About Box Hill
Building in Box Hill.
Box Hill is one of Sydney's fastest-growing release areas, with narrow 8.5–10m frontages typical of the new estates. Belford 23, Coastal 23 and Double Story 05 are our bread-and-butter here — designs built specifically for compact-frontage blocks without sacrificing room count.
The Hills LGA
Postcode 2765
Box Hill was farmland until it was rezoned for housing as part of the North West Growth Area. Today it is mostly new estates, with buyers purchasing a registered lot and then choosing a builder — which is where we usually come in.
Buying land and building separately gives more control over the design than a project-home package, but it also means checking more yourself: the lot’s fall, the soil, easements and the estate’s design guidelines all affect the price of the house.
Building on a new Box Hill lot
Box Hill has a rolling landscape, so many lots have a noticeable fall. Some developers deliver lots already benched with retaining walls; others leave the slope for the builder. Which one you have changes the slab design and the site cost.
Newly filled land also needs care. A geotechnical report confirms the site classification under AS 2870, which sets how stiff the slab and how deep the piers need to be. We get this before fixing the contract price, so it doesn’t become a variation later.
Planning in Box Hill
Box Hill sits within The Hills Shire Council area, but as a growth-area precinct some of its planning controls come from state precinct planning rather than only the local LEP. Estate design guidelines usually add another layer on top.
New homes on standard estate lots often qualify for complying development. Your contract of sale, the estate guidelines and the planning certificate together tell us what can be approved and how quickly.
Authoritative planning sources
Controls vary by lot and can change. Confirm the current zoning, overlays and approval pathway for the property before relying on general guidance.

Common questions
Building in Box Hill: common questions.
My Box Hill lot slopes — will that cost more?+
Usually yes, through extra excavation, retaining walls, drainage or a stepped slab. We price the site works separately so you can see exactly what the slope adds before you commit.
What is a site classification and why does it matter in Box Hill?+
AS 2870 classifies sites by how much the soil moves. Filled or clay-heavy land on new estates can have a higher classification, which means a stiffer slab or deeper piers. A soil test before contract avoids surprises.
Do estate guidelines apply on top of council rules?+
Yes. Most Box Hill estates have design guidelines covering facades, materials, fencing and driveways. The developer may need to approve your plans before the certifier does.
Is Box Hill part of the North West Growth Area?+
Yes. It was rezoned for housing as a growth precinct, so some controls come from state precinct planning as well as The Hills Shire Council.
