En Bloc Potential: Identifying Properties with Collective Sale Prospects

En bloc potential depends on whether owners can agree on a sale that also makes commercial sense to a developer. An older building, a convenient location or an ambitious reserve price is only the starting point.

My approach is to assess the property as a home or rental investment first, then examine the collective sale opportunity. That keeps the decision grounded if a sale takes longer than expected or never happens.

Current collective sale rules and proposed 2026 changes

For a standard strata development, the current majority-consent requirement is measured by both share value and strata area. It is not simply a headcount. The Strata Titles Boards explains that age is determined by the latest Temporary Occupation Permit, or the Certificate of Statutory Completion if no TOP was issued. See the current STB guidance.

The proposal also raises the ordinary requisition threshold for forming a sale committee to 35%, shortens signature collection from 12 to six months, and extends the post-failure restriction period from two to three years. Heightened requisition requirements apply during that period; it is not an absolute ban on another attempt. The Bill also extends the regime to certain non-strata private residential developments whose flat owners do not own the underlying land. Source: MinLaw’s proposed amendments.

What about a sale already under way?

Do not assume a committee can switch thresholds immediately. The Bill contains transitional rules tied to commencement and the stage reached by an existing collective sale agreement. For qualifying developments at least 40 years old with signature collection still incomplete, it provides a route to terminate the old agreement and approve a new one, within specified conditions and a seven-month transition window. The sale lawyer should establish which provisions apply to the particular exercise. Read the Bill and transitional provisions.

How to assess a property’s en bloc potential

A useful assessment tests several conditions together. I would avoid describing any fixed age range as the ideal en bloc buying window.

1. Redevelopment capacity

Ask a qualified planning adviser to establish what could realistically be built. Compare the existing development with the applicable planning controls, then examine site access, shape, setbacks and other constraints. Apparent spare plot ratio is an investigation point, not a promise of approved floor area.

2. A price that supports the development budget

Work backwards from a realistic future project: achievable selling prices, construction, financing, professional fees, applicable taxes and land-related charges, plus a developer’s required margin. A site can be attractive while its reserve price leaves too little room for a viable bid.

3. Demand for the future homes

Evaluate the homes a developer would sell, rather than relying only on the existing estate’s address. Transport access, amenities, competing launches, likely unit sizes and the total purchase price all deserve attention. A prestigious district does not resolve an oversized acquisition budget.

4. Tenure and building condition

Separate building age from remaining lease tenure. An ageing building may bring maintenance concerns, while leasehold land raises different questions about the remaining term and the feasibility and cost of any extension. Request a site-specific assessment rather than assuming a lease top-up.

5. Owner alignment

Look beyond expressions of interest. Owners need to understand the reserve price, allocation of proceeds, likely costs and relocation implications. Different unit types and purchase histories can produce very different views of the same offer.

En bloc premiums: compare your own numbers

There is no reliable standard premium to plug into a buying decision. An average from a particular study would depend on its sample, period and comparison method. It would not establish what your unit will receive.

Start with the amount allocated to your unit under the proposed distribution method. Compare it with a supported estimate of the unit’s individual resale value at the same point in time, then examine your transaction expenses and next-home budget.

Keep cash available after completion separate from profit. Loan repayment and any required CPF refund affect how proceeds are available for your next purchase; they should not simply be labelled investment losses. Obtain a personalised completion statement and financing assessment.

Collective sale process and timing

Do not plan around a guaranteed 12–18 month finish. Separate the campaign, marketing, approval and completion stages.

1. Build the proposal. Form the committee and work through price, distribution and professional advice.
2. Obtain signatures. Under current guidance, the required consent must be reached within 12 months of the first signature.
3. Secure a purchaser and apply. STB guidance allows a further 12 months after the agreement reaches the required consent for finding a purchaser and applying to the Board.
4. Resolve approval and completion. The timetable depends on objections, the approval route and the sale contract.

Source: STB application guidance. These windows are procedural limits, not a promise that every campaign will use them fully or conclude successfully.

Consent alone does not guarantee approval. STB considers good faith, including price, distribution of proceeds and purchaser relationships. Where objections remain unresolved, applicants wishing to continue must seek High Court approval after a Stop Order. Read STB’s hearing guidance.

A practical checklist for owners and buyers

Weighing the pros and cons of participating

Beyond the numbers, joining a collective sale has real trade-offs worth weighing upfront:

• Potential upside: a higher payout than a regular resale, and no further burden of maintaining or upgrading an ageing building once the sale completes.
• The trade-off: the process can take years and depends on reaching collective agreement, so there is no guarantee of a timeline or even a successful outcome. Owners attached to their homes may find the prospect of demolition unsettling, and disagreement among owners is common and can cause delays or the attempt to fail altogether.

If you already own a unit

• Request your unit’s proposed allocation and a clear breakdown of estimated expenses.
• Compare the offer with current resale evidence and suitable replacement homes.
• Have the sale lawyer explain your agreement, deadlines and the effect of any future commencement provisions.
• Keep a workable housing plan if the attempt fails or takes longer.

If you are considering buying

• Underwrite the purchase using ordinary rental or own-use value.
• Budget for maintenance, vacancy and financing without assuming a collective sale date.
• Check the documented stage of any campaign; distinguish informal enthusiasm from signed consent and an actual buyer.
• Set a price you can justify even if the en bloc opportunity never materialises.
