
In a structure-plan area the lot layout, density and staging are fixed before any block reaches the market, so the plan — not the scheme map — decides what you can build. With this many of them in one suburb, a builder's experience under one plan does not transfer to the next, and "I've built in Southern River" is not the reassurance it sounds like. Ask which plan, and read it.
Staging decides when, not just what
A yield of about 4,101 dwellings is not delivered at once. The stage your block sits in determines when roads, power, water and sewer actually arrive, which on growth-front land is the difference between building next year and building in five.
R20 to R80
Four codes across a fourfold density range. The code sets the minimum and average lot size, the setbacks and the open space requirement.
Industrial and service commercial land alongside
An Industrial development zone and service commercial land are mapped within the suburb. Neither is residential and you cannot build a house on either — which is exactly why they matter: they govern what can happen next door.
What to ask a builder
Ask which structure plan covers the lot, which stage it is in, and when services are scheduled. Ask what sits on the land immediately adjoining.

How much development is planned in Southern River?
23 endorsed structure plans cover about 4,101 dwellings in 13.21 km² — the densest concentration of separately-planned land on this site.
Why does the structure plan matter more than the zone?
In a structure-plan area the plan fixes lot layout, density and staging before any block reaches the market. With 23 of them here, experience under one does not transfer to another.

R20 to R80 — a fourfold density range. The code sets the minimum and average lot size, the setbacks and the open space requirement.
Is there industrial land in Southern River?
Yes. An Industrial development zone and service commercial land are mapped in the suburb. Neither is residential, but both govern what can happen next door.
Is Southern River bushfire prone?
