At least 60% of each strata unit must be used for industrial purposes, so up to 40% can be ancillary office. What that means for a GATE+ buyer.
At least 60% of the floor area of your unit must be used for industrial purposes. Up to 40% may be used for ancillary or supporting uses, such as an office that serves the industrial operation. This is the rule commonly called the 60/40 use quantum, and on a multi-user development it applies to each strata-subdivided unit individually — not just to the building as a whole. Every unit at GATE+ Tukang is subject to it, so it is worth understanding before you decide which suite suits your operation. Figures here are as at September 2026.
Industrial land in Singapore is scarce and is zoned specifically to keep production, assembly, warehousing and similar activity viable. Without a quantum control, industrial space would steadily be absorbed by office and showroom uses that can afford higher rents elsewhere. The Urban Redevelopment Authority therefore sets a minimum predominant-use share for Business 1 and Business 2 developments alike.
Two layers apply to a development like this one. At building level, at least 60% of the total industrial gross floor area is for predominant industrial use, and up to 40% covers ancillary uses together with all the common areas outside the units — corridors, staircases, lifts, toilets and M&E spaces. At unit level, because GATE+ is a multi-user development with 265 strata units, each individual unit must separately keep at least 60% of its own floor area in industrial use. Meeting the building-level figure does not exempt a unit from meeting it too.
Predominant use covers the activities the building exists for: manufacturing, processing, assembly, repair, warehousing and storage, product design and development, and industrial training. Certain e-business and core media activities are also treated as industrial and count within the 60%, though data centres require prior planning permission and an assessment with the relevant technical agencies before the premises can be used that way.
Ancillary use is the supporting half of the picture: an office serving the operation, a staff pantry or rest area, a showroom displaying what the business makes. The distinction is function, not furniture. An office that administers the production happening in the same unit is ancillary. An office that is the whole business, with no industrial activity behind it, is not an ancillary use at all — and that is the case the rule exists to prevent.
The practical question is how much usable office you actually need, and whether the unit you are considering can carry it inside 40%. On an entry unit of about 1,615 sq ft, 40% is roughly 646 sq ft of ancillary space — enough for a genuine office, meeting area and pantry supporting a production floor. If your operation needs more administrative space than that, the answer is a larger unit rather than a larger share, or amalgamating units into a bigger floorplate.
Suite format matters here too, because the three types at GATE+ differ in height and access rather than in the use rule. The guide to the Grand, Standard and Pent Suites sets out how they differ, and the full unit mix with sizes is on the GATE+ floor plan page. Units can be combined into larger floorplates subject to the floor plans and the approval of the managing agent and the relevant authorities.
Use quantum is not a formality that is quietly ignored. Breaches attract enforcement action, and changing the intended use of a unit — turning a factory unit predominantly into a showroom, for instance — requires a change-of-use application to the authorities, which is assessed on the merits and may be refused. Any approval can carry further cost consequences.
For a buyer the sensible sequence is simple: confirm the activity you intend to carry on, check it sits within the predominant uses allowed in a B2 zone, then size the unit so the supporting office fits inside 40%. If your intended activity is unusual, uses not specifically listed are evaluated case by case, so confirm it with the authorities rather than assuming. The GATE+ project details page sets out the building specification, and the GATE+ sales team can talk through how a specific operation would sit in a specific unit.
