Trendale Tower’s S$168m relaunch hinges on a new rental route

Trendale Tower at 79 Cairnhill Road has returned to the collective-sale market with a S$168 million guide price. The public tender opened on 16 September 2026 and is scheduled to close at 3pm on 23 October 2026.

For owners and prospective Cairnhill buyers, the main question is whether this signals stronger land values. Not yet. The asking price is unchanged from the development’s December 2022 attempt; the meaningful change is a possible long-stay serviced-apartment use that could attract buyers beyond conventional condominium developers.

That added route could improve the site’s appeal, but it remains subject to planning approval and significant ownership and operating constraints. Trendale Tower now presents a broader development proposition—not evidence of a completed sale or a general repricing of Cairnhill homes.

The guide price has not moved since 2022

Trendale Tower is a 20-storey freehold development comprising 18 apartments on a reported 21,709 sq ft site. It is marketed as a residential-zoned District 9 property with a gross plot ratio of 2.8.

The S$168 million price is notable precisely because it is not new. Trendale Tower was offered at about S$163.5 million in 2018, relaunched at S$178 million in August 2022 and marketed again at S$168 million in December that year. The 2022 collective-sale market was already confronting a gap between owners’ expectations and developers’ assessments of costs and risk.

Holding the price rather than raising it suggests that the owners are trying to strengthen the proposition through permissible use, rather than asserting that the underlying land has appreciated sharply. That distinction matters to neighbouring owners: a guide price is a seller’s target, not transactional evidence.

It also matters to buyers comparing nearby homes. A collective-sale site is valued as a development or operating asset, while an individual condominium is priced according to its tenure, age, condition, floor, outlook and buyer demand. One cannot serve as a direct substitute for the other.

The new argument is long-stay rental optionality

The relaunch is being marketed with the possibility of a Serviced Apartment II, or SA2, development. Planning support has reportedly been indicated in principle, but any scheme remains subject to an outline application, detailed approval and regulatory compliance.

URA’s rules make SA2 fundamentally different from an ordinary condominium. An SA2 development must remain under single ownership, cannot be strata-subdivided and must be professionally managed. Occupants must stay for at least three months.

Those conditions widen the possible use of the land but narrow the type of buyer capable of pursuing it. A conventional residential developer generally expects to recover land, construction, financing and marketing costs by selling individual units. An SA2 owner instead has to fund and retain an entire building, secure tenants and manage occupancy and operating costs over time.

That structure may suit an owner-operator or long-term private investor seeking a rental asset near Orchard Road and the central area. It will not necessarily suit a developer whose capital model depends on strata sales and faster recycling of funds.

“The relaunch widens the use case; it does not remove the need for a buyer to make the numbers work.”

The strongest case for the relaunch is therefore not that SA2 guarantees a higher value. It is that an additional, legally recognised use may bring a different class of bidder to the table.

Planning potential is not planning permission

Owners should distinguish three stages that can easily blur in collective-sale marketing: an indicated planning possibility, an approved scheme and an economically viable project.

URA permits applicants to use an Outline Application to obtain broad guidance on matters such as land use, gross plot ratio and building height. SA2 proposals may be considered on residential sites with suitable road frontage or within mixed-use areas, but every proposal remains subject to planning assessment.

The available reporting does not establish a final redevelopment envelope, approved room count or completed SA2 application for Trendale Tower. Nor does it identify a purchaser committed to operating the property this way.

This uncertainty does not make the option meaningless. Early planning feedback can help a bidder decide whether further design and due diligence are worthwhile. But owners should not treat support in principle as equivalent to permission that automatically produces a profitable development.

For prospective Cairnhill homebuyers, the distinction is equally important. A future SA2 building would have a different occupier profile and exit route from a strata condominium. Its relevance to surrounding resale values would depend on what is eventually approved and built—not simply on its inclusion in the sale pitch.

The reported land-rate arithmetic needs clarification

The marketing reports an indicative rate of about S$2,248 per sq ft per plot ratio, after accounting for a 7% balcony bonus. A simple calculation using only the other published figures produces a different result.

Multiplying the reported 21,709 sq ft site by the 2.8 plot ratio gives approximately 60,785 sq ft of gross floor area. Applying a 7% uplift produces about 65,040 sq ft. Dividing S$168 million by that area gives roughly S$2,583 psf ppr.

The difference is approximately S$335 psf ppr, or 13% of the simple calculated rate. This is mastREplan’s calculation from the reported inputs, not a substitute for the collective-sale documents.

A larger permissible floor-area basis, another planning assumption or different treatment of bonus space may explain the gap. Until the exact denominator is disclosed, the S$2,248 figure should be treated as a marketing calculation rather than an independently verified land rate.

This is not a technical footnote. A bidder’s effective land cost influences the room available for construction, finance, professional fees, operating returns and contingency. Differences in assumed buildable area can materially alter whether a proposal clears an investment committee.

What owners and buyers should watch next

A tender submission would still not mean that every Trendale Tower owner has completed a sale. For developments at least 10 years old, Singapore’s collective-sale process generally requires consent from owners holding at least 80% of both share value and strata area. Statutory procedures also allow non-consenting subsidiary proprietors to raise objections.

Owners’ practical outcomes would depend on matters not established by the headline price: the collective-sale agreement, apportionment method, conditions attached to an accepted offer and eventual completion arrangements. No reliable per-owner proceeds can be derived merely by dividing S$168 million by 18, because apartment interests and distribution terms may differ.

The counterargument is that a scarce freehold parcel in Cairnhill deserves patience. Its central location and the possibility of holding an entire long-stay rental building could be difficult to replicate. Yet the unsuccessful earlier attempts show that scarcity alone has not closed the gap between owners’ expectations and buyers’ feasible economics.

The scheduled 23 October 2026 tender close is consequently the useful event to watch. A credible bid—and its conditions—would reveal more about demand for whole-building rental optionality in Cairnhill than the unchanged S$168 million guide price does today.

An unrelated location entry retained in the frozen evidence ledger supplies no evidence about Trendale Tower and has not been used to infer its characteristics or value.
