If you’ve just gotten the keys to an empty unit, or you’re staring at a terrace house you’ve lived in for ten years and thinking “okay, time for a change” — you’ve probably already started Googling numbers. And you’ve probably noticed the numbers don’t agree with each other. One site says RM80k, another says RM300k, your neighbour’s cousin did hers for “not much lah” and won’t say more.
Here’s the honest answer: there isn’t one number, because your renovation isn’t the same as anyone else’s. What actually matters is understanding why costs move the way they do — how much hacking is involved, how many rooms you’re touching, whether your wiring is from 1995 or last year, and how particular you are about the finishes. Once you get a handle on that, you can plan a budget that actually makes sense for your home, instead of anchoring on a number you saw online that has nothing to do with your unit.
This is especially true if you’re drawn to the clean, calming look of Japanese interior design in Malaysia — that kind of finish rewards good planning and punishes rushed decisions. So let’s talk through what actually moves the needle on cost, whether you’re in a condo in Mont Kiara or a double-storey terrace in Bukit Jalil.
1. Condos: It’s Not Really About Size, It’s About Scope
Renovating a condo comes with its own headaches that have nothing to do with money — service lift bookings, JMB rules about working hours, lift protection deposits, the works. But cost-wise, what really matters is how much you’re changing, not how big your unit is.
Think of it more like three rough levels of “how much are we touching”:
- A light refresh — new paint, better lighting, a few built-ins here and there. Minimal disruption, quick to finish, barely any structural work involved.
- A proper overhaul — ripping out the developer-grade tiles, opening up the layout, custom carpentry in most rooms. This is what most people picture when they say “renovation.”
- A fully bespoke job — imported materials, smart home wiring, furniture built specifically for your space. This is a different conversation altogether, and it should be treated as one.
What pushes you from one level to the next isn’t the size of your unit — it’s how much hacking and rewiring is involved, how many rooms get touched, and how custom you want the carpentry to be. A small unit with a full gut job can easily cost more than a bigger one that needs a cosmetic update.
2. Own a Landed House? The Maths Works Differently
Landed houses play by different rules. You’ve got an outside to deal with too — the roof, the car porch, the autogate, maybe an extension you’ve been dreaming about for years. All of that eats into the budget before you’ve even walked through the front door.
A helpful way to think about it is by roughly how your Ringgit tends to get split, rather than a fixed price:
| Where the money tends to go | Rough share of the budget |
| Structure & exterior (roof, extension, autogate) | 25–35% |
| Carpentry & built-ins | 25-30% |
| Kitchen & wet areas | 15–20% |
| Electrical, plumbing, aircon | 15-20% |
| Flooring, paint, fittings | 10–15% |
| Buffer for the unexpected | 5–10% |
Your own split will look different depending on what you’re actually doing. Adding an attic or pushing the kitchen back? Structural work eats a bigger chunk. Just refreshing the interior without touching the shell? More of your budget goes into carpentry and finishes instead. There’s no “correct” split — just what makes sense for your project.
3. Why the Kitchen Always Eats the Biggest Chunk of the Budget
Ask anyone who’s renovated before — the kitchen is where the money goes. It’s not really the size of the room that does it; it’s how many different trades and materials have to come together in one space. Plumbing, electrical, carpentry, stone work, appliances — all in one relatively small footprint.
- Cabinetry: Cabinet costs depend on more than just the cabinet finish. Material selection, internal carcass construction, hardware brands (such as Blum or Hettich), storage accessories, and the level of customisation all play a part. Rather than comparing prices by linear foot alone, it’s more important to choose materials that suit your lifestyle, durability expectations and budget.
- Countertops: Quartz and sintered stone are both popular choices for modern kitchens. Quartz offers excellent value and a wide range of colours, while sintered stone provides superior heat and scratch resistance. The right choice depends on how you use your kitchen and the overall design concept, rather than simply choosing the latest trend.
- Built-in Appliances: Appliance costs vary significantly depending on the brands and features you choose. Instead of deciding based on price alone, consider how you cook, your available space, and whether built-in appliances will improve the functionality of your kitchen in the long run.
More homeowners these days are asking for a wet-and-dry kitchen split, and quite a few are specifically looking for a Japanese contractor in Malaysia who can pull off that “Japandi” look — warm wood tones next to clean, minimal cabinetry.
A few things that genuinely move your kitchen budget up or down. Laminates cost more than basic melamine, but they hold up a lot better against Malaysia’s humidity — worth it long-term, even if it stings upfront.
- Your countertop choice. Sintered stone has become the go-to over quartz lately because it handles heat better, but price still swings a lot depending on slab size and how the edges are finished.
- How many appliances are you building in? An oven, hood, hob, and fridge can be sourced at very different price points — the layout and ventilation planning matter just as much as which brand you pick.
- How complicated your layout is. An island or a full wet-dry split means more plumbing and wiring runs, which usually affects your labour cost more than your material cost.
Instead of trying to work backwards from a per-foot rate, it’s more useful to just be honest with yourself first — is durability your priority, or the look, or fitting more into the same space? Once you know that, the actual costing becomes a much easier conversation with your designer.
4. The Stuff People Call “Hidden Costs” (It’s Usually Just Poor Planning)
You’ve probably heard renovation horror stories about “hidden costs” that blindside people halfway through. Honestly, most of these aren’t hidden at all — they’re just things nobody bothered to check for before the quote was written.
- Old wiring. A lot of older units and houses need partial or full rewiring. A proper site visit before work starts will tell you this immediately — it shouldn’t be something your contractor discovers with the walls already open.
