Intro
Many homeowners assume custom carpentry is just about buying a wardrobe. It is not. It is about fit, finish, and who fixes it when the door sags. In Singapore, humidity and tight HDB footprints make this decision harder than it looks. I researched this list because I wanted to know who actually builds the units, not just who signs the contract. The gap between a design studio and a workshop is where most complaints start. This list separates firms that control production from those who outsource it. That distinction matters more than the logo.

| Measurement and templating process | HDB walls are rarely square. | Site measurement after hacking and plastering. |
| Itemised quote with carpentry run rates | Package pricing hides where the money sits. | Each run priced by length or unit. |
| Warranty and defect handling | Doors sag and runners fail in the first year. | A written warranty period and named contact. |
| Experience with your property type | HDB, condo, and landed rules differ. | Recent projects in your property type. |
| After-handover follow-up | Touch-ups decide whether the job feels finished. | A scheduled post-handover visit. |

FAQ
How much does custom carpentry cost in Singapore?
Expect to pay SGD 3,000 to 6,000 for a standard built-in wardrobe in an HDB flat. Kitchen cabinets cost more, often SGD 8,000 to 15,000 for a full setup. Prices vary based on board quality and hardware. A full home renovation including carpentry can range from SGD 30,000 to 80,000. Always ask for an itemised quote to compare costs accurately.
Plywood or particle board for kitchen cabinets in Singapore?
Plywood is generally better for kitchen cabinets in Singapore. It handles humidity and moisture better than particle board. Particle board can swell and warp in high humidity areas. Use plywood for base cabinets and particle board for wall cabinets if budget is tight. Always ask for a written specification of the board grade.
Can I engage a carpentry workshop directly without hiring an interior designer?
Yes, you can engage a carpentry workshop directly. This can save on design fees. However, you will need to provide detailed drawings and measurements. Ensure the workshop has experience with your specific flat type. This approach suits owners who are confident in their design skills.
Do I need an HDB permit to install built-in carpentry?
Yes, you need an HDB permit for built-in carpentry. The permit ensures compliance with safety and structural guidelines. You must apply through an HDB-registered contractor. Unauthorized work can lead to fines and mandatory removal of the units. Always confirm the contractor is registered with HDB.
Is custom carpentry worth it compared with buying ready-made furniture for an HDB flat?
Custom carpentry is worth it if you want a perfect fit and maximise space. Ready-made furniture may leave gaps and waste space. Custom units can be tailored to your exact dimensions and storage needs. The cost is higher, but the longevity and functionality often justify the investment. Consider your budget and long-term plans before deciding.
