Small housing sites have long been the engine room of SME development—flexible, deliverable, and relatively low risk.
That model has changed.
In today’s market, most small sites now require a full ‘planning ticket’ before they are even considered viable by developers. And even then, deals are far from guaranteed.
What’s Changed?
We’re seeing a consistent pattern across the South of England and beyond: sites that would have traded easily 2–3 years ago are now stalling.
The reasons are well understood:
- Interest rates remain elevated, impacting developer finance
- Build costs have softened slightly, but not enough to restore margins
- Sales rates are slower, with increased uncertainty on exit values
- Affordable housing values are under pressure
- Development costs continue to rise (BNG, Nutrient Neutrality, CIL, S106, SPA)
- Planning outcomes remain inconsistent and difficult to de-risk
Individually, none of these are fatal. Combined, they are stopping schemes from stacking.
The Shift in Risk
The key change is where the risk now sits.
Developers—particularly SMEs—are no longer willing to absorb significant planning and viability risk upfront. The result:
- Unconsented sites are often overlooked entirely
- Bids are more cautious, with greater emphasis on margin protection
- Fewer buyers are competing for each opportunity
At the same time, many landowners are still anchored to historic pricing expectations.
That gap is where deals are falling apart.
Why Pricing Matters More Than Ever
In this market, pricing is the primary lever to unlock a sale.
A site priced on outdated assumptions—when:
- finance was cheaper
- planning was more predictable
- and margins were easier to achieve
…will simply not transact today.
By contrast, a site that reflects:
- current build and finance costs
- realistic sales values
- and the true level of planning risk
will generate interest and competitive tension.
The reality is straightforward:
the market hasn’t disappeared—pricing has just not caught up with it.
Planning Isn’t a Silver Bullet
Securing planning consent was once the key milestone to unlock value.
Now, even consented sites can struggle if:
- obligations are too high
- density is constrained
- or margins are too tight
Planning reduces risk—but it doesn’t eliminate viability challenges.
What This Means for Landowners
For landowners considering a sale, the approach needs to evolve:
- Be realistic on value – the market has reset
- Consider planning strategy carefully – consent may be necessary, but it comes with cost and risk
- Take advice early – positioning and timing are critical
Most importantly, understand that today’s buyers are disciplined. They are not chasing sites—they are selecting them.
The Bigger Picture
Small sites should be the easiest homes to deliver.
Instead, they are increasingly some of the hardest to bring forward.
If SMEs are to play a meaningful role in housing delivery, the system needs to:
- reduce upfront risk
- provide greater planning certainty
- and rebalance the burden of contributions
Until then, correct pricing remains the difference between a site that sells and one that sits still.
