Buying Into a Society That May Redevelop

What redevelopment means for an owner, the risks buyers underestimate, and the questions to ask before purchasing in an ageing building.

31 August 2026 · 2 min read

Ageing buildings in dense city areas are frequently discussed as redevelopment candidates. For a buyer, this changes the nature of the purchase entirely — you are not just buying a flat, you are buying a position in a process that may or may not happen.

Nothing here is legal advice; redevelopment rules, approvals and entitlements vary substantially by state and by society, and any specific transaction needs a lawyer who knows the local framework.

What redevelopment involves, broadly

The society appoints a developer, who demolishes the existing building and constructs a new one. Existing owners typically receive a flat in the new building — often larger than the original — and usually some form of accommodation or rent allowance during construction.

The developer's return comes from additional units sold in the new building.

Why buyers are attracted

  • The prospect of a larger, new flat for the price of an old one
  • Prime locations, since redevelopment candidates are usually in established central areas
  • A lower entry price, because the current building is old

The risks, in order of how often they bite

1. Timing. Redevelopment projects overrun routinely. A stated three-year timeline can extend well beyond it, and every extra year is a year of paying rent elsewhere.

2. The rent allowance stopping. Agreements specify a period. If the project overruns and the developer's finances deteriorate, the allowance is often the first thing to lapse — while the owner's own rent continues.

3. It never starting. Redevelopment requires a majority of members to agree, and disagreements between owners stall projects for years. Many "about to be redeveloped" societies have been about to be redeveloped for a decade.

4. Developer failure. Mid-project, with owners displaced and no building.

5. Entitlement disputes. What area each owner receives in the new building, and how it is calculated, is a common source of litigation.

The questions to ask before buying

  • Has the society formally resolved to redevelop, and by what margin?
  • Has a developer been appointed, and is there a signed agreement?
  • What does the agreement say about the timeline, the rent allowance, and penalties for delay?
  • What is the developer's completion record on comparable projects?
  • Are all approvals obtained, or "in process"?
  • Are there dissenting members, and is there any litigation?
  • What area entitlement would this specific flat receive?
  • Are any dues or contributions payable by owners?

Get the answers in writing from the society, not verbally from the seller.

If redevelopment is only a possibility, not a plan

Then price the flat as what it is today — an old flat in an old building — and treat any redevelopment upside as a possibility worth nothing at purchase.

Buyers who pay a premium today for a redevelopment that has not been agreed are paying for an outcome nobody controls.

What an agent should say

Plainly:

"If it happens, you may end up with a bigger new flat. If it happens late — which is common — you'll be paying rent somewhere else for longer than anyone told you. Buy it because the flat works for you today. Treat the redevelopment as a maybe."

That framing protects the buyer and protects you.

Frequently asked questions

Is buying in a society due for redevelopment a good idea?

It can be, and it carries substantial timing risk. Redevelopment can deliver a larger new flat, but the process routinely takes far longer than projected and owners live elsewhere throughout.

What is the biggest risk?

Delay. Owners typically vacate and receive a rent allowance for a stated period. When the project overruns, the allowance may stop while the rent obligation continues.
