HDB Renovation: budgeting for built-in carpentry

HDB Renovation budgets get reshaped most by one thing: built-in carpentry. Wardrobes, kitchen cabinets, and the TV console are where a modest quote can balloon or stay sane, depending on the choices you make. Plan the carpentry line early, because it is the single biggest swing factor in your total bill.

What drives the carpentry cost

Carpentry is priced by size, material, and detail. Three things move the number more than anything else:

• Board material: basic laminate over particle board is the value choice; veneer or solid finishes climb fast.
• Volume: full-height wardrobes and floor-to-ceiling cabinets add length you pay for by the foot.
• Internal fittings: soft-close hinges, pull-out trays, and branded runners add up quietly.

A simple laminate wardrobe can be modest, while a fully fitted walk-in with glass panels and lighting sits at the top of the range. The same flat can land at very different totals based on these picks alone.

Carpentry's share of the whole job

In a typical HDB reno, carpentry often takes a large slice of the budget, sometimes more than tiling or painting combined. Based on recent market observations, a 4-room BTO reno typically ranges from S$30k to S$50k, and a good chunk of that is cabinets and wardrobes. For a 5-room BTO that typically ranges from S$40k to S$60k, the bigger floor area means more carpentry to fill.

Resale flats usually need even more, because older ones may have little usable built-in storage to begin with. A resale 4-room reno typically ranges from S$50k to S$80k+, and carpentry is a big reason why.

Kitchen cabinets: the heavy hitter

The kitchen is where carpentry cost concentrates. A standard L-shape or galley run with base and wall cabinets eats more board than most bedrooms combined. To keep it sensible:

1. Fix the layout before quoting, so you are comparing the same cabinet length across firms.




2. Choose a mid-grade laminate that handles heat and steam near the hob.
3. Add soft-close only where you will feel it, like the bin drawer and everyday doors.
4. Skip the fancy internal systems you will not use; a plain shelf often does the job.

A practical, well-built kitchen beats a showroom kitchen you cannot actually cook in.

Wardrobes without the overspend

Bedroom wardrobes are the other big ticket. A few habits keep them within budget:

• Go full-height to the ceiling instead of building a separate loft, you get more storage per dollar.
• Use hinged doors where there is swing space; sliding tracks cost more and need care.
• Keep the internals simple: a mix of hanging and shelves covers most needs.
• Reserve the premium finish for the door face you see, not the carcass hidden inside.

This way the wardrobe looks custom but does not carry a custom price across every panel.

Setting the carpentry line early

The smart move is to give carpentry its own budget line before you collect keys, then design around it. Decide what is must-have, like the kitchen and one bedroom wardrobe, and what is nice-to-have, like a feature console. If the quote comes in high, trim the nice-to-have first, not the build quality.

Built-in carpentry is what makes a flat feel finished, so it deserves real planning, not a last-minute number. Get the material and volume right, and your HDB renovation stays on budget while every room still feels made for you.
