Choosing a detached factory, a semi-D, or a terrace unit is one of the biggest decisions a business makes. The factory type shapes your cost, your power supply, your privacy, your growth — even your resale value.
This guide breaks down the 7 key differences between the three formats. It draws on real Penang market data and years of industrial deals across Batu Kawan, Bukit Minyak, Perai, Juru and Valdor. By the end, you will know exactly which factory type fits your operation.
What Is a Detached Factory?
A detached factory stands alone on its own plot of land, with clear space on all four sides. It shares no walls with neighbouring units. This is the premium format in Malaysian industrial property.
A detached factory usually offers the largest floor plate, the highest power supply capacity, the tallest ceilings, and the widest driveway for trailer access. It also allows for future expansion within the same plot — a major consideration for growing manufacturers.
✅ Best For
MNCs, heavy manufacturing, high-power operations, logistics hubs, and businesses planning future expansion.
⚠️ Trade-Off
Highest price per unit and per square foot. Higher quit rent, assessment fees, and maintenance responsibility.
What Is a Semi-Detached Factory?
A semi-detached factory (semi-D) is built as a pair of units sharing one common wall. Each unit has its own plot, its own driveway, and its own front and rear access. Semi-D units strike a middle ground between the premium detached format and the compact terrace format.
For most SMEs in Penang, a semi-D factory offers the best cost-to-benefit ratio. You get 3 sides of clear space, good power capacity, decent ceiling height, and enough yard for loading — at meaningfully lower cost than a detached factory.
✅ Best For
SMEs, mid-scale manufacturers, MNC supplier companies, and businesses balancing cost with growth room.
⚠️ Trade-Off
One shared wall means slightly less privacy and some noise transfer. Expansion is limited to your own plot.
What Is a Terrace Factory?
A terrace factory sits in a row of connected units, sharing common walls on both sides. Only the front and back are open. This is the most compact and affordable industrial format in Malaysia.
Terrace factories work well for light industrial use, small assembly, packaging, warehousing, and workshop operations. They typically come with lower power supply, shorter ceiling height, and a smaller floor plate — but at prices that make sense for start-ups and lean operations.
✅ Best For
Start-ups, light assembly, packaging, small workshops, warehousing, and cost-sensitive tenants.
⚠️ Trade-Off
Two shared walls limit privacy, power supply, and heavy machinery. No room to expand on the same plot.
Detached Factory vs Semi-D vs Terrace: 7 Key Differences
Here is a side-by-side comparison of the three factory types on the seven factors that matter most to buyers and tenants.
| Factor | Detached | Semi-D | Terrace |
| Shared Walls | None | 1 side | 2 sides |
| Land Area | Largest | Medium | Smallest |
| Typical Power Supply | 400–1,200 AMP | 200–600 AMP | 100–200 AMP |
| Ceiling Height | 25–35 ft | 20–30 ft | 18–24 ft |
| Privacy & Security | Highest | Good | Moderate |
| Expansion Potential | Yes, on-plot | Limited | None |
| Relative Price | Highest | Mid-range | Most affordable |
💡 Rule of thumb: A detached factory costs roughly 40–70% more than a semi-D of the same built-up area. A semi-D typically costs 20–40% more than a terrace unit. Actual pricing varies by park, tenure and specs.
Which Factory Type Should You Choose?
The right factory type depends on four things: your power requirement, your production volume, your growth plan, and your budget. Here is a practical framework based on real Penang deals.
Choose a Detached Factory if…
You run heavy manufacturing, need 400 AMP or more, use overhead cranes, expect frequent trailer traffic, or plan to expand within 3–5 years. A detached factory also makes sense if privacy and brand image matter for MNC clients or audits.
Choose a Semi-D Factory if…
You run mid-scale manufacturing, need 200–600 AMP, want good yard space for loading, and want to keep unit cost reasonable. Semi-D is the most common choice for SMEs and MNC supplier companies in Penang Mainland.
Choose a Terrace Factory if…
You run light assembly, packaging, workshop, or small warehousing operations. Terrace units keep monthly cost low, which suits start-ups and lean operations that don’t need heavy power or tall ceilings.
📌 Pro tip: Match power supply to your machinery load — this is the single most common mistake. Under-powered factories cost tens of thousands to upgrade later. Always confirm the TNB supply capacity on the specific unit before you sign. See the TNB Business portal for supply upgrade guidance.
❓ Frequently Asked Questions
What is the difference between a detached factory and a bungalow factory?
In Malaysian industrial property, “detached factory” and “bungalow factory” describe the same format — a standalone building on its own plot with clear space on all four sides. Some agents use “bungalow” to signal a premium, oversized detached unit.
Is a semi detached factory in Malaysia a good investment?
Semi-D factories offer strong rental yields in Penang Mainland and Kedah, especially near industrial hubs like Batu Kawan and Bukit Minyak. Freehold titles hold value well, and the mid-price bracket attracts a large tenant pool of SMEs and MNC suppliers.
Can I convert a terrace factory into a semi-D or detached?
No. The factory type is fixed by the original land title, plot boundary and building plan. You cannot merge two terrace units to create a semi-D unless the land titles are combined and approved by the local authority — a rare and complex process.
Which factory type has the best resale value?
A detached factory in a mature MNC-anchored zone (like BKIP) usually holds resale value best. Semi-D units are next, with a wide buyer pool. Terrace units resell faster but with lower capital appreciation.
What is the typical rental yield for a factory in Penang?
Penang industrial rental yields typically fall between 4% and 7% per year, depending on zone, factory type and tenure. Semi-D units in growing zones often reach the higher end because the tenant pool is deep.
What is the standard factory tenancy term in Malaysia?
Under Malaysian practice, a standard commercial tenancy runs 2 to 3 years with an option to renew. Terms longer than 3 years are usually registered as a lease at the Land Office. YC Tang can guide you through documentation and stamp duty.
How do I choose between detached, semi-D and terrace?
Start with your power supply need and your growth plan. If you need 400 AMP or more, or plan to double your floor area within 5 years, go detached. If you need 200–600 AMP with good yard, choose semi-D. For light operations under 200 AMP, terrace works well. Call YC Tang at 019-4499725 for a matched shortlist.
