Changi South: Plot Ratio 1.0, 0.64 Built

What a six-year rent run does and does not say about yield, holding costs and exit.

Published

A plot ratio of 1.0 on 77,237 sq ft of land, set against a building that uses about 0.64 of it: that pairing is at the centre of a Changi South offer reported by EdgeProp on 6 October 2026. The property, 29 Changi South Street 1, is a Business 2 site on a JTC lease with roughly 30 years remaining, put out by expression of interest (EOI) at an indicative $12.8 million, according to EdgeProp. Business 2 is the zoning category for general industrial activity, and a JTC lease means the land is held under a lease from JTC, so the remaining term forms part of the offer.

KeyStone @ Mandai Readers and the Plot Ratio Gap

EdgeProp described the land as regular in shape and the existing structure as a two-storey factory-cum-warehouse of about 49,693 sq ft. Plot ratio is total floor area divided by land area. Applying the stated plot ratio of 1.0 to the land area gives about 77,237 sq ft of floor area, roughly 27,544 sq ft above what stands on the plot. Both results are calculations from EdgeProp's figures, not numbers the outlet published, and they describe zoning rather than any plan for the site.

The marketing agent, as relayed by EdgeProp, calls the layout practical for redevelopment into a new facility. EdgeProp reports no proposal beyond that remark, so the plot-ratio gap is the only measure of scale the report offers.

How the EOI Reaches KeyStone @ Mandai Followers

An EOI is a call for offers by a stated deadline: interested parties submit a proposal, and the seller reviews what arrives once the window closes. The word indicative marks the $12.8 million as a guide for those offers and not a fixed price. EdgeProp reported that this one closes at 3 pm on 13 November 2026 and that the property comes with vacant possession. For readers who follow industrial supply, the EOI is the dated step, with 13 November as its marker. The notice concerns manufacturers, logistics operators and owner-users in search of a site that already carries a building.

EdgeProp quotes no rent, yield or return for the site, so none are drawn here. The indicative $12.8 million is a seller's reference point, and EdgeProp labels it indicative.

Supply Signals Around KeyStone @ Mandai

On context, EdgeProp cites access to Changi Airport and to Singapore's logistics and manufacturing ecosystem. It notes that the ongoing Changi East development, described as the airport's largest expansion to date, should strengthen the area's role as a logistics hub. For a reader tracking supply, the notice is one data point: a two-storey building on a plot whose zoning allows more floor area, offered by EOI.
