Why Some Development Sites Never Stack Up

Planning in 2026 is genuinely complex. With transport-oriented development (TOD) rezoning properties across the region, and councils like Inner West actively up-zoning large swathes of land to encourage more housing, there’s more opportunity than ever, but also more noise. More layers to cut through. More ways to misread a development site before you’ve spent a dollar. 

“Zoning is the beginning of the conversation, not the end of it.” 

The gap between concept and development approval 

Here’s what most people think: if a site is zoned correctly, the rest will follow. If it shows up in a TOD corridor, or it’s been flagged as LMR (low-medium residential), then it’s a goer. That’s a reasonable starting assumption, but it’s just that, a starting point. 

The reality is that two identical lots on the same street can have completely different development outcomes. One might yield six townhouses and strong margins. The other, because of slope, orientation, access width, a heritage overlay creeping in from the neighbouring property, or overshadowing constraints from an adjoining building might realistically only yield three, at a cost that makes the numbers tough. 

I’ve seen developers lose significant money not because they were careless, but because they moved too fast. The opportunity looked real. And it was, it just wasn’t as viable as they’d assumed. And by the time they found that out, the costs were already stacking up. 

6 planning and site constraints that don’t show up in the listing 

These are the things I want people thinking about before they go further. Not after. 

01 — Complies on paper, fails in reality: Zoning allows it. But council’s interpretation of setbacks, heights, and density often tells a different story on specific sites. 

02 — Access that kills yield: A site with a narrow frontage or awkward access can lose one or two dwellings before you’ve even drawn a floor plan. 

03 — Heritage creeping in: It doesn’t have to be on your property. A neighbouring heritage item can impose constraints you didn’t see coming. 

04 — Overshadowing and overlooking: Constraints that only become visible when you put a proper design on the site — and can fundamentally change what’s viable. 

05 — Services and infrastructure costs: Stormwater, sewer, power — the servicing reality of a site can add up fast and rarely appears in the listing. 

06 — Approval risk and timing: A site that looks straightforward can become a 12-month approval battle. That’s holding costs, stress, and lost opportunity. 

These are the everyday realities of development sites in this region. And every single one of them can be identified early. 

What early-stage development feasibility actually looks like 

Planning in 2026 is not a solo sport. The up-zoning activity happening across TOD corridors and LMR precincts means there’s genuine opportunity out there, but interpreting what that opportunity actually means for a specific site requires someone who lives and breathes planning controls day-to-day. Not someone who reads the zoning map once. 

A good planner who’s active in the current environment and across council interpretation patterns will tell you things about a site that no amount of time on the planning portal will surface. They’ll flag the approval risks. They’ll know where council is pushing back right now, and where they’re moving things through. That kind of intelligence is what separates a well-formed development strategy from an expensive assumption. 

Pair that with a builder’s eye on the same site, someone who can look at slope, access, servicing, and construction complexity and give you a realistic read on cost and buildability and you start to get a picture that actually reflects reality. 

That’s what a high-level feasibility review is designed to do. It’s a structured, early-stage conversation with the right expertise at the table to help you understand whether a development site is worth pursuing before you commit further time and money to finding out the hard way. 

Who this is actually for 

It’s for property owners who’ve got a site and want to understand whether it’s worth pursuing before spending more. It’s for developers eyeing up a subdivision, a roof space conversion, or an amalgamation opportunity in an up-zoned area. It’s for anyone looking at an LMR or TOD site who wants a clear-eyed answer on whether the numbers can work.