- Waterproofing. Bathrooms and wet areas need a proper membrane done right the first time. It’s not glamorous, and it’s tempting to skip, but redoing a leak later always costs more — in money, time, and patience — than doing it properly from the start.
- Permits. DBKL, MBPJ, or JMB approvals for anything structural are known requirements. A contractor who’s done this before will already have these built into your timeline, not springing them on you in month three. Cost between RM5,000 to RM15,000.
Honestly, the difference between a renovation that goes smoothly and one that turns into a saga isn’t usually the size of the budget. It’s whether someone actually walked the site, asked the right questions, and priced these things in from day one.
5. Two Homeowners, Two Very Different Approaches
It helps to see how this plays out in real life, so here are two recent projects — not to compare price tags, but to show how different priorities lead to different decisions.
The Subang Jaya condo. A roughly 1,100 sq. ft. unit, going for a modern Japanese minimalist look. The owners cared most about custom carpentry — wardrobes, a proper TV console — and a kitchen that actually worked for how they cooked. So that’s where most of the budget went. They deliberately kept hacking to specific spots instead of gutting the whole unit, which kept both the cost and the timeline in check.
The Shah Alam terrace. A 22′ x 75′ double-storey house going for a contemporary industrial feel. Here, the big-ticket item was a rear extension for more living space, plus a full retile and a roof replacement. Because the extension and roof affect literally everything else in the house, that work got sequenced first — carpentry and finishes were only finalised once the structural side was locked down.
Neither family had an unlimited budget. What they had in common was clarity — they knew what mattered most to them, and they let that drive the sequence of decisions instead of trying to do everything at once.
6. Be Careful Chasing the Cheapest Quote
It’s tempting to just go with whoever quotes the lowest number. But if one quote is way below everyone else’s, ask yourself why. Materials haven’t gotten cheaper — if anything, prices have stayed pretty volatile. So a much lower quote usually means something’s being cut somewhere: thinner piping, a skipped waterproofing layer, or electrical work that’s under-specced and will need fixing down the road anyway.
When you’re working with someone who genuinely understands Japanese interior design in Malaysia, you’re not just paying for how it looks. You’re paying for how carefully it’s built — the kind of attention to detail that means you’re not redoing work two years later.
7. What We Do Differently at GGE Design Studio
We don’t try to win jobs by being the cheapest quote in the room. What we bring instead is a Japanese-style approach to actually managing the project, start to finish:
- We show you the numbers upfront. A clear scope and transparent cost breakdown help homeowners understand where their budget is being invested and reduce unexpected variation orders later.
- We give you a timeline you can actually trust. Not an optimistic guess, but a realistic schedule with clear checkpoints along the way, so you always know where things stand.
- We don’t let changes sneak into your bill. If something changes mid-project, it gets written down, costed, and approved by you before we touch it — so your final invoice never has surprises hiding in it.
- We check the work as we go, not just at the end. Regular site inspections mean we catch problems while they’re still small and cheap to fix, instead of at the final walkthrough when it’s too late.
Basically, we’d rather your renovation feel like a well-run project than a leap of faith.
8. Questions Homeowners Actually Ask Us
How long will this take?
A condo usually takes about 2 to 4 months. A landed house with an extension is more like 6 to 10 months. Any contractor worth their salt will also build in some buffer time for the hacking stage — that’s normal, not a warning sign.
Should I just buy furniture, or go custom?
Loose furniture is cheaper to start with, but built-ins make much better use of space, especially in a condo where every square foot counts. A lot of homeowners land somewhere in between — custom kitchen and wardrobes, then nice loose pieces for the living room.
Do I need an interior designer, or can I just hire a contractor directly?
If you’re going for something with a real aesthetic thread running through it — like a Japanese-style home — an ID earns their keep by keeping everything cohesive. If you just need one thing done, like new flooring, a direct contractor is fine, though you’ll be the one keeping an eye on the project.
What’s the smartest way to save money without the place looking cheap?
Keep what’s still good. If your existing tiles or flooring are in decent shape, laying SPC or vinyl over them saves you the cost of hacking and disposal, and it can still look completely fresh.
How do people end up blowing their budget?
Almost always the same way — not being clear on priorities from the start, and letting small changes get added verbally along the way without anyone writing down what they cost. Fix those two things, and you’re most of the way there.
A Few Practical Tips Before You Start
- Figure out your must-haves first. Kitchen? Storage? Layout? Whatever matters most to you should get first pick of the budget.
- Insist on a proper site visit before you get a quote. This is how electrical, plumbing, and structural issues get caught early instead of mid-project.
- Leave some room — 5 to 10% — for the unexpected. Not because something will definitely go wrong, but because it takes the pressure off if plans shift.
- Ask for your quote broken down by category, not just one total. It’s much easier to see where you have room to move.
- Do the structural stuff first, cosmetic stuff after. Extensions, rewiring, waterproofing — get these locked in before you start picking paint colours.
- Work with people who put changes in writing. A quick “sure, we can throw that in” over WhatsApp is exactly how budgets quietly creep up. Get it documented.
The Bottom Line
Renovating your home doesn’t have to feel like you’re guessing your way through it, hoping the bill doesn’t blow up halfway. Once you understand what actually drives the cost — scope, sequencing, material choices — the whole process gets a lot less stressful, and you stop chasing benchmark numbers that were never really about your home in the first place.
At the end of the day, this is your space, and it should feel like it was built with you in mind — whether that’s a calm, Japanese-inspired feel or something completely different. At GGEのデザインスタジオ, we care as much about how the project runs as we do about how it turns out — clear numbers, realistic timelines, and no nasty surprises along the way.
If you’d rather plan this properly than guess your way through it, we’re happy to sit down, walk through your space, and give you a consultation and planning session.
