Trendale Tower on Cairnhill Road has been launched for collective sale at a reserve of $168 million, its fourth attempt since 2018. The price has not moved much; the pitch has. Buyers are now being offered the option of redeveloping the site as a Serviced Apartment 2 (SA2) scheme rather than a conventional condominium.
That single line in the marketing is the most interesting thing about this tender. It is an admission that the strata-sale business case, tested three times, did not clear, and that the site may need a different use class to work.
What SA2 changes for a developer
SA2 is URA's long-stay serviced apartment category. It sits under residential use but carries a minimum-stay requirement, which puts it between a condominium and a hotel: no strata sell-down, but a recurring income stream from tenants who stay for months rather than nights. (Prospective bidders should verify the current minimum-stay period and the ABSD and remission treatment directly against URA's guidelines, as these have been revised since the category was introduced.)
The economics are structurally different from a condo. A strata developer needs an end-selling price high enough to cover land, construction, financing and the five-year Additional Buyer's Stamp Duty (ABSD) remission clock. An SA2 operator needs a yield on total development cost, and is not exposed to the same sell-by deadline. For a small prime-district site, that matters. The buyer pool for a 40-unit boutique condo in Cairnhill is narrow and the breakeven is high. The buyer pool for a serviced-apartment operator is different, and its willingness to pay is set by achievable room rates rather than by what the last new launch sold for per square foot.
Testing the $168 million
The question is whether $168 million clears on either basis. That depends on the land rate per square foot per plot ratio (psf ppr), which the tender documents will state and which has not been published in the reports of the launch.
The arithmetic is worth setting out so you can complete it when the numbers land. Take the $168 million reserve. Divide by the maximum permissible gross floor area, which is the site area multiplied by the permitted plot ratio. Add any development charge payable on the uplift in gross floor area, plus any lease top-up premium if applicable. That gives the all-in land rate.
As a stated assumption, not a confirmed figure: if the site yields 100,000 sq ft of permissible gross floor area and the development charge comes to $12 million, the implied rate is $180 million divided by 100,000, or $1,800 psf ppr. A condo developer would then need roughly $3,200 to $3,600 psf on the finished product to make that work with normal construction, financing and marketing costs. Whether Cairnhill supports that at scale is the whole argument. Substitute the real gross floor area from the tender documents and the same three steps give you the real answer.
The wider signal
The relaunch lands in a week of prime-market repositioning. Three freehold properties were launched at a combined $67 million, two of them flagged for boutique hotel conversion, with the tender closing 21 October. Separately, luxury units seized in the S$3 billion money laundering case failed to sell at auction, with the top bid on a two-bedroom-plus-study at Gramercy Park coming in at S$3.75 million.
Read together, the pattern is consistent: prime-district stock is being repriced by use, not by postcode. Hotel conversion, SA2, boutique residential, each carries a different breakeven, and sellers are increasingly marketing to whichever one gives the highest number.
If you own a unit in a small, older block in District 9 or 10, the practical lesson is that en bloc upside is no longer a function of land scarcity alone. It depends on whether the site works as something other than a condominium. And a reserve price that has survived four launches tells you about the appetite of buyers, not about the worth of your unit.
