One in four new Newcastle applications is for two homes on one block
Of 907 development applications to the City of Newcastle in hunternew's records since July, 228 were for a dual occupancy: two homes on one block.
That is one in four. Merewether leads, with 41. Wallsend, New Lambton and Lambton follow.
Where dual occupancies are being built in Newcastle
| Suburb | Applications |
|---|---|
| Merewether | 41 |
| Wallsend | 24 |
| New Lambton | 21 |
| Lambton | 18 |
| Maryland | 11 |
| Adamstown | 11 |
Two kinds of suburb lead. Merewether, where land is dear and a second home is worth a lot. And the west and north-west, such as Wallsend and Maryland, where blocks are big and cheap.
A typical Wallsend house sold for $887,444 in the year to June, on a block of 588 square metres. A typical Merewether house sold for $2.2 million on 506 square metres.
Why it matters: a quarter of new Newcastle applications are for two homes on one block, so this is now the main way the city adds homes.
Split and sell, or keep both?
182 of the 228 applications also asked to split the block into two lots, so each home can be sold on its own.
That is the usual small-developer play: build two, sell one or both, or keep one and sell the other.
What one costs to build in Newcastle
Owners and builders declared a typical building cost of about $930,000 for two homes, across 177 applications that gave a figure.
In Wallsend it was about $740,000. The middle half of all Newcastle applications fell between about $670,000 and $1.31 million.
That figure is the builder's estimate given to council. It leaves out the land, design, approvals, splitting the title and selling.
Could your block take one?
- The zone. Many Newcastle houses sit in a low-density residential (R2) zone, where two homes can be approved. The NSW Planning Portal's spatial viewer shows yours.
- The block's size and width. The Newcastle Local Environmental Plan and council's development plan set what is needed; near nominated centres the state minimum is 450 m² and 12 m wide.
- Flooding, slope and mine subsidence. Much of Newcastle sits over old mine workings, which can add a step.
- Heritage. Parts of the city are heritage areas with extra rules.
What happens to these applications?
Most get decided. Of the 228, 166 had been determined by mid-September, 17 were still being assessed, and 9 were waiting on more information.
35 were withdrawn or cancelled, often because the numbers or the design did not work out. Lodging is not building.
Newcastle suburbs with big blocks
A bigger block makes two homes easier to fit. These Newcastle suburbs have a typical house block of about 580 square metres or more and steady sales:
| Suburb | Typical block | Typical house |
|---|---|---|
| Tarro | 607 m² | $750,000 |
| Beresfield | 645 m² | $775,000 |
| Wallsend | 588 m² | $887,444 |
| Birmingham Gardens | 620 m² | $890,000 |
| Maryland | 630 m² | $920,000 |
| Elermore Vale | 651 m² | $926,500 |
Cheap land on a big block is where the sums are most likely to work, because the land is a smaller share of the total cost.
Sell one, keep one
A common plan: build two, sell one to pay down most of the build, and keep the other to live in or rent. It only works if the home you sell is worth enough to carry the plan.
Before committing, talk to council's planners about the block, and get a builder's quote for both homes.
Newcastle's dearest suburb
Merewether is Newcastle's dearest suburb with steady sales, with a typical house at $2.2 million in the year to June. It also has the most dual occupancy applications, 41.
That is not a coincidence. Where land is that dear, two new homes on one block can sell for far more than the old house, even after building costs close to a million dollars.
Our read: the cheap, big blocks of the west are where the sums most often work. Merewether works because the homes sell for so much.
Yes, but: lodging is not building: 35 of the 228 were withdrawn or cancelled.
What happens next: hunternew follows dual occupancy applications in Newcastle through the NSW Planning Portal's public register, including which ones are approved.
The bottom line: if you own a big block in the west, it is worth finding out what two homes would cost.
