Most homeowners begin the renovation process with a broad sense of what they want to spend, but without a clear picture of where that money actually goes. Then the quotes come in and certain line items are unexpectedly large. If you have ever wondered which parts of a renovation cost the most — and why — this guide gives you a straightforward answer.

The Two Biggest Cost Drivers: Concrete Work and Custom Cabinetry

Setting aside design fees, the two renovation categories that consistently account for the largest portion of the budget are concrete and masonry work (structural and wet works) and custom cabinetry (joinery and furniture).

Both have become significantly more expensive in recent years, driven by several converging factors:

Rising labour costs: Skilled workers willing to take on the physical demands of masonry and tiling are in shorter supply. When supply drops, rates go up
Material price increases: Cement, sand, tiles, timber boards, and hardware have all seen notable price increases over the past few years
Skill requirements: A good masonry contractor or cabinet maker is the product of years of accumulated experience. There is no shortcut to producing that expertise

The cost of these two trades reflects not just materials, but the skill and time required to do them properly.

Concrete and Masonry: Why Does Touching a Wall Cost So Much?

Homeowners often underestimate how quickly masonry costs accumulate. “Just knocking down a wall” or “just moving a few tiles” sounds straightforward — until the invoice arrives.

The scope of concrete and wet works is broad: wall demolition and rebuilding, floor tile laying, wall tiling, drainage pipe rerouting, waterproofing layers, and more. Each one of these tasks requires trained labour and takes time. Structural alterations — particularly anything involving load-bearing walls — require professional assessment and careful execution.

The practical reality: even modest demolition and reconstruction work can easily run into five figures (RM). If your budget is limited, think carefully before committing to structural changes:

Is this change genuinely necessary, or is it desirable? Would omitting it significantly reduce your quality of life in the space?
Can an alternative approach — such as custom furniture, a partition screen, or clever storage — achieve a similar spatial effect without breaking through walls?
Have you accounted for the full scope of the change, including all associated trades it triggers?

When budgets are tight, minimise structural works and focus spending on the elements that affect daily living the most.

Custom Cabinetry: Where Does the Cost Come From?

Custom cabinet costs are driven by several distinct factors working together:

Material quality and selection Board materials range widely in quality and price — from chipboard to plywood, from standard melamine paper interior linings to PVC linings, with significant cost differences at each step up. Add the external surface treatment (typically a laminate layer), and hardware components (hinges, drawer slides, handles, pull-out baskets), and the total quickly becomes substantial.

Labour and production time Custom joinery is hand-crafted work. A fully custom cabinet involves measuring, design confirmation, cutting boards to size, hand-applying surface finishes, edge-banding, and finally on-site installation. A quality cabinet can take two to three days to produce in the workshop and another one to two days to install on site. Every hour of skilled labour adds to the cost.

Precision requirements Custom cabinetry must fit the actual dimensions of your space exactly. Every corner, every gap, and every clearance measurement matters. If there is any discrepancy between the design drawings and the site conditions, additional time and material are needed to resolve it — which adds to the final cost.

How to Plan Sensibly: Essential vs Non-Essential

When working with a limited budget, the most important step is distinguishing between what is essential and what is desirable.

Essential items are those that, if omitted, would meaningfully affect your ability to live comfortably in the space:

The kitchen (fundamental to daily cooking and eating)
Plumbing changes (especially if existing pipes are aged or poorly laid out)
Bathrooms (non-negotiable baseline functionality)

Non-essential items improve quality of life but can be deferred:

Feature walls and decorative wall treatments
TV cabinets and display shelving
Large-scale cabinetry expansions beyond basic storage needs
Decorative ceiling works

A practical renovation strategy:

Get the essential items right first — ensure baseline living functions are properly catered for
Defer non-essentials — move in, live in the space for a while, and then decide what you actually need versus what seemed appealing at the planning stage
Do not spend every last dollar on renovation — life continues after the work is done, and having a financial buffer matters

Why Do Renovations So Often Go Over Budget?

Budget overruns in renovation are common, and the causes are usually predictable:

Vague contracts that allow scope creep: Line items not clearly specified in writing allow contractors to charge extras later. Always insist on a fully itemised contract
Mid-project design changes: Every change request after work has begun generates additional material and labour costs. Nail down your design before the first nail goes in
Underestimating the complexity of older properties: Refurbishing an older home typically involves hidden costs — removing old materials, dealing with aged plumbing, and rectifying previous substandard work
Choosing the cheapest contractor and paying twice: Rectification work after a failed renovation almost always costs more than doing it properly the first time

Do What You Can Afford Now. Do the Rest Later.

Renovation is not a once-in-a-lifetime decision that must be perfect on the first attempt. Once you move in, you will quickly learn which aspects of the space genuinely affect your daily comfort and which ones you were excited about during planning but turn out to matter less in practice.

It is entirely legitimate to simplify certain elements now and revisit them in a few years when your budget allows. The goal is not to produce the most impressive renovation possible — the goal is to create a comfortable, functional home within a budget that does not leave you financially stretched afterwards.

Renovation money spent well is money that lets you live well. That is the right measure of success.

Conclusion

Concrete work and custom cabinetry are the two biggest cost categories in most home renovations in Malaysia and Singapore, driven by skilled labour scarcity, rising material costs, and the genuine complexity of doing these things well. When planning your budget, lead with the essential items, keep non-essentials flexible, and resist the pressure to do everything at once.
